Abstract
The present invention provides a thermally-decomposable consolidated polymer particle encapsulated-electrode for a lithium-ion battery. The electrode includes polymer particles including at least one connection unit and at least one crosslinker in an amount of approximately 40% to 98% by weight and at least one binder material in an amount of approximately from 2% to 60% by weight. The consolidated crosslinked polymer particle coating results in a porous structure encapsulating the electrode. The pressure resistance of the consolidated crosslinked polymer particle coating ranges approximately from 0.5 to 8 MPa and the consolidated crosslinked polymer particle coating is decomposed to release a non-flammable gas and phosphorous-containing molecules so as to prevent thermal runaway at a temperature approximately from 300° C. to 500° C.
