Toyota might just be about to change the world of EV battery tech forever.
And that is because the Japanese brand is aiming to launch the ‘holy grail’ of battery tech.
Said tech involves the development of solid-state batteries.
And this EV battery tech could be here as soon as 2027.

Toyota could be about to change the EV world
Toyota is a brand that is constantly looking to innovate and develop.
The Japanese marque is, officially, the world’s largest car manufacturer.
And, like any manufacturer, it is always looking for ways to get ahead of the competition.
For one thing, the brand is reportedly planning to develop new EVs in Europe.
It is also being suggested that the brand is planning two new EV SUVs based on the Land Cruiser and the RAV4.
Those particular projects are being lined up to be built in Kentucky.
But now, the marque is working on something else entirely – and it could change EV battery tech forever.
Japan’s flagship brand recently announced a partnership with Sumitomo Metal Mining Co.
This partnership aims to mass-produce cathode materials for brand-new battery tech.
Toyota has said that its aim is to ‘achieve the world’s first practical use of all-solid-state batteries’ in its EVs.
Okay, so what exactly does all of that mean?
The science behind the EV battery tech is fascinating
Well, it’s all to do with the science of EV battery tech, and it’s actually quite interesting.
Current lithium-ion batteries use liquid-based batteries; these utilize electrolyte solutions.
By contrast, Toyota plans to introduce a brand-new, solid-state EV battery that is different.
This battery is different because it would use solid electrolytes, a cathode, and an anode.
According to Toyota, this next-gen EV battery tech ‘offers the potential for smaller size, higher output, and longer life.’
Reports suggest that the brand is planning to bring this new EV battery tech to the market soon.
As a matter of fact, this potentially game-changing tech could be here as soon as 2027 or 2028.
Toyota and Sumitomo have reportedly been working on this tech since 2021.
That means that the Japanese marque is already very far down the line with development.
Could this technology completely change the EV world when it eventually arrives?
