Electric cars could be charged in a matter of seconds using a revolutionary battery system developed by a team of Scottish scientists, it has been claimed. Researchers at the University of Glasgow have adapted nano-molecules so they are able to store either electric power or hydrogen gas, creating a flexible dual-output battery system. The energy released can take the form of electricity or gas – meaning that the system could be used flexibly in situations that might require fuel or electric power. The team of chemists says the breakthrough could lead to electric cars being charged in seconds, as the nano-molecules can be contained in a pumpable liquid. This could mean that the battery of an electric car could be “recharged” in roughly the same length of time as petrol cars are today, with the old battery liquid being removed simultaneously. The research, published in the journal Nature Chemistry, was led by Professor Leroy Cronin, the University of Glasgow’s Regius Chair of Chemistry.

From battery-powered delivery trucks and rickshaws, to Formula E racing cars, electric vehicles are entering the mainstream. But will a lack of investment in charging infrastructure hold the market back? In 2015 single mum Sushila Devi was struggling to make ends meet and didn’t even have the money to send her three kids to school. However, thanks to low-cost electric vehicle technology, the 30-year-old from the state of Bihar, North East India found a solution. With a loan from a local charity, she bought an e-rickshaw – a type of taxi powered by a three-wheeled electric scooter – and started carrying passengers in her hometown of Bodh Gaya. From rickshaws to buses, cars to delivery lorries, electric vehicles are going mainstream and not just in the richer developed nations. By the mid-2020s, when electric vehicles “will cost the same as ones powered by internal combustion engines”, posing a huge challenge to petrol vehicles. In the meantime, government subsidies are helping to bring down the costs. For example, China – which accounts for half of global electric auto sales – has exempted electric vehicles from purchase taxes since 2014.
