COATING FOR ELECTRODE ACTIVE MATERIALS, ELECTRODES, AND ELECTROCHEMICAL CELLS THEREOF

Coated cathode active materials include a cathode active material that is coated by a hydroxide-containing material, such as a metal hydroxide. The coated cathode active materials may be incorporated into electrochemical cells, including solid-state batteries. Electrochemical cells including the coated cathode active materials have improved capacity retention as compared to electrochemical cells including un-coated cathode active materials.
