Abstract
Disclosed are cathode active material (CAM) coated with a lithium carbonate doped with lithium borate with a formula of Li2+xC1−xBxO3 wherein 0<x<0.5 and a preparation method therefor. Also disclosed is a cathode layer comprising the coated CAM in the form of particles. In one embodiment, an all-solid-state battery comprising the cathode layer exhibits improved stability and cycling performance.
Claims29
A coated cathode active material comprising:
- particles of a cathode active material (CAM);
- and
- a coating coated on surface of the particles, wherein the coating comprises a lithium carbonate doped with lithium borate (LCBO) having a formula of Li2+xC1−xBxO3, wherein 0<x<0.5, and wherein the coating has a thickness in a range from 0.5 to 20 nm.
