NOVELTY - Carbon-coated modified carbon/silicon oxide composite electrode material comprises a porous carbon/silicon oxide core-shell coated with carbon material. USE - Used as carbon-coated modified carbon/silicon oxide composite electrode material. ADVANTAGE - The material improves electrode capacity through the reasonable mixing of carbon/silicon oxide component, the first discharge capacity can reach 950 mAh/g or more, the first (second circle) coulomb efficiency is more than 90%, the capacity retention rate after 300 cycles of charging and discharging under the current 500 mA/g more than 85%. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a lithium-ion battery, comprising the electrode.
