Panasonic Holdings Corp. will invest several billion dollars in a factory in Kansas to supply a new high-capacity battery for Tesla's electric vehicles, Nikkei reported Wednesday.

The Japanese conglomerate aims to triple or quadruple EV battery production capacity by fiscal 2028 from the current level of roughly 50 gigawatt-hours per year, according to the report.

Earlier in June, Reuters reported Panasonic was looking at potential factory sites in Kansas and Oklahoma to supply batteries to the U.S. electric automaker's plant in Texas.

Panasonic already has a factory in Nevada that supplies smaller batteries to Tesla.

Panasonic and Tesla did not immediately respond to Reuters' requests for comment. Kansas and Oklahoma government officials were not immediately available for comment.

The company, which is Tesla's battery supplier for more than a decade, also said it had shipped samples of its more powerful 4680 format battery to the electric-car maker.

The new battery is about five times bigger than those that Panasonic currently supplies, meaning the U.S. electric automaker could be able to lower production costs and boost vehicles' driving range.
