簡介 Introductions
超級電容器受限於電壓不足，於有機電解液系統電壓可達2.5-2.7伏特。透過機械所自行開發的機台製作，以直接垂直成長石墨烯奈米壁電極（無摻雜與氮摻雜）製作無須接著劑之超級電容系統，正極與負極分別提供廣泛的電位窗至4.0伏特。相對於目前的活性碳電極可以達到更佳的電壓耐受性。
The low cell voltage (2.5 - 2.7 V in organic liquid electrolytes) of Electrical double-layer capacitors (EDLCs) encounter the issue of a relatively low energy density. The binder-free, vertically grown graphene nanowalls (GNW/N-doped GNW). This newly designed asymmetric EDLC exhibits a cell voltage of 4 V. Materials with an inert surface enable to tolerate a wider potential window in commercially available organic electrolytes in comparison with activated carbons (ACs).
