  "textContent": "Provided is an anode active material layer for a lithium battery. This layer comprises multiple particulates of an anode active material, wherein at least a particulate is composed of one or a plurality of particles of an anode active material being encapsulated by a thin layer of graphene/elastomer composite having from 0.01% to 50% by weight of graphene sheets dispersed in an elastomeric matrix material, wherein the encapsulating shell (the thin layer of composite) has a thickness from 1 nm to 10 μm and the graphene/elastomer composite has a lithium ion conductivity from 10S/cm to 10S/cm and an electrical conductivity from 10S/cm to 100 S/cm when measured at room temperature. The anode active material is preferably selected from Si, Ge, Sn, SnO, SiO, CoO, MnO, etc., which has a specific capacity of lithium storage greater than 372 mAh/g (the theoretical lithium storage limit of graphite).",
