氧化锰在中性电解液中的CV曲线？ 看看这篇文章，Materials for electrochemical capacitors，里面有详细讲解。 这篇文章我看了好多遍，但是都没有说是为什么？The charge storage mechanism is based on surface adsorption of electrolyte cations C+ (K+, Na+…) as well as proton incorporation according to the reaction: MnO2 + xC+ + yH+ + (x+y)e– ? MnOOCxHy (8) Figure 6 shows a cyclic voltammogram of a single MnO2 electrode in mild aqueous electrolyte; the fast, reversible successive surface redox reactions define the behaviour of the voltammogram, whose shape is close to that of the EDLC. MnO2 micro-powders or micrometre-thick films show a specific capacitance of about 150 F g–1 in neutral aqueous electrolytes within a voltage window of 1 V，查看更多
