V（III）取代方解石FeBO 3基质中的Fe（III）以降低充电/放电电压并增加理论容量。VBO 3的平均充放电电压比FeBO 3低1V，可逆容量为420 mAh/g。为了研究硼酸盐阳极的特性，测量了X射线Rietveld，XPS和XAFS剖面。为了进一步提高VBO 3的阳极性能，使用具有低温软化点的萘基各向同性沥青涂覆碳涂层。
V(III) was substituted in place of Fe(III) in the calcite FeBO3matrix to reduce the charge/discharge voltage and increase the theoretical capacity. The mean charge/discharge voltage of the calcite VBO3was 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.
