Patent ID: 11961998

Abstract:
Provided is a method of producing multiple particulates, the method comprising: (a) dispersing multiple primary particles of an anode active material, having a particle size from 2 nm to 20 μm, and particles of a polymer foam material, having a particle size from 50 nm to 20 μm, and an optional adhesive or binder in a liquid medium to form a slurry; and (b) shaping the slurry and removing the liquid medium to form the multiple particulates having a diameter from 100 nm to 50 μm; wherein at least one of the multiple particulates comprises a polymer foam material having pores and a single or a plurality of the primary particles embedded in or in contact with the polymer foam material, wherein the primary particles have a total solid volume Va, and the pores have a total pore volume Vp, and the volume ratio Vp/Va is from 0.1/1.0 to 10/1.
