Titanium Carbide Graphene Hybrid Supercapacitor Match NiMh Battery Energy Density. Batteries store large amounts of energy but are slower to discharge energy. Supercapacitors can only store about one-tenth of the energy of a battery but are quicker at discharging it. They are used as a secondary power supply in devices such as smartphones, cameras and laptops, and have a far longer cycle life.
