A High Performance Lithium-Ion Capacitor with Both Electrodes Prepared from Sri Lanka Graphite Ore

The natural Sri Lanka graphite (vein graphite) is widely-used as anode material for lithium-ion batteries (LIBs), due to its high crystallinity and low cost. In this work, graphitic porous carbon (GPC) and high-purity vein graphite (PVG) were prepared from Sri Lanka graphite ore by KOH activation, and high temperature purification, respectively. Furthermore, a lithium-ion capacitor (LIC) is fab...

Reduced graphite oxide in supercapacitor electrodes.

The current energy needs have put the focus on highly efficient energy storage systems such as supercapacitors. At present, much attention focuses on graphene-like materials as promising supercapacitor electrodes. Here we show that reduced graphite oxide offers a very interesting potential. Materials obtained by oxidation of natural graphite and subsequent sonication and reduction by hydrazine ...

Nanostructured Vanadium Oxide Electrodes for Enhanced Lithium-Ion Intercalation

Intercalation-electrode materials are electroactive and serve as host solids into which guest species are reversibly intercalated from an electrolyte. Currently there are three intercalation materials that are used commercially as positive-electrode materials in lithium-ion rechargeable batteries: LiCoO2, LiNiO2, and LiMn2O4. LiCoO2 is the most popular among the possible cathode materials becau...
