文摘

Mo(VI) and W(VI) substituted Li_n+xMo_yV_3−yO₈ and Li_n+xW_yV_3−yO₈, where y≤0.25, were synthesized by solid state reactions. Lithium insertion in these phases from organic electrolytes during electrochemical reaction was investigated. Oxides of the composition Li_n+xMo_yV_3−yO₈ with a molybdenum content in the structure near the upper concentration limit (0.2≤y<0.25) exhibit high discharge capacities. For the strongly crystalline Li_1+xV₃O₈-like host structure (x
