The advent of miniaturized electronics and wearable technology has precipitated an urgent need for flexible, lightweight power sources compatible with dynamic, irregular surfaces. Existing batteries, predominantly lithium-ion or alkaline chemistries, often suffer from inherent rigidity and bulky form factors that impede seamless integration into next-generation devices. Moreover, their reliance on hazardous chemicals raises environmental and health concerns, exacerbated by the potential for leakage. While energy harvesters provide an alternative by generating power from ambient conditions, their output is frequently insufficient or inconsistent for sustained device operation. The MAB’s design champions a paradigm shift by amalgamating the convenience of an energy harvester with the reliability and capacity associated with traditional batteries.

At the core of this moisture-activated battery lies a novel composite structure featuring a magnesium anode paired with a silver/silver chloride cathode, separated by a cellulose membrane embedded with lithium chloride salts. This unique separator functions not merely as a physical barrier but as an active medium for electrolyte formation. It absorbs moisture from the surrounding environment, dissolving the lithium chloride salt to produce a saltwater electrolyte essential for ionic conduction within the battery. This approach eradicates the need for pre-impregnated or volatile electrolytes, substantially enhancing safety and extending shelf life by maintaining the battery in an inert state until activated by atmospheric humidity.

A remarkable aspect of the MAB’s architecture is its bioinspired stratagem modeled after pangolin skin. This natural design motif, comprising densely overlapping scales, confers exceptional mechanical resilience and adaptability. While conventional stretchable batteries utilize serpentine interconnectors to maintain electrical continuity under strain, they are often susceptible to energy density reduction due to gaps formed during deformation. The pangolin-inspired layering enables the MAB to maintain minimal gaps, redistributing mechanical stresses evenly across the battery surface. This ensures sustained electrochemical performance under diverse mechanical deformations, including stretching, bending, and twisting, without sacrificing energy storage capacity.

The mechanics underlying this stretchability were elucidated through sophisticated computer simulations conducted in tandem with empirical assessments. Rice University’s mechanical engineering team demonstrated that the integrated design could withstand significant mechanical deformation while preserving charge transfer pathways and internal resistance characteristics. The synergy of materials science and biomechanics is clearly evident in the MAB’s stable electrochemical output, with an open-circuit voltage around 1.6 volts and a specific capacity approximating 52 milliampere-hours per gram. The specific energy density reaches a noteworthy 81 milliwatt-hours per gram, competitive with many commercial batteries, thus affirming the device’s viability for practical applications.

One compelling demonstration of the battery’s capabilities involved powering a wireless Bluetooth-enabled pulse oximeter continuously for approximately 30 hours. This performance aligns closely with that of conventional rigid batteries but with the added advantages of reduced weight, flexibility, and non-toxicity. Beyond wearables, the MAB’s design opens avenues for embedding safe, conformal power sources in robotics, environmental sensing devices, and distributed surveillance systems. The biocompatible and biodegradable nature of the constituents significantly mitigates ecological impact, addressing growing concerns about electronic waste proliferation.

Of particular interest is the integration of an innovative “kill switch,” leveraging the core moisture harvesting principle to enhance security and tamper resistance in sensitive monitoring applications. This feature involves a dry mixture of aluminum and iodine powder housed within an isolated compartment enveloped by a moisture-absorbing cellulose membrane. Upon mechanical pressure—such as an attempt to remove or disable the device—the mixture interacts violently with the harvested moisture, triggering a rapid exothermic reaction that incinerates the device. This self-destructive mechanism not only protects valuable and sensitive data but also prevents unauthorized reuse, representing a significant advancement in device security, particularly for covert surveillance missions.

Empirical tests of the kill switch embedded within a MAB-powered wireless gas sensor demonstrated total device obliteration within three minutes of activation. This rapid response underscores the system’s efficacy in safeguarding against tampering and adds a layer of fail-safe protection previously unattainable in miniature power systems. The innovation embodies a functional integration of energy harvesting, power storage, and security features within a single compact architecture, indicative of future trends in smart device design where multifunctionality is paramount.

The MAB’s development is a testament to the interdisciplinary collaboration between materials scientists, electrical engineers, and mechanical engineers. The project is backed by the Advanced Self-Powered Systems of Integrated Sensors and Technologies (ASSIST) Center at NC State, with strategic funding to bridge industrial innovation and academic research. Graduate and postdoctoral researchers played vital roles in advancing the technology from conceptual frameworks to demonstrable prototypes, underscoring the team’s commitment to transitioning laboratory breakthroughs into real-world deployments.

