Light-induced Li extraction from LiMn $_{2}$ O $_{4}$ /TiO $_{2}$ in a water-in-salt electrolyte for photo-rechargeable batteries

Shimokawa, Kohei*; Matsubara, Shogo*; Okamoto, Akihiro*; Ichitsubo, Tetsu

Photocharging of high-potential spinel LiMn $_{2}$ O $_{4}$ is demonstrated by using a water-in-salt electrolyte and TiO $_{2}$ nanoparticles. In a developed half-cell system with an electron acceptor, Li extraction from LiMn $_{2}$ O $_{4}$ proceeds under the illumination of UV-visible light at an estimated rate of c.a. 23 mA g $^{-1}$ . This work paves the way for highpotential cathode materials in photo-rechargeable batteries.
