ZnO/ZnS/Carbon Nanocomposite-Derived Sulfur-Doped carbon nanosheets using a layered nanoreactor: Towards advanced supercapacitor electrodes and devices

Various approaches have been applied to increase the capacity of electric double layer capacitors (EDLC) by increasing the accessible surface area of the electrode material (mainly carbon) for electrolyte ions. One method is to make the active material particles smaller or use graphite-based carbon...
