Toyota is hoping to launch electric cars using its revolutionary all-solid-state EV battery as soon as 2027.
Dubbed the ‘holy grail’ of EV tech, solid-state batteries could be an absolute game changer for the future of electric vehicles.
The batteries could offer some huge advantages over the lithium-ion batteries, which are currently used in EVs.
And they could be here sooner than you think, with reports suggesting Toyota could launch its first all-solid-state battery-powered EV as soon as 2027.

All-solid-state batteries have been dubbed the ‘holy grail’ of EV tech
When it comes to switching from a gas-powered car to an all-electric one barrier for some folks is the fear of range anxiety, and having to wait around while the EV charges.
However, the all-solid-state EV battery could be the answer.
These game-changing batteries are known as the ‘holy grail’ of EV technology, and it’s not hard to see why, as they offer better range, a longer lifespan, and much speedier charging times.
An all-solid-state EV battery uses solid electrolytes instead of the liquid ones that you find in lithium-ion batteries.
This means that they allow for a much faster movement of ions, while also being able to handle high temperatures and voltages better than their lithium-ion counterparts.
Toyota has been working on all-solid-state EV batteries for a while now, but this week the carmaker announced it had formed a partnership with Sumitomo Metal Mining Co to ‘mass produce cathode materials’ for the new batteries.
“They aim to achieve the world’s first practical use of all-solid-state batteries in BEVs, potentially changing the future of automobiles and helping realize a carbon-neutral society,” the two companies said in a statement.
Toyota went on to say it is ‘aiming for a market launch of BEVs with all-solid-state batteries in 2027-28’.
Toyota isn’t the only carmaker working on the new tech
While Toyota has now boldly announced it plans to ‘achieve the world’s first practical use of all-solid-state batteries’ in EVs, it’s not the only carmaker working on the new tech.
Back in February, Mercedes-Benz announced that it had put ‘the first car powered by a lithium-metal solid-state battery on the road’.
The prototype was made using a modified EQS, equipped with new batteries and other parts.
Alongside that, Nissan, Honda, Volkswagen, BMW, Ford, and Tesla are all also reportedly working on all-solid-state batteries, but who will cross the finish line first?