Looking ahead, this moisture-activated battery paradigm has the potential to redefine energy solutions for the exploding IoT ecosystem. Its convergence of sustainability, safety, mechanical flexibility, and energy density positions it uniquely to tackle challenges posed by wearable health monitors, environmental sensors, and smart infrastructure. With further refinement, scalability, and integration, MAB technology could soon supplant toxic, rigid batteries, heralding an era where ubiquitous electronics operate safely, efficiently, and harmoniously with natural environments.

The publication of these findings in the prestigious journal Science Advances marks a significant milestone that invites further exploration and adoption within the scientific and industrial communities. By demonstrating that a battery can be activated purely by environmental moisture and engineered for stretchability without compromising capacity, the research opens new horizons in battery chemistry and device engineering. As IoT devices proliferate, the demand for such novel power sources that merge eco-friendliness with advanced functionality will be more critical than ever, making this development both timely and transformative.

In conclusion, the moisture-activated battery represents a groundbreaking advancement in energy storage technology, unlocking promising avenues for the future of wearable electronics and IoT devices. Its safe, flexible, and environmentally benign profile coupled with an innovative security mechanism reflects a holistic approach to power solution design, reflecting the growing complexity and sophistication of modern electronic ecosystems.

Lithium-ion batteries have undeniably transformed the energy storage landscape. Their lightweight nature, high energy density, and reusability make them ideal candidates for a variety of applications ranging from consumer electronics to electric vehicles. However, the performance of these batteries is inherently tied to the materials used in their electrodes. Traditional graphite anodes, while reliable, struggle to meet the ever-increasing demands for higher capacities and faster charging times. This has prompted researchers to explore alternative materials that can offer superior electrochemical properties.

In this study, the focus was directed toward the development of MoS₂/NC composites that not only exhibit enhanced electronic conductivity but also boast high surface area and structural stability. Molybdenum disulfide has emerged as an attractive anode material due to its layered structure, which facilitates the intercalation of lithium ions. The integration of nitrogen-doped carbon contributes to improved electrical conductivity, which is crucial for battery performance, particularly during rapid charge and discharge cycles.

The synthesis of the MoS₂/NC composite was carefully designed to maximize the interaction between the two materials. The researchers employed a hydrothermal method, followed by calcination, to achieve a well-dispersed mixture that preserves the distinct advantages of both components. During the hydrothermal synthesis, the precursors reacted under controlled temperature and pressure, leading to the formation of MoS₂ nanostructures embedded within a nitrogen-doped carbon matrix. This innovative approach not only enhances the composite’s electrochemical properties but also maintains its structural integrity over numerous charge cycles.

Lithium-ion batteries, the cornerstone of modern portable electronics and electric vehicles, have traditionally grappled with critical challenges: flammability risks from organic solvents, energy-intensive production processes, and complicated recycling protocols. Currently, the reliance on volatile organic electrolytes demands strict, resource-heavy manufacturing environments such as dry rooms and glove boxes, inflating production costs and environmental footprints. Furthermore, the complex binders and electrolyte formulations used complicate recycling, often rendering valuable materials unrecoverable. The 3D-SLISE system directly addresses these pain points by presenting a safer, greener alternative without sacrificing performance.

The core of this innovation is a borate-water electrolyte created from amorphous lithium tetraborate combined with a lithium salt, carboxymethyl cellulose, and water. This concoction forms a unique slime-like quasi-solid interface, establishing a three-dimensional ion conduction network that facilitates multidirectional lithium ion mobility. Unlike traditional liquid or solid electrolytes that conduct ions in limited pathways, 3D-SLISE’s isotropic conduction enhances ionic conductivity, reaching values of approximately 2.5 milli-siemens per centimeter. Such conduction efficiency rivals advanced aqueous electrolyte systems while operating effortlessly at ambient temperature, thanks to its low activation energy of 0.25 electron volts.

Fabrication processes further emphasize the sustainability of this system. The slurries constituting 3D-SLISE are naturally dried at room temperature, a stark contrast to the high-temperature or low-humidity conditions demanded by conventional batteries. This ambient fabrication eliminates the need for energy-expensive infrastructures, enabling battery assembly in standard air conditions. Two distinct slurry types are employed: Type E, which integrates with key lithium-based active materials—including lithium cobalt(III) oxide as the cathode and lithium titanate as the anode—to form electrodes, and Type S, which composes the quasi-solid electrolyte layer. The seamless assembly under benign conditions heralds large-scale manufacturability without compromising material integrity.

