▎ 摘 要
NOVELTY - Cathode material having formula SiMxCy, is claimed. USE - The cathode material is useful as anode part and cathode part in an electrochemical device of an electronic device (all claimed) i.e. lithium ion battery. ADVANTAGE - The cathode material is capable of further improving the lithium ion battery cycle stability and reducing the lithium ion battery volume expansion. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a cathode part comprising a current collector and the cathode material; and (2) an electrochemical device of an electronic device comprising an anode part and the cathode part
