▎ 摘　　要

NOVELTY - A composite electrode material consists of an electrode material inner core (201) and an organic fiber coating layer (202) compounded on the surface of the electrode material inner core through a bonding. The coating layer contains organic fibers containing an amide bond and/or a carbon-nitrogen bond, and a benzene ring structure. USE - Composite electrode material is used for manufacturing lithium battery for electronic device (all claimed) e.g. consumer electronic product. Can also be used for electric vehicle, electric ship, and electric tool. ADVANTAGE - The composite electrode material has reduced volume expansion property, due to high strength and low tensile strain of the organic fiber coating layer, and suppressed occurrence of plastic deformation, and provides battery with excellent cycle stability and electronic product with excellent durability and safety performance, while improving the cavity space for key components such as chips and circuit boards, reducing the proportion of battery in the internal cavity of the electronic device, and preventing the occurrence of battery bulge and warpage of back cover, after a long cycle. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: preparation of the composite electrode material; lithium battery; and electronic device. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of composite electrode material. 200Composite particle 201Core 202Coating layer
