Abstract

En 中文

• The dipole-dipole interaction between DFEA and PC promotes the rapid interfacial Li+ desolvation. • The enhanced anchoring effect between DFEA and PC inhibits the side reactions at the graphite interface. • The optimized electrolyte enables the 4.2 Ah LCO/Gr pouch cells to operate at a wide temperature range of −80 to 60 °C.
