Electrolyte design for ultra-stable, low-temperature lithium-ion batteries

Ester-based electrolytes significantly broaden the operating range of lithium-ion batteries (LIBs) at low temperatures. However, the gas formation in low-temperature ester electrolytes limits the lifespan of batteries. Recently in Matter, Zhang and coworkers reported a high-concentration electrolyte (HCE) design that inhibits gas generation and achieves an ultra-long lifespan of LiNi0.8Co0.1Mn0.1O2|| graphite pouch cells at low temperatures.
