Fabrication of High-Power Li-Ion Hybrid Supercapacitors by Enhancing the Exterior Surface Charge Storage.

The article discusses the fabrication of high-power lithium (Li)-ion supercapacitors (Li-HSCs) from the prospective of single electrodes and devices. It says that magnesium oxide (MnO)-graphene composite (MnO@GNS) was devised as the anode, while three-dimensional (3D) hierarchical porous nitrogen (N)-doped carbon (HNC) was used as the cathode. It states that the hybrid devices with high power and energy density were fabricated by enhancing the exterior surface charge storage.
