Cryogenic storage could enable safe transport of car batteries
Researchers have shown that it's possible to dramatically to reduce the cost of safely transporting damaged electric vehicle batteries by freezing them
As sales of electric vehicles increases, there is more concern for the transportation of damaged and defective lithium ion battery packs. Currently, it is an expensive process, as they are put in an explosion proof box that costs €10,000 and a further €10,000 for the UN accreditation, for which EV manufacturers are picking up the bill.
But now, Researchers from WMG at the University of Warwick in collaboration with Jaguar Land Rover engineers have been able to freeze batteries with liquid Nitrogen.
In the paper, ‘Cycle life of lithium ion batteries after flash cryogenic freezing’ published in the Journal of Energy Storage, researchers highlight that cryogenic freezing does not reduce lithium ion battery’s energy capacity or affect cycle or service life, and could be transported in a safer way.
