Toyota will soon increase its production of higher-energy-density batteries sixfold with an eye to putting them into the Prius at an unspecified point in the future.
The plan is for Toyota and production partner Panasonic to build a new production line that will be able to make 200,000 li-ion batteries a year.
The companies will spend about 20 billion yen (AU $197 million) on the project.
