Without that capacity, it will have to source heavy batteries from abroad, which is likely to make UK car production uncompetitive and result in costly tariffs.
Another factor is the technological future of car batteries. Research is being done into lighter battery packs and if their development is not kept up to date, British-made cars will fall behind the competition.
Britain lags behind many European countries in building large car battery factories. Nissan owns a 1.7 gigawatt-hour facility that supplies the needs of its Sunderland production line for the all-electric Leaf model. It is planning another, larger plant to enable the electrification of more of its models.
But automakers like Jaguar Land Rover, Aston Martin, Mini, Vauxhall and smaller brands like Lotus, Bentley and Rolls-Royce will all need locally made batteries.
Another major development is planned in the vicinity of Coventry Airport, with the support of the City Council and the airport owners.
It plans to launch up to 60 gigawatt-hour batteries starting in 2025, although no customers are yet to be announced.
The region is also home to the Advanced Propulsion Center and the UK Battery Industrialization Centre, agencies researching electric car technology and production.
Britishvolt is building a large gigafactory in Blyth, Northumberland, which will produce up to 30 gigawatt hours.
