The high‐rate capability of solid‐state, rechargeable lithium batteries with sulfide electrolytes is significantly improved when the LiCoO 2 particles are spray‐coated with a Li 4 Ti 5 O 12 film with a thickness of several nanometers (see figure). The power densities of the solid‐state battery with the coated LiCoO 2 are comparable to those of commercialized lithium‐ion cells.
