Tesla Motors, Panasonic, and other Japanese companies are planning to invest close to $1 billion in a US battery plant, according to Nikkei.
With a target date of 2017, the lithium-ion-battery facility will "handle everything from processing raw materials to assembly," Japan's largest business daily said on Wednesday.
Panasonic, which is an investor in Tesla, is inviting a number of Japanese materials makers to join the project, with a total investment estimated to reach more than 100 billion yen ($965 million), Nikkei said.
This is a non-trivial investment for an electric car maker as the battery represents a large part of the vehicle's cost, Nikkei pointed out.
One of the aims of the plant is to bring down the cost of the battery component and make future Tesla models more affordable. The Model S starts at about $70,000.
The plant may also supply Toyota and other automakers with batteries. There are also plans for "home-use" storage batteries in order to boost product numbers, Nikkei said.
