▎ 摘　　要

NOVELTY - The material has an acetylene black part formed with an aluminum foil part that is coated with a coating film. A button cell electrode piece is formed with the coating film. Titanium acid lithium precursor is formed in a tubular furnace. A glove box is formed with an active material. A microwave reactor mixes titanium source solution to lithium source solution. USE - Graphene/lithium titanate composite material. ADVANTAGE - The material has high capacity, and allows the aluminum foil part formed on the coating film and the active material that are coated on a semi-battery so as to improve charging-discharging performance.
