Abstract

Aspects of the disclosure include systems and methods for manufacturing thermally stable nickel-rich cathodes. An exemplary method can include providing an active material including a plurality of active material particles. The plurality of active material particles include nickel. A nanoparticle slurry additive having a plurality of nanoparticles is provided. The plurality of nanoparticles include one or more of a thermally stable olivine type material, a thermally stable spinel type material, and a thermally stable manganese-nickel dioxide type material. The method includes forming a slurry by mixing the active material and the nanoparticle slurry additive. The plurality of nanoparticles form a thermal inhibitor layer on and in direct contact with a surface of the plurality of active material particles. A free-standing electrode film is formed by calendering the slurry and the free-standing electrode film is laminating to a current collector to define a thermally stable nickel-rich cathode.
