Abstract:

In today's world, where resources are scarce and energy demand is escalating, aqueous zinc-ion batteries (AZIBs) have emerged as a prominent large-scale energy storage technology. They offer advantages such as high safety, low cost, substantial capacity, and rapid charging and discharging capabilities. As the applications for energy storage become more diverse, AZIBs are being explored for use in various extreme environments. However, the free water molecules in the battery can also cause many adverse reactions, resulting in decreased capacity and shortened life. At low temperature, the freezing of solvent water leads to the decrease of ionic conductivity of AZIBs. At high temperature, the rapid evaporation of solvent water will produce bubbles and gas expansion, and the electrode will also be corroded and dissolved. To address these challenges, this review summarizes the latest research progress of aqueous zinc ion batteries at wide temperature range, focusing on the mechanisms of high-concentration electrolytes, gel electrolytes, electrolyte additives, and eutectic electrolytes to lower the freezing point of the electrolyte and to improve the electrochemical performance at low temperatures. Furthermore, the outlook for further improvement of aqueous zinc-ion batteries for a wide range of temperature performances and industrial applications are also proposed.
