Abstract
Description
図1は、本実施形態に係るキャパシタ(以下「本キャパシタ」という。)1の構造の断面概略図である。本キャパシタ1は、いわゆる電気化学キャパシタであり、対向して配置される一対の電極2a、2bと、この一対の電極に形成される銅ナノ構造物3と、この一対の電極間に配置される電解質層4と、を有する。一対の電極2a、2bの一方は動作電極であり、他方はこれに対向して配置される対向電極となる。
次に、本キャパシタの充放電方法(以下「本方法」という。)について説明する。本方法は、外部の駆動装置と接続され、一対の電極間に電圧を印加して電荷を蓄積すると共に、短絡する又は逆の電圧を印加することによって蓄積電荷を放出することができる。より具体的に、参照電極(例えば飽和カロメル電極SCE)を用いた場合で説明すると、印加する電圧としては、充電が可能であり、材料の分解電圧を越えない限りにおいて限定されるわけではないが、参照電極SCEに対し負の電位を印加することが含まれている必要があり、好ましくは−2V以上1V以下の範囲の電位とすることが好ましく、より好ましくは−1.5V以上0.75V以下の範囲の電圧とすることが好ましい。
