高電壓超級電容器技術 2023/07/11

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2.5-2.8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。

Electrical Double-Layer Capacitors (EDLCs) are limited by relatively low cell voltage, with a maximum voltage of 2.5 - 2.8 V in organic liquid electrolytes. MMSL has developed a machine where graphene nanowall electrodes (GNW/N-doped GNW) are directly grown vertically to create binder-free supercapacitors. The positive and negative electrodes provide a wide potential window up to 4.0 V and have better voltage tolerance compared to current activated carbon electrodes.
