Lithium ion batteries are used in a wide range of applications and technologies. As it happens; if you are reading my blog on a smartphone, laptop or tablet, you are probably holding one right now. From mobile phones to electric cars, Li-ion batteries are all around us, but how do we make sure they are safe?
As I have remarked previously in my blog ‘Bulletproof batteries‘, there are significant safety issues associated with Li-ion batteries. In 2013, a problem with overheating batteries forced airlines to ground their Boeing 787 ‘Dreamliner’ aircraft, after reports of batteries bursting into flames.
The use of Li-ion batteries is becoming more wide-spread. So we need to gain a better understanding of the hazards and risks associated with their use.
That’s why a research group led by chemical engineers from University College London (UCL) UK, with the European Synchrotron (ESRF), Imperial College London and the National Physical Laboratory, have been working to figure out what happens to Li-ion batteries when they overheat and explode.
