The collapse of Britishvolt, with the loss of nearly 300 jobs, is the bitter end of an inglorious effort by both the company and the UK government to establish a homegrown automotive battery maker.

Created at the end of 2019, Britishvolt hoped to mirror the success of Sweden’s Northvolt. What followed was a series of false starts and unfulfilled promises that slowly exposed the unedifying truth at the heart of the Britishvolt enterprise: it lacked production-ready battery technologies or mainstream automotive customers.
