Summary:Recent advances in producing and fabricating a range of nanostructured carbons and ionic liquid-based electrolytes have shown the feasibility of combining the power density of supercapacitors and the energy density of rechargeable batteries. The resulting cells work in a very similar way to electrostatic double-layer capacitors but use different carbon and electrolyte materials that are not only safer and easier to recycle at the end of life, but also enable the devices to operate at higher voltages, resulting in higher energy densities. Featuring higher energy densities than those presented by conventional supercapacitors, and with charging rates 10 times faster than current superchargers, the extreme fast charging cells can be used either on their own or in combination with lithium-ion batteries for a range of applications—such as storing energy rapidly in EVs and their charging stations. If an EV is slow-charged over an eight-hour period, then a single charge point can only be used by three vehicles a day. [...]in order to support 19 million EVs, the UK would need an astounding number of charge points: 6.3 million.
