Cathodal materials for lithium cells

摘要

A cathodal material for lithium cells comprises a porous lithium oxide microparticle is provided. The porous lithium oxide microparticle comprises a plurality of porous lithium oxide nanoparticles formed with a first conductive layer therein, a pore defined by connecting the lithium oxide nanoparticles, a second conductive layer covering at least a surface of one of the lithium oxide nanoparticles contacting the first conductive layer and forming a three-dimensional conductive network between the lithium oxide nanoparticles, and a conductive fiber connecting with the second conductive layer.
