Toyota Motor Corp.'s work on sodium ion batteries has produced technology that could double the driving range of an electric vehicle, The Nikkei reports.

The company has demonstrated the chemistry in a coin-sized battery that generates voltage at room temperature that are 30% greater than a lithium-ion battery of the same size. The design is likely to be cheaper too, according to Toyota.

The newspaper cites an unidentified executive who says the technology, if proven viable, could enable EVs to drive 310-620 miles per charge. Toyota says it hopes to commercialize the sodium chemistry by 2020.
