Abstract
Description
Csp=Qm/ΔV (1)
Csp=IΔt/ΔVw (2)
QmはCVから積分した特定ボルタンメトリー電荷(Mn酸化物量に基づく)であり、ΔVは走査範囲(すなわち0.8V×2)であり、Iは加えた電流密度(2A/g)であり、wはMn酸化物の量であり、Δtは放電サイクル期間である。2つの電極系に基づく充放電曲線により、Cspは対称スーパーキャパシタの比容量であり、エネルギー密度(E)と出力密度(P)は方程式(3)と(4)に基づき、時間−電位曲線から計算する。
E=1/2CspΔV2 (3)
P=E/Δt (4)
Δtは放電時間であり、ΔVは電池電圧(すなわち2.0V)である。
