▎ 摘　　要

NOVELTY - Preparing oxidized tin-based composite material involves preparing composite ball from graphene and polystyrene microsphere which is then dispersed in surface active agent solution. The solvent is evaporated to give composite granule film. The composite film is then mixed with tin oxide sol and sintered to obtain oxidized tin-based composite material. The tin oxide sol contains iron and tin. USE - Method for preparing oxidized tin based composite material (claimed). ADVANTAGE - The oxidized tin-based composite material reduces the irreversible capacity of lithium ion battery.
