Understanding how Lithium-ion batteries fail

What happens when lithium-ion batteries overheat and explode has been imaged inside and out for the first time by a team led by UCL PhD student Donal Finegan (UCL Chemical Engineering) and Dr Paul Shearing (UCL Chemical Engineering).

Understanding how Li-ion batteries fail and potentially cause a dangerous chain reaction of events is important for improving their design to make them safer to use and transport.

Hundreds of millions of these rechargeable batteries are manufactured and transported each year as they are integral to modern living, powering mobile phones, laptops, cars and planes. Although battery failure is rare, earlier this year, three airlines announced they will no longer carry bulk shipments of lithium-ion batteries in their cargo planes after the US Federal Aviation Administration tests found overheating batteries could cause major fires.
