▎ 摘  要

NOVELTY - The method involves mixing active materials, carbon additives, and polymer binders to form a slurry mixture. The slurry mixture is deposited on a substrate. A coating is formed. The coating is dried. Energy is applied to the dried coating. Carbon additives are chemically functionalized or mixed with surfactants. The carbon additives are de-functionalized. The surfactants are carbonized as a result of the application of energy. The polymer binders are carbonized as a result of the application of energy, where the carbon additives comprise carbon nanotubes, graphene, grapheme oxides, graphene nanoplatelets, carbon nanofibers, and graphite. USE - Method for manufacturing a lithium battery electrode. ADVANTAGE - The method enables providing lithium-ion battery with excellent cycle characteristics, stability, cycle characteristics and cycle characteristics. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating a functionalization and de-functionalization method.
