Electrochemical Analysis of the Hard Carbon/Electrolyte Interface in Lithium-Ion Batteries at Low Temperature: Fluoroethylene Carbonate as an Electrolyte Additive.
The propylene carbonate (PC)-based electrolyte system is characterized by a wide liquid range and favorable Li+ migration kinetics, which endows it with excellent low-temperature applicability when paired with hard carbon (HC) anodes in lithium-ion batteries (LIBs). However, the PC-induced SEI structure is loose, which...
