Effect of PVP Coating on LiMnBO Cathodes for Li-Ion Batteries.

LiMnBO is a potential cathode for Li-ion batteries, but it suffers from a low electrochemical activity. To improve the electrochemical performance of LiMnBO, the effect of polyvinyl pyrrolidone (PVP) as carbon additive was studied. Monoclinic LiMnBO/C and LiMnBO-MnO/C materials were obtained by a solid-state method at 500 °C.
