Hard carbon negative electrode material for lithium-ion batteries

Electrochemical properties of surface-modified hard carbon

Current methods for improving the electrochemical properties of lithium-ion battery electrode materials demand an understanding of its surface property and chemistry. We investigate the electrochemical property of a thin-film Li 4 Ti 5 O 12 (LTO) layer on a hard carbon (e.g., glass-like carbon) ideal model electrode and propose that its unique properties make it
