Lithium battery materials, currently in use, fall short in terms of safety and performance holding back the next generation of high-performance batteries. In particular, the development of the electrolyte poses a key challenge for higher power batteries suitable for energy storage and vehicle applications. Researchers in Australia have synthesized safe fluoroborate salts with battery grade purity by recrystallisation process. When put in a lithium battery with lithium manganese oxide cathodes, the cell cycled for more than 1000 cycles, even after atmospheric exposure. The salt was found to be very stable on aluminum current collectors at higher voltages, as required for next generation batteries. According to the researchers their future effort is to turn the new anions into thermally stable, non-flammable liquid salts, making them beneficial for batteries operating at high temperatures…read more.
