Batteries are powering the electric car revolution, but can we make them longer lasting, faster charging and smaller and lighter? Beyond electric cars and other vehicles, the more applications means more renewable energy can be stored and used, driving us away from fossil fuels. Tom Heap visits UKBIC - the UK Battery Industrialisation Centre in Coventry - a vast facility to develop better batteries. He dons full protective gear to see some of the processes involved in making batteries and testing new chemistries and engineering. He speaks to Isobel Sheldon from British Volt about the goals and potential that could be realised by improving batteries and climate scientist Dr Tamsin Edwards assesses how much carbon dioxide this could potentially save.
