▎ 摘　　要

NOVELTY - Cathode material comprises active material including crystalline silicon (11) and amorphous silicon (12), where the crystalline silicon is provided with a hole, and the hole is distributed with the amorphous silicon. USE - The cathode material is useful in lithium-ion battery (claimed). ADVANTAGE - The cathode material has high first effect, high reversible capacity and high anti-expansion performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing cathode material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the cathode material for lithium-ion battery. 11Crystalline silicon 12Amorphous silicon