Performance metrics of batteries utilizing 3D-SLISE are nothing short of remarkable. The assembled cells deliver a stable voltage of 2.35 volts at a 1C rate and consistently sustain over 400 charge-discharge cycles at 3C rates under room temperature, translating to rapid charge and discharge times—around 20 minutes per full cycle. These capabilities indicate that despite being quasi-solid and water-based, the electrolyte competes effectively with, and in some respects outperforms, traditional lithium-ion systems dependent on hazardous organic components. Such battery endurance alongside quick cycling makes 3D-SLISE an optimally practical solution for diverse applications spanning from consumer electronics to grid-scale energy storage.

Beyond performance, the recycling advantages are transformative. Common binders used in lithium-ion batteries, such as polyvinylidene difluoride (PVDF), are challenging to break down, often necessitating harsh chemical treatments. However, 3D-SLISE’s composition excludes these binders and relies solely on water-dispersible components. Used batteries can be dismantled simply by immersing electrodes in water, allowing the active materials—including cobalt, a rare and valuable element—to be directly reclaimed. This straightforward recycling process promises to substantially reduce environmental impact and resource depletion, key attributes aligned with circular economy principles.

The potential environmental benefits extend into the manufacturing chain as well. By circumventing the need for flammable organic solvents, 3D-SLISE considerably reduces fire hazards—a persistent safety concern in lithium-ion battery production and operation. The elimination of dry rooms and glove boxes, which consume significant energy and impose complex operational standards, further reduces the carbon footprint and costs associated with battery fabrication. Collectively, these characteristics place 3D-SLISE as a game-changing technology that aligns industrial scalability with environmental stewardship.

Technically, the incorporation of amorphous lithium tetraborate serves dual functions: it provides a stable structural framework for ion transport and enhances electrochemical stability of the cell. Lithium bis(fluorosulfonyl)imide (LiFSI) salt ensures efficient lithium ion availability, while carboxymethyl cellulose contributes to the desired viscoelastic properties of the quasi-solid matrix. The resulting slime-like interface bridges the gap between solid and liquid electrolyte behaviors, harnessing advantages of both to maximize ionic mobility without compromising safety or manufacturability.

The Institute of Science Tokyo’s commitment to zero-carbon energy technology illustrates the strategic focus underpinning this breakthrough. Spearheaded by Specially Appointed Professor Yosuke Shiratori and Associate Professor Shintaro Yasui, this research is expected to accelerate the transition toward sustainable energy storage by providing practical, scalable technological solutions. Their findings, detailed in the July 2025 issue of Advanced Materials, underscore an interdisciplinary approach, blending materials science, electrochemistry, and environmental engineering.

Looking forward, the adaptability of 3D-SLISE could empower a wide range of battery-dependent technologies. Portable electronics stand to benefit from safer, more durable power sources, while stationary energy storage could leverage the quick charge rates and long cycle life to enhance grid stability and integrate renewable resources more effectively. Furthermore, the ability to avoid toxic solvents and streamline recycling could transform regulatory landscapes, promoting safer consumer products and industry practices globally.

In summary, 3D-SLISE embodies a multifaceted leap forward in lithium-ion battery science. By integrating inherently safe, water-based materials into a quasi-solid matrix capable of high ionic conductivity and manufacturable under ambient conditions, the Institute of Science Tokyo researchers have charted a promising course toward truly sustainable, high-performance batteries. Their discovery not only addresses the immediate challenges of battery safety and environmental impact but also paves the way for a circular battery economy where materials are continuously recovered and reused, reducing waste and dependence on scarce resources.

Traditionally, EMC is produced through the transesterification of two key precursors: dimethyl carbonate (DMC) and diethyl carbonate (DEC). This reaction, however, is fraught with difficulties arising from the nature of the catalysts used. Strong acid catalysts, while effective in promoting the reaction, inadvertently accelerate the hydrolysis of DMC, decomposing it into undesirable byproducts such as methanol and carbon dioxide. On the other hand, alkaline catalysts, typically sodium alkoxides, suffer from poor solubility in the predominantly non-polar reaction medium, resulting in low catalytic efficiency and diminished conversion rates. These drawbacks have collectively limited the development of economically viable, environmentally friendly EMC production at industrial scales.

In a groundbreaking advancement, a collaborative research team hailing from Qingyuan Innovation Laboratory, East China Engineering Science and Technology Co. Ltd., and Fuzhou University has unveiled a novel catalyst system that adeptly addresses these entrenched challenges. Central to their innovation is [DBU⁺][IM⁻]@UiO-66, an acid-base bifunctional catalyst that integrates the complementary catalytic properties within a single, structurally robust material. This synergy not only enhances reaction efficiency but also mitigates side reactions that have traditionally hampered product yield and purity.

