Electric vehicles have one sore point about them – they come with big, heavy and expensive batteries, even though they do a pretty good job in helping save the environment. Well, Volvo aims to change than by coming up with body panels that double up as car batteries as well. Now that’s an interesting thought, but a painful one as well if you take into consideration the hassles of getting into an accident, only to see your car’s batteries all smashed up at the same time. The Swedish vehicle manufacturer is currently collaborating with the Imperial College in London on a materials development project which could eventually turn your entire vehicle into an ultra-light battery running on all four wheels. A visible result should come much later on, with at least three years’ worth of buffer so don’t get too excited just yet.
