A composite particulate for a lithium battery, wherein the composite particulate has a diameter from 10 nm to 50 μm and comprises one or more than one anode active material particles that are dispersed in a high-elasticity polymer matrix (forming a continuous material phase) or encapsulated by a high-elasticity polymer shell, wherein the high-elasticity polymer (matrix or shell) has a fully recoverable tensile strain no less than 5%, when measured without an additive or reinforcement dispersed therein, and a lithium ion conductivity no less than 10−8 S/cm at room temperature and wherein the high-elasticity polymer comprises a crosslinked network of chains from at least one polymer containing carboxylic and/or hydroxyl groups.
