Research Abstract |
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.
