充放电电压与材料的能量密度计算问题?请问各位大牛,我这里有一个问题没有搞明白,还请高人指点。一篇文章中:The overall capacity of Na full cell using our advanced cathode and anode can reach 175 mA h g1 (considering the weight of cathode and anode materials). The operation discharge voltage is on average 2.5 V. As a result, the total energy density for this Na full cell is as high as 430 W h kg1。这是文章中的原话(Chem. Commun., 2015, 51, 4693--4696)。问题是这里的放电电压是怎么从充放电曲线上得出来的?我一直整不明白。 谢谢 原文章中的充放电曲线图如下: QQ截图20150721140059.png查看更多2个回答 . 12人已关注
