Fig. 6: Electrochemical performance of 510.3 Wh kg−1 Li metal pouch cell with ultra-high positive electrode ratio.

a Mass distribution of all cell components in the pouch cell. b Detail parameters of the Li metal pouch cell. c Cycling performance of the Li metal pouch cell at 0.1 C charge/0.25 C discharge after the initial two cycles at 0.1 C charge/discharge. 1 C = 0.55 A. All electrochemical tests are conducted at 30 °C.
