Abstract
A method of producing a powder mass for a lithium battery, comprising: (a) mixing an inorganic filler and an elastomer or its precursor in a liquid medium or solvent to form a suspension; (b) dispersing a plurality of particles of a cathode active material in the suspension to form a slurry; and (c) dispensing the slurry and removing the solvent and/or polymerizing or curing the precursor to form the powder mass, wherein at least a particulate comprises one or a plurality of cathode active material particles being encapsulated by a layer of inorganic filler-reinforced elastomer having a thickness from 1 nm to 10 μm, a fully recoverable tensile strain from 2% to 500%, and a lithium ion conductivity from 10S/cm to 5×10S/cm and the inorganic filler has a lithium intercalation potential from 1.1 V to 4.5 V versus Li/Li.
