- Abstract
GLO:OL3/07nov22:ange202213688-fig-0002.jpg PHOTO (COLOR): 2 The electrochemical behaviors of Gr electrodes under different formation temperatures. a) The voltage evolution profiles of Li||Gr half cells under different working temperatures to indicate the capacities and initial coulombic efficiencies. b) Schematic diagram of Gr||Gr cell and its equivalent circuit used for the impedance analysis, with the only impedance of Li+ migrating through SEI (Rt). The TEM images of Gr electrode with SEI thickness under formation temperature of a)+40 °C, b)+25 °C and c) -20 °C, respectively. d-f) The fitted XPS analysis (C1s, F1s, O1s spectra) of Gr electrodes under different formation temperatures. gl The impedance evolution profiles of Gr||Gr cells (with different SEI formation temperatures) under test temperature of c)+40 °C, d)+25 °C and e) -20 °C, respectively. f) The corresponding fitted Rt values under different test temperatures. gl GLO:OL3/07nov22:ange202213688-fig-0003.jpg PHOTO (COLOR): 3 The SEI film analysis of Gr electrodes under different formation temperatures.
