摘要: The capacity of natural graphite in the lithium ion battery anode decays seriously. phenol resin is used as a reaction material to modify electrochemical performance spherical batteries. Measuring reversible indicates change surface structure graphite. A dense layer methyl groups was thus formed. Some structural imperfections are removed and stability increased. Clearly, reducing irreversible beneficial controlling uniformity structure.
