melting charge
解釋
熔化料-
The difference of reactive mechanisminduced the difference of their structure. v _ 2o _ 5 product prepared by melting - cooling showed more notable undefined structure. after heat - treating under300, particle size becomes smaller, and aggregate to globate grain, showesbetter electrochemical performance at low charge - discharge rate
熔融淬冷法合成的樣品其無定型結構更明顯，前驅體經過300熱處理后，材料的粒徑變細，團聚成球狀的顆粒，球狀特徵更顯著，在低倍率下具有較好的電化學性能。 -
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 ）曲線以及電化學阻抗譜（ eis ）等測試手段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恆流放電至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逆容量外，其餘循環可逆且容量保持能力較好， 20次循環后，容量只衰減了6 . 40 % 。
