 The lithiation slash dilithiation properties of alpha, C3N4 and beta, C3N4 are compared and the carbon coating effects are examined. Then, beta, Si3N4 at various fractions is used as the secondary phase in a C-anode to modify the electrode properties. The incorporated beta, C3N4 decreases the crystal size of C and introduces a new NCO species at the beta, C3N4 slash C interface. The nitrogen from the milled beta, Si3N4 diffuses into the surface carbon coating during the carbonization heat treatment, forming parolic nitrogen and CNO species. The synergistic effects of combining beta, C3N4 and C phases on the specific capacity are confirmed. The operand x-ray diffraction and x-ray photoelectron spectroscopy data indicate that beta, C3N4 is partially consumed during lithiation to form a favorably 3N species at the electrode. However, the crystalline structure of the hexagonal beta, C3N4 is preserved after prolonged cycling, which prevents electrode agle.
