Toyota stated it’s heading in the right direction to introduce solid-state batteries to its autos by “2027-2028” with a shelf-life of as much as 40 years – 4 occasions the present lifespan for many electrical car (EV) batteries.
Stable-state battery (SSB) know-how has been touted as a ‘silver bullet’ for EVs by a number of producers together with Toyota, Honda and Mercedes-Benz.
It guarantees a variety of greater than 1000km on a single cost from a battery pack that’s smaller, lighter and cheaper to fabricate than present batteries.
For context, the longest electrical vary determine claimed by an automaker in Australia is 750km, for the 2026 Tesla Mannequin 3 Lengthy Vary Rear-Wheel Drive. That’s on the extra life like WLTP cycle.

A nickel manganese cobalt (NMC) battery is used on this Mannequin 3, in addition to within the flagship Efficiency variant.
But Toyota says its new solid-state tech will go additional with a lifespan past the remainder of the car, unlocking potential for battery swaps between automobiles and making greater preliminary prices price it in the long term.
Talking to Australian retailers together with CarExpert on the Japan Mobility Present (JMS) in Tokyo, Keiji Kaita – president of Toyota’s Carbon Impartial Superior Engineering Improvement Centre – stated SSBs received’t be low cost to start with.
“This is without doubt one of the factors now we have now clarifying with our provider,” Kaita-san stated.
“[We have] Assumed price versus amount price … and we additionally assume the demand versus value price – after which now we have the method of that, then how we should always … scale back the fee.”
“That could be a crucial level to develop the solid-state battery know-how.”
This implies the tech might be first supplied in Lexus or Century fashions, taking longer to filter all the way down to mainstream autos such because the next-generation Toyota Corolla previewed by a hanging idea automobile in Tokyo.
But Kaita-san stated Toyota’s SSBs might be able to lasting longer than the automobile, with a staggering claimed lifespan 4 occasions better than present battery packs, delivering house owners higher worth.
“So initially, certainly, the value is far greater – however step by step that may get near others – however we’d like to make use of the long-life, tremendous long-life [lifespan] options,” he stated.
“Even when the car is perhaps scrapped – we will take away the battery to a brand new car, two occasions, perhaps 3 times [over its lifespan].
“In comparison with the present lithium battery we’re making now, by the standard utilization, our goal is perhaps 10 years, 90 per cent capability,” the engineer stated.
“This [SSB] is perhaps 40 years, 90 per cent capability – that is the potential we’re focusing on.”
This additionally means the carbon footprint from manufacturing is just 25 per cent, in keeping with the engineer, given 4 present batteries must be manufactured for each SSB.
In October 2025, Toyota signed a collaboration with Sumitomo Steel Mining for the mass manufacturing of cathode supplies for SSBs, that are known as ‘stable state’ as they’ve a stable (versus fluid) electrolyte.
Whereas not confirming autos SSBs might be supplied in, Toyota stated it’s on monitor to ship them to showroom fashions in “2027-2028”.
The bZ4X SUV is the one Toyota EV presently in Australian showrooms, with the bZ4X Touring, carefully associated to the Subaru Trailseeker, confirmed for an area launch in 2026.
