In situ interphase engineering for all-solid-state Li batteries: a case study on the LiNi0.5Mn1.5O4/Li0.33La0.55TiO3 composite cathode guided by ab initio calculations

Doping-induced artificial interphase formation in oxide-based composite cathodes is demonstrated to simultaneously improve sinterability and interfacial stability, which are the main bottlenecks of oxide-based all-solid-state Li batteries.
