a Galvanostatic discharge–charge profiles of the Li–CO2 battery with quinary-molten salt electrolyte at different current densities from 1.0 to 20.0 A g−1 at 150 °C. b Plots of discharge–charge overpotential measured at 500 mAh g−1 as a function of current density. c Plots of operating voltage and power density versus current density of the Li–CO2 battery at 150 °C with scan rate of 0.01 mA s−1. d Galvanostatic discharge–charge profiles of a Li–CO2 cell with 2.0 A g−1 current density over up to 100 cycles.
