Dyson, a company famous for its vacuum cleaners, fans and hand dryers, is aiming to become a big player in the electric car industry. The firm's founder has announced that it is investing ?2 billion in a push into automotive and battery development. Of that sum ?1 billion would be spent developing the car and the other ?1 billion in the solid state, not lithium, batteries to power it. Dyson aims to have its car ready for the mass market by 2020.
There is already a crowded field with established big automakers jockeying for position in the growing electric auto category. Toyota, Tesla, Nissan, Volkswagen AG, and even Jaguar all have big plans for battery powered automobiles. All of these firms are using lithium-ion batteries, however Toyota has previously stated that it intends to have solid state battery vehicles on the road by 2020.
