A battery capable of being charged in seconds to power electric cars has been developed at the University of Glasgow. Researchers have created a prototype that uses a metal oxide, an “exotic rust”, that can be charged with electricity when added to water. Lee Cronin, one of the research team, said that the development could hold the key to turning electric cars, which can take hours to charge, into a viable challenger to petrol and diesel vehicles. “This will overcome a big kind of cultural inertia,” he said. “You can get instant refuel in the same way, with no change to your behaviour now. Because it’s a liquid it would just work as normal using the same infrastructure. It will certainly be a game-changer if we can make sure that the prototype scales up as we expect.” Drivers would remove the spent liquid using one nozzle at a garage forecourt pump, then use a second nozzle to refill the battery. The Glasgow team said that a tank of the liquid would provide the same range as conventional fossil fuels. Professor Cronin told BBC Scotland that his rust battery did not degrade in the same way as present electric systems and that its capacity was higher. The team said that making the liquid was not too difficult.

Electric cars are gaining prevalence and will continue to do so over the coming decade. With the condemnation of diesel, worries of petrol car CO2 emissions and a notable shift by manufacturers to alternatively fuelled cars, numbers of these vehicles on UK roads will continue to climb. Despite over 26 per cent growth in registrations in July compared to last year, EVs only represent a very small margin of total cars on the roads in the UK. In 2013 there were around 3,500 electric cars registered on the road in Britain, which has now risen to over 140,000. There are, however, many reasons why drivers could save money over time by owning an electric car. Currently, electric cars typically cost more money than petrol or diesel equivalents and the smaller and cheaper electric cars have short range. For example, the Renault Zoe start at £18,420 and has range between 124-miles and 186-miles depending on the model. New research has also suggested that drivers could save huge amounts of money when it comes to refuelling a car by switching to electric. According to research by Vivid Economics for WWF claim that motorists that drive a petrol car spend around £800 a year on fuel. The study estimates that on average an electric car owner will spend £170 to keep their vehicle topped up at home by 2030. In addition to this, drivers could also save an additional £70 a year by taking advantage of ‘smart charging.’ Smart charging refers to drivers taking advantage of charging at periods of low demand, such as overnight.
