▎ 摘　　要

NOVELTY - Composite particulate comprises one or more than one anode active material particles that are dispersed in a high-elasticity polymer matrix or encapsulated by a high-elasticity polymer shell. The composite particulate has a diameter from 10 nm to 50 µm. The high-elasticity polymer matrix or shell has a recoverable elastic tensile strain no less than 5%, when measured without an additive or reinforcement dispersed, and a lithium ion conductivity no less than 10-8S/cm at room temperature. The high-elasticity polymer comprises a polymer derived from a monomer selected from vinyl sulfite, ethylene carbonate, methyl methacrylate, vinyl acetate, fluorinated monomers having unsaturation for polymerization, sulfones, sulfides, nitriles, sulfates, siloxanes, and silanes. USE - Composite particulate for use in anode for lithium battery, such as lithium-ion battery, lithium metal battery, lithium-sulfur battery, lithium-selenium battery, or lithium-air battery (all claimed). ADVANTAGE - The composite particulates when used as an anode active material in lithium battery, enables a lithium battery to exhibit a high cycle life, high reversible capacity, low irreversible capacity, small particle sizes (for high-rate capacity), and compatibility with commonly used electrolytes. The production method can readily and easily produce such composite particulates in large quantities. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: a. an anode, which comprises multiple composite particulates as an anode material; b. a method for producing the anode, which involves: i. dispersing multiple particles of an anode active material and a conductive additive in a precursor polymer solution to form a suspension where the precursor solution comprises at least a curing agent dissolved or dispersed in a reactive liquid medium that comprises a monomer or oligomer; ii. dispensing and depositing a layer of the suspension onto a solid substrate surface; and iii. curing the monomer or oligomer to form the anode; c. a lithium battery, which comprises anode, a cathode, and an electrolyte in ionic contact with the anode and the cathode; and d. a method for manufacturing multiple composite particulates, which involves: i. dispersing multiple particles of an anode active material in a precursor polymer solution to form a suspension where these particles are fully embedded or immersed in the precursor solution; ii. operating a secondary particle-forming procedure to shape the suspension into multiple droplets and remove the liquid solvent from the droplets; and iii. curing the monomer or oligomer to form the composite particulates where particulate comprises one or multiple anode active material particles that are dispersed and embedded in a polymer matrix or encapsulated by a polymer shell.
