石(shi)墨(mo)烯(xi)基碳材料是一種有前(qian)景的(de)電(dian)(dian)極材料用于雙電(dian)(dian)層(ceng)（EDL）電(dian)(dian)容器，因此理(li)解(jie)(jie)石(shi)墨(mo)烯(xi)/電(dian)(dian)解(jie)(jie)質界面的(de)結構(gou)和性質引發(fa)了極大的(de)研究興趣。?這里，電(dian)(dian)化(hua)學阻抗光譜（EIS）和電(dian)(dian)化(hua)學石(shi)英晶體微(wei)量(liang)天平（EQCM）用于表征單層(ceng)石(shi)墨(mo)烯(xi)在(zai)離子(zi)(zi)液體（EMI-TFSI）電(dian)(dian)解(jie)(jie)質中的(de)離子(zi)(zi)通量(liang)與(yu)吸(xi)附。?該(gai)工作發(fa)現，在(zai)正極化(hua)和負極化(hua)期間，一個帶正電(dian)(dian)的(de)離子(zi)(zi)種類(lei)解(jie)(jie)吸(xi)和離子(zi)(zi)重(zhong)組(zu)分(fen)別主導了雙電(dian)(dian)層(ceng)充電(dian)(dian)過程，致使(shi)EDL電(dian)(dian)容隨著(zhu)施加電(dian)(dian)勢增(zeng)加而增(zeng)加。…
