General maps showing a charge capacities of various anodes and cathodes along with promising battery chemistries that can be formed from their combination. The charge capacities of metallic anodes and oxygen cathodes are their theoretical values, while all other electrodes are reported values in academia as covered in this review. For consistency, all active ion masses for insertion electrodes are assigned to the anode. b Total electrode capacities calculated from a for the aforementioned combinations, plotted against reported discharge voltages as covered in this review. c Cell energy densities calculated from b assuming 50% inactive mass, plotted against reported cycle lives as covered in this review. The faded oval regions represent the general performance of the cell chemistry as reported in academia, while solid rectangular regions represent the performance of commercially available cells [36, 37, 210, 247–256], illustrating the gaps between them
