USE - Thermally-decomposable consolidated polymer particle encapsulated-electrode for use in lithium-ion battery (claimed). ADVANTAGE - The thermally-decomposable consolidated polymer particle encapsulated-electrode has improved safety of the battery and is able to avoid thermal runaway at a temperature approximately from 300-500degrees Celsius. DETAILED DESCRIPTION - Thermally-decomposable consolidated polymer particle encapsulated-electrode has electrode selected from a cathode including a lithium-based material selected from lithium manganese oxide (LMO), lithium cobalt oxide (LCO), lithium nickel manganese cobalt oxide (NMC), and lithium iron phosphate (LFP), or an anode selected from graphene, graphite, lithium titanate (LTO), a silicon compound, a silicon carbon composite, a tin-containing compound, and a tin-based composite. The consolidated crosslinked polymer particle coating forming a porous structure encapsulating the electrode. The consolidated crosslinked polymer particle coating comprises a multiple polymer particles including connection unit and at least one crosslinker. The connection unit and crosslinker have cyclic compound analogue structure including non-flammable gas unit and phosphorous-containing unit. The binder material in an amount of 2-60 wt.%. The polymer particle in an amount of 40-98 wt.%. The crosslinker in an amount of 5-50 wt.% based on the polymer particle. The diameter of the polymer particle is 0.05-8 microm. The pressure resistance of the consolidated crosslinked polymer particle coating range is 0.5-8 megapascal. The consolidated crosslinked polymer particle coating is decomposed to release a non-flammable gas and phosphorous-containing molecules to prevent fire and thermal runaway at a temperature approximately from 300-500degrees Celsius.