UiO-66, a zirconium-based metal-organic framework (MOF), forms the catalyst’s backbone. Renowned for its exceptional porosity, high surface area, and remarkable chemical stability, UiO-66 serves as an ideal scaffold for hosting catalytic active sites. Notably, deliberate defect engineering within UiO-66 introduces acidic sites by creating coordinatively unsaturated zirconium centers. These acidic moieties are pivotal in activating the carbonyl functional groups of DMC and DEC, thereby facilitating substrate adsorption and initial reaction steps.

Complementing these acidic sites, the team immobilized an ionic liquid, [DBU⁺][IM⁻], within the porous architecture of UiO-66. The ionic liquid contributes potent basic active sites, primarily due to the strong nucleophilicity of the 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) cation paired with the imidazolide anion. This duality of acid and base functions operating in close proximity within the same catalyst enhances the formation of reactive intermediates crucial for efficient transesterification. Altogether, the catalyst promotes a concerted mechanistic pathway, accelerating EMC production while suppressing unwanted side processes.

Laboratory evaluations underscore the efficacy of this approach. Under optimized conditions—specifically, a reaction temperature of 100°C maintained over five hours and a catalyst loading of 8 weight percent relative to DMC—the catalyst achieved an impressive EMC yield of 62% coupled with an almost unparalleled selectivity of 99.5%. This near-quantitative selectivity translates to minimal generation of byproducts, an outcome highly desirable for industrial sustainability and downstream processing.

Beyond catalytic performance, stability and reusability are regarded as essential parameters for commercial feasibility. The [DBU⁺][IM⁻]@UiO-66 catalyst demonstrated commendable resilience over repeated reaction cycles. Even after six successive uses, catalytic activity diminished only marginally, with conversion efficiencies tapering minimally from 62% to 58.9%. This sustained performance is attributed to the intrinsic durability of the UiO-66 framework, which effectively preserves the immobilized ionic liquid components, preventing leaching and structural degradation.

The synergy observed in the acid-base catalysis embodied by [DBU⁺][IM⁻]@UiO-66 represents a strategic departure from conventional single-site catalysts. By orchestrating cooperative interactions between acidic and basic sites within a spatially confined environment, the research offers a paradigm shift in the microscopic understanding and macroscopic control of organic transesterification reactions. This advancement not only has direct implications for battery-grade EMC synthesis but also paves the way for designing multifaceted catalysts tailored for precision chemical manufacturing.

Zhaoyang Qi, a corresponding author of the study, emphasized the significance of this breakthrough: “Our catalyst transcends the conventional compromise typically encountered in EMC synthesis. The integration of acid and base active sites within a singular, reusable architecture eliminates undesirable side reactions, elevates efficiency, and crucially aligns with scalable industrial protocols.” Such statements highlight the broader impact beyond pure chemistry, touching on economic and environmental imperatives that surround the transition toward cleaner energy vectors.

Aligned with global trends aimed at decarbonization and energy storage enhancement, this catalytic innovation arrives at a crucial juncture. The ability to reliably produce high-quality EMC not only facilitates higher-performing lithium-ion batteries but also strengthens supply chains critical for electric vehicles and renewable energy grid integration. Moreover, the use of MOF-based catalysts functionalized with ionic liquids exemplifies the versatile, cutting-edge materials science approaches necessary to meet these demands.

This research is distinguished not just by its experimental results but by the strategic design philosophy that underpins it. The meticulous engineering of defect sites in UiO-66 to create acidic centers, combined with the precise immobilization of ionic liquids to furnish base sites, illustrates a sophisticated level of materials tailoring—a trend increasingly defining modern catalysis. Future avenues may explore expanding such bifunctional catalysts toward other industrially relevant reactions, underscoring the broader applicability of these findings.

Given the exceptional catalytic performance and stability, prospects for industrial adoption appear promising. Nonetheless, further scale-up studies, process integration evaluations, and economic assessments remain essential to transition from laboratory proof-of-concept to commercial reality. These steps are anticipated to be facilitated by the catalyst’s compatibility with existing reactor configurations and the use of benign reaction conditions that minimize energy consumption and waste.

This work ultimately symbolizes a milestone in green chemical engineering, where molecular-level insights and materials innovation converge to solve pressing industrial challenges. The dual-site catalytic approach not only elevates the synthesis of a key battery electrolyte component but also exemplifies the direction of future research focused on sustainable, energy-efficient chemical production.
