Higher Vinylene Carbonate Levels Extend LFP/Graphite Battery Life at 70°C

A new study in the Journal of The Electrochemical Society shows that increasing vinylene carbonate concentrations in LFP/graphite pouch cells significantly improves high-temperature cycling by reducing iron dissolution and suppressing electrolyte degradation, while LiFSI-based cells require LiPF6 to mitigate gas production.
