Cage Effect of Nitrogen Oxide Radicals Enables Li-NO_x Cell with a 3.8 V Cell Voltage.

ABSTRACT: The utilization of redox-active gas as cathode materials has been proposed as a promising approach to meet the demand for next-generation battery technologies. Toward this end, nitrogen oxides (NO_x)-inexpensive, abundant gases readily produced from ammonia on an industrial scale-is a promising energy storage media; however, its utilization as cathode material has not been achieved. In this work, the cage effect of NO and NO₂ radicals are utilized to stabilize the charge product of Li-NO_x cell as N₂O₃. This cell operates via reversible redox of LiNO₃ to N₂O₃, achieving a specific capacity of 1,570 mA h g_carbon ^-1 or 25 mA h cm_electrode ^-2 at a full cell voltage
