They posses a high surface area for better electron transfer, which can lead to the improved performance of an electrode in an electric double capacitor or battery.
The high surface electrode material, also called Double Layer Capacitor (DLC), is least costly to manufacture and is the most common.
高表面电极材料,也被称为双电层电容器(金刚石),是生产成本最低,是最常见的。

The paper also found that the positive carbon electrode was much smaller than that of negative one, so it urged to develop new positive material to make up hybrid capacitor.
