▎ 摘　　要

NOVELTY - Composite particulate has a diameter of 10 nm to 50 µm and comprises one or multiple anode-active material particles that are dispersed in a high-elasticity polymer matrix or encapsulated by a high-elasticity polymer shell. The high-elasticity polymer matrix or shell has a recoverable elastic tensile strain not less than 5%, when measured without an additive or reinforcement, and a lithium-ion conductivity not less than 10-8S/cm at room temperature. The high-elasticity polymer comprises a crosslinked polymer network of chains derived from a phosphazene compound. USE - Composite particulate used in anode for lithium-ion battery, lithium metal battery, lithium-sulfur battery, lithium-selenium battery, or lithium-air battery (all claimed). ADVANTAGE - The composite particulate achieves advanced architectures, such as polyphosphazenes with a branched polyphosphazene backbone, supramolecular structures from polyphosphazenes, helical structures with polyphosphazenes, cyclomatrix polyphosphazenes, and dendrimers from hexachloro-cyclotriphosphazene, and achieves absence of chlorine in high yields, and can facilitate the reaction of removing hydrogen chloride. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing multiple composite particulates, which involves dispersing multiple particles of an anode active material in a precursor polymer solution to form a suspension, operating a secondary particle-forming procedure to shape the suspension into multiple droplets and remove the liquid solvent from the droplets, and curing the reactive phosphazene compound to form said composite particulates.
