Toyota stated it’s heading in the right direction to introduce solid-state batteries to its automobiles by “2027-2028” with a shelf-life of as much as 40 years – 4 instances the present lifespan for many electrical automobile (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 spread of greater than 1000km on a single cost from a battery pack that’s smaller, lighter and cheaper to fabricate than current 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 real looking 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 automobile, unlocking potential for battery swaps between automobiles and making increased preliminary prices value it in the long term.
Chatting with 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 we have now 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 we have now the method of that, then how we must always … scale back the fee.”
“That could be a crucial level to broaden the solid-state battery know-how.”
This implies the tech can be first provided in Lexus or Century fashions, taking longer to filter right down to mainstream automobiles such because the next-generation Toyota Corolla previewed by a hanging idea automotive in Tokyo.
But Kaita-san stated Toyota’s SSBs can be able to lasting longer than the automotive, with a staggering claimed lifespan 4 instances larger than present battery packs, delivering homeowners higher worth.
“So initially, certainly, the worth is way increased – 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 automobile is perhaps scrapped – we are able to take away the battery to a brand new automobile, two instances, perhaps 3 times [over its lifespan].
“In comparison with the prevailing lithium battery we’re making now, by the everyday 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 response to the engineer, given 4 current batteries must be manufactured for each SSB.
In October 2025, Toyota signed a collaboration with Sumitomo Metallic Mining for the mass manufacturing of cathode supplies for SSBs, that are known as ‘strong state’ as they’ve a strong (versus fluid) electrolyte.
Whereas not confirming automobiles SSBs can be provided in, Toyota stated it’s on observe to ship them to showroom fashions in “2027-2028”.
The bZ4X SUV is the one Toyota EV at the moment in Australian showrooms, with the bZ4X Touring, carefully associated to the Subaru Trailseeker, confirmed for an area launch in 2026.
