▎ 摘　　要

NOVELTY - The method involves mixing lithium carbonate with silicon dioxide. Ferrous oxalate is added. Ball milling process is performed. Lithium iron silicate precursor powder is added during ball milling. Mass ratio of sucrose to sepiolite powder is 2: 1. The sucrose and deionized water are added into saturated sucrose solution that absorbs the sepiolite powder. A graphene-like precursor is heated. The lithium iron silicate precursor powder is obtained. The lithium iron silicate precursor powder is mixed with the graphene-like precursor. USE - Graphene oxide doped lithium ion battery lithium iron silicate composite anode material preparation method. ADVANTAGE - The method enables increasing electric conductivity of lithium iron silicate anode material and realizing higher energy density. DESCRIPTION OF DRAWING(S) - The drawing shows a graph illustrating a graphene oxide doped lithium ion battery lithium iron silicate composite anode material preparation method.
