Enhancement of the High‐Rate Capability of Solid‐State Lithium Batteries by Nanoscale Interfacial Modification

The high-rate capability of solid-state, rechargeable lithium batteries with sulfide electrolytes is significantly improved when the LiCoO2 particles are spray-coated with a Li4Ti5O12 film with a thickness of several nanometers (see figure). The power densities of the solid-state battery with the coated LiCoO2 are comparable to those of commercialized lithium-ion cells.
