Benefiting from the high-energy-density Li₂O-based cathode and ultra-stable ether-based electrolyte system, we report a low-cost and high-energy-density 500 Wh/kg_-cell Li-metal pouch cell driven by pure anionic redox activity. The non-superoxo/O₂ “safe” charge depth has been extended to 750 mAh/g∼Li₂O. Fairly taking the entire cathode mass loading (including inactive components) into calculation, a specific capacity of 477.3 mAh/g can be achieved. The cost/price of cathode catalytic matrix has been efficiently controlled by the employment of low-cost Ni-based catalyst substrate. Benefitting from the electrolyte modification, highly efficient and long-term stable Li-metal cycling guarantees the employment of limited Li metal in full-cell systems, which largely boosts the pouch-cell-level energy density. Finally, by explicitly sharing and analyzing the promoting space of each cell-level parameter in the current pouch-cell system, we want to pass a straightforward message to battery researchers, directing their attention to the development of this promising low-cost and high-energy-density cell system.
