Energy Storage, Electrolyte Additives, Rechargeable Batteries, Lithium Ion Batteries (LIBs) and Lithium Metal Batteries (LMBs), Sodium Ion Batteries (SIBs), and Potassium Ion Batteries (KIBs).
Inventors have developed a library of safe redox shuttle additives based on cyclopropenium salts of trisaminocyclopropenium perchlorate (TAC) and its derivatives for overcharge protection in rechargeable batteries including LIBs, alkaline, LMBs, SIBs and KIBs. Studies have shown that during the overcharging process, the redox-active TAC can repeatedly shuttle between two electrodes, maintaining the cell voltage within a safe value. Furthermore, a distinctive electrochromic behavior of TAC electrolyte can provide the device an overcharge alarm to further enhance the safety level.
