  1. While testing ofeis at different depth of dischargeand charge - discharge at different charge - discharge rate reveale that, these material indicate lower conductivity at highcharge - discharge rate, resulting in bad electrochemical perforemence. melting - cooling and inorganic sol - gel were adopted, which facility - simpleand operating - easy, to prepare v _ 2o _ 5 xeroxes as positive material of li - ion battery. the comparision of structual and electrochemical performance between thesecathode materials were investigated for the first time. their electrochemicalbehaviorswerestudiedbygalvanostaticcharge - discharge, cyclicvoltammetry ( cv ), and electrochemical impedance spectroscopy ( eis ) techniques. the results indicte the sample that prepared by melting - cooling revealed moreexcellent performance at low charge - discharge rate, which achieved a high initialdischarge specific capacity of approximate 320 mah ? g - 1

    通過各種充放電測試,循環伏安( cv )曲線以及電化學抗譜( eis )等測試手對材料的電化學性能進行表徵,結果發現,在低倍率放電下,熔融淬冷法合成的材料具有更好的電化學性能, 0 . 1c恆放電至1 . 8v時首次放電容量達320mah ? g - 1 ,並且發現, v _ 2o _ 5作為正極材料組裝成的鋰離子二次電池,除首次循環具有較大的不可容量外,其餘循環可且容量保持能較好, 20次循環后,容量只衰減了6 . 40 % 。
