文摘

Mesocarbon microbeads (MCMB) powders were treated in Ar–H₂–SF₆ radio frequency inductively coupled thermal plasma. The structure, chemical composition and related electrochemical property changes have been studied. The results demonstrated that the active surface area has a great influence on the electrochemical properties of MCMB powder, and the specific irreversible capacity loss decays non-linearly with the increase of active surface area.
