On July 3, the company said it had simplified the production of the material used to make solid-state batteries and hailed the discovery as a significant leap forward that could dramatically cut charging times and increase driving range. “For both our liquid and our solid-state batteries, we are aiming to drastically change the situation where current batteries are too big, heavy and expensive. In terms of potential, we will aim to halve all of these factors.”said Keiji Kaita, president of the Toyota research and development center for carbon neutrality.

He added that his company has developed ways to make batteries more durable, and believed it could now make a solid-state battery with a range of 1,200 km (745 miles) that could charge in 10 minutes or less and would be simpler to manufacture than a conventional lithium-ion battery.
