Abstract
Lithium-ion batteries (LIBs) have become advanced energy storage technologies; however, specific capacity remains limited by the active materials in cathodes. Here, we report Li-LiNO<sub>3</sub> batteries (LNBs) where LiNO<sub>3</sub> in electrolyte serves as both active materials and ion conductor at room temperature. LNBs operate on a highly reversible redox between NO<sub>3</sub><sup>-</sup> and NO<sub>2</sub><sup>-</sup>, which results in an impressive areal capacity of 19 mAh cm<sup>-2</sup> at a plateau voltage of 1.75 V. Furthermore, the pouch cell exhibits stable cycling at a capacity of 100 mAh. This research underscores the potential of LNBs for high-capacity energy storage.
