超电容 三电极测试讨论功率密度到底有无意义??Design and Synthesis of MnO2/Mn/MnO2 Sandwich-StructuredNanotube Arrays with High Supercapacitive Performance forElectrochemical Energy Storage 看了这篇nanoletter的文章,我觉得他计算功率密度的相当有问题啊,你看他的公式,如果把C代入energy density,然后再代入power density,得到的结果是power density=1/2I⊿V÷m,就是电流密度乘电压窗口,这和活性材料有个啥关系啊我看别人的paper上算功率密度的是=P=V2/4RsRs是等效电阻,这才对啊这个paper也太假了吧,还是我理解不对where I is the charge/discharge current,w is the mass of the active electrode material,查看更多
