1. A highly elastic polymer composite binder composition for use in an anode or cathode of a lithium battery, said composition comprising a polymerizing or cross-linking liquid precursor and a 0.01%-50% by weight of a conductive reinforcement material dispersed in said liquid precursor, wherein said liquid precursor is capable of chemically bonding to an anode active material or cathode active material in said lithium battery upon completion of polymerization or cross-linking reactions to form a high-elasticity polymer and said high-elasticity polymer has a recoverable tensile strain from 5% to 700% when measured without the conductive reinforcement dispersed in said polymer;
wherein said binder composition further comprises a foaming agent or blowing agent dispersed in said liquid precursor.
