Li-dedoped beta rhombohedral boron (・-B), which has different structure with Li-doped ・-B, was synthesized by the heat treatment of Li-doped ・-B at 600 and 800 ℃. Especially, it was found that Li was successfully dedoped with keeping the removal of interstitial B for Li7・-B obtained by the heat treatment at 600 ℃ and the hole doping was indicated. It was also found that V removes by electrochemical Li doping into V doped ・-B.

通过对掺锂β-B在600和800 ℃热处理，合成了与掺锂β-B结构不同的脱锂β-菱面体硼（·-B）。特别是600 ℃热处理后的Li 7·-B，在保持间隙B去除的同时，Li被成功地脱掺杂，表明存在空穴掺杂。同时还发现V通过电化学Li掺杂到V掺杂的·-B中而被去除。
