Insight into structural degradation of NCMs under extreme fast charging process

A multi-functional electrolyte additive for fast-charging and flame-retardant lithium-ion batteries

“…For example, graphite anodes have shown higher capacities and improved cycling stability in HCEs and LHCEs at high rates, attributed to reduced desolvation energies and accelerated Li + kinetics facilitated by anion-derived SEIs. 28–31 However, conventional HCEs and LHCEs remain flammable. Recently, Zou et al developed an all-fluorinated, flame-retardant electrolyte, composed of LiPF 6 in mixed solvents of methyldifluoroacetate (MDFA), ethoxy(pentafluoro)cyclotriphosphazene (PFPN), 32 and fluoroethylene carbonate (FEC) for LIBs.…”
