The company claims it already produces six percent of the world's rechargeable batteries for its vacuum cleaners.

James Dyson has shed more light on his ambitious EV project, promising to achieve something 'radical' without help from established automakers.Speaking to AutoExpress, Dyson admitted the company does not have a prototype or even a chassis after two years of development. The inventor will not say what type of vehicle it is, though it will not be a sports car or a cheap car.

"There's no point in doing one that looks like everyone else's," he added. "We're not in that business ... We're trying to be radical."

The secret sauce could be found under the hood, as the vacuum cleaner maker already has extensive experience with batteries and electric motors. James Dyson is making a big gamble with solid-state batteries, a next-generation 'breakthrough' technology that has not yet matured into a viable competitor to traditional lithium-ion cells.

"We believe the batteries will be ready," he said. "We've done the chemistry but the manufacturing is highly complex."

The company is said to be pursuing two different solid-state technologies under development by separate engineering teams. It is unclear if either of the routes is similar to the solid-state batteries being pursued by Toyota or other players.

Dyson hopes to launch its first EV in 2020 as the inaugural model in a wider range.
