Toyota claims a leap that would vastly increase electric-car range

In an unusual statement, Toyota says it is nearing a breakthrough in a type of lithium-ion battery system that has vexed researchers for decades, and that it will unveil a family of electric cars with a jump in currently available range in the early 2020s.

Why it matters: Given the high stakes and risk of embarrassment if something goes wrong, Japanese companies virtually never flag a big tech breakthrough before it is actually produced and delivered to the market. Hence, Toyota's comparatively specific announcement suggests it is reasonably confident that it really has mastered a new battery technology, said Venkat Viswanathan, a professor at Carnegie Mellon University.
