Toyota has what it considers a breakthrough in solid-state battery technology, and it won't share that development with Mazda and Denso, Automotive News Europe reports, citing an interview with Toyota's head of safety tech.
The three companies have teamed up for the very-Japanese-sounding EV Common Architecture Spirit. This partnership sees all three members working together tofor future EVs that will be shared across both automakers' lineups. The architecture is allegedly capable of handling both common lithium ion batteries, as well as Toyota's new solid-state tech, so keeping that tech in-house shouldn't affect the overall partnership.
According to earlier reports, Toyota's first solid-state-battery EV. While that would put Toyota behind the curve in terms of EV rollouts, the technology could provide Toyota with enough benefits that could put it ahead of its competitors.
Instead of using a liquid electrolyte, as current lithium ion batteries do, Toyota's solid-state batteries use a solid electrolyte. This can improve energy density, reduce the chance of overheating and, most importantly, drop quick-charge times down to a matter of minutes. Right now, the tech is too expensive to shove into any current car, but Toyota hopes it will be affordable at the beginning of the next decade.
Mazda and Toyota's partnership will come to the US by way of a $1.6 billion joint-venture plant. While the location is still unknown, this new factory could create up to 4,000 jobs and should be up and running as soon as 2021. The factory won't build this new EV, but rather existing models -- thefor Toyota, and a new crossover model for Mazda.
The two automakers have also teamed up to develop the latest generation of. First appearing on the , the system will initially surface in a Mazda when the new Mazda3 debuts in the near future. It's capable of over-the-air updates thanks to a new Wi-Fi hotspot with a built-in cellular antenna.
