Abstract
Provided is a lithium battery anode electrode comprising multiple particulates of an anode active material, wherein at least a particulate comprises a plurality of porous particles of anode active material having a pore volume Vpp and a solid volume Va, an electron-conducting material as a non-porous matrix, binder or filler material (containing no porous carbon matrix or carbon foam), and additional pores having a volume Vp which are encapsulated by a thin encapsulating layer of an electrically conducting material, wherein the thin encapsulating layer has a thickness from 1 nm to 10 μm, an electric conductivity from 10S/cm to 20,000 S/cm and a lithium ion conductivity from 10S/cm to 5×10S/cm and the volume ratio Vp/Va in the particulate is from 0.1/1.0 to 10/1.0 or (Vpp+Vp)/Va is from 0.3/1.0 to 20/1.0.
