a Rate Performance of Li|PVM-GPE | NCM811 cell. b Cycling performance of Li | |NCM811 cells with PVM-GPE and PDE electrolytes at 3 C. The cutoff voltage is 4.3 V. c Cycling performance of 4.3 V Li|PVM-GPE | NCM811 cells at 0.5 C using positive electrode with high mass loadings. d Cycling performance of 4.5 V Li|PVM-GPE | NCM811 cells at 0.5 C. e Cycling performance of 4.3 V Li|PVM-GPE | NCM90 cells at 0.5 C. f Cycling performance of the Li|PVM-GPE | NCM811 pouch battery at 0.2 C. g Charge-discharge profiles of Li|PVM-GPE | NCM811 pouch cells at different cycles. h Cycling performance of the Li|PVM-GPE | NCM811 1 Ah pouch battery. (Unless specifically noted otherwise, the areal loading of the battery positive electrode is approximately 3 mg cm−2, 1 C = 188 mA g−1(NCM811), 1 C = 200 mA g−1(NCM90)).
