A smart safe rechargeable zinc ion battery based on sol-gel transition electrolytes

(Science China Press) Thermal runaway has been a long-standing issue impeding the development of high-energy-density batteries. Recently, a research team led by Prof. Chunyi Zhi from City University of Hong Kong has successfully synthesized a temperature-sensitive sol-gel transition electrolyte and incorporated it into a rechargeable Zn/α-MnO2 battery system. The battery operation would be inhibited at high temperature due to gelation of the sol-gel electrolyte and then restore working condition after cooling down, exhibiting a temperature-dependent dynamic electrochemical performance.
