The data (closed rhombuses) of the Li–SPAN battery cells, sulfurized polyacrylonitrile (SPAN) cathode | carbonate electrolyte solution | Li–metal anode, are for our works. The data (closed circles) of lithium-ion rechargeable batteries (LIBs) are for Panasonic Energy Co., Ltd., LG Chem/LG Energy Solution Ltd., Samsung SDI Co., Ltd., and Contemporary Amperex Technology Co., Limited. The data (open rhombuses and closed squares) of next-generation batteries [lithium–sulfur (Li–S) batteries and lithium–metal batteries (LMBs)] are for Enpower Japan Corp./Enpower Greentech Inc., SoftBank Corp., GS Yuasa Corporation, Sion Power Corporation, Cuberg, SES AI Corporation, and references2,5,21,22,23,24,25,26. An asterisk mark indicates an unstable chg./dischg. performance, the cell energy density is only in the first discharge9. Photographs show the Li–SPAN pouch cell with >750 Wh kg(cell)−1 fabricated in this work.
