High-voltage LiNi0.4Co0.4Mn0.2O2/graphite pouch battery cycled at 4.5 V with a LiDFP-based electrolyte

Increasing the charging cutoff voltage is an effective method for improving the energy density of lithium-ion batteries. However, the conventional carbonate-based electrolyte with LiPF 6 is unstable when the end-of-charge voltage up to 4.5 V (vs. Li/Li + ), resulting in poor cycling stability of LIB...
