Abstract

V(III) was substituted in place of Fe(III) in the calcite FeBO₃ matrix to reduce the charge/discharge voltage and increase the theoretical capacity. The mean charge/discharge voltage of the calcite VBO₃ was 1V lower than that of FeBO₃, and the reversible capacity was 420mAh/g. To investigate the characteristics of borate anodes, the X-ray Rietveld, XPS and XAFS profiles were measured. To further improve the anode performance of VBO₃, a carbon coating using a naphthalene-based isotropic pitch with a low-temperature softening point was applied.
