Photocharging of high-potential spinel LiMnO is demonstrated by using a water-in-salt electrolyte and TiO nanoparticles. In a developed half-cell system with an electron acceptor, Li extraction from LiMnO proceeds under the illumination of UV-visible light at an estimated rate of c.a. 23 mA g. This work paves the way for highpotential cathode materials in photo-rechargeable batteries.
