Hybrid super capacitors by researchers store 4-6 times more energy

Even though batteries used in electric cars have advanced in performance significantly over the years and more so recently, but it still leave some gaps in performance due to some of the inherent problems of batteries such as longer charging time, life of the battery (irrespective of its usage are not), and charge and discharge cycles. On the other side a little different supercapacitors/ultracapacitor technology has even more technical issues for using them to store energy in electric cars. The biggest issue with the supercapacitors is they store less energy compared to batteries and the stored energy dissipates faster compared to batteries while the capacitors are idle. The researchers working on increasing the energy density by increasing the surface area of metal plates and also using a dielectric material to increase the capacitance. Graphene is very well employed as a metal layer. Below are some of the latest achievements in the super capacitor area: Researchers at California NanoSystems Institute have developed a super capacitor which offers features of both a battery as well as a super capacitor. The super capacitor developed by California NanoSystems Institute Store six times more energy than the presently available commercial super capacitors in the market. The concept used by these researchers is, they could able to increase the contact area between the el...
