Reports this week from major media outlets say Toyota has made a breakthrough on solid state batteries that could revolutionise the future of electric vehicles. But the claims should be taken with a grain of salt: Toyota has a history of unfulfilled big promises on batteries going back over a decade.
“Toyota claims battery breakthrough in potential boost for electric cars” read one headline in The Guardian this week. The article claims Toyota believes it could make a solid-state battery with a range of 745 miles (1198km) that charges in 10 minutes.
The article states that Toyota is pursuing a plan to roll out electric vehicles with the new solid state batteries by 2025.
That would be great, were it to happen. But the reality is that Toyota produced just 8000 electric vehicles in the first half of 2023, making up just 0.19% of the company’s total production.
And Toyota has a history of talking big on battery and hydrogen breakthroughs but never seeming to follow through with actual production.
Toyota’s track record of battery spin was picked up today by climate and energy researcher Ketan Joshi, who posted screenshots of Toyota’s unfulfilled battery claims going back to 2009.
One headline from Forbes in 2017 reads “Ultrafast-Charging Solid-State EV Batteries Around The Corner, Toyota Confirms”.
Another headline from 14 years ago reads “Toyota Develops More Efficient Battery, Tenfold Improvement In Capacity May Be Possible”
“If Nikkei’s estimate is on the money, a ten-fold increase in range means Toyota’s next-generation hybrids and EVs could easily travel between Melbourne and Sydney on a single charge.” says the 2009 Drive article, which said at the time that such batteries were not expected to arrive until sometime after 2015. We are still waiting.
In its story on Toyota’s latest battery claims The Guardian states: “Toyota says it has made a technological breakthrough that will allow it to halve the weight, size and cost of batteries, in what could herald a major advance for electric vehicles,”...
However Kaita’s claims that current batteries are too expensive also doesn’t fit with reality as Tesla is already producing vehicles with up to 600 km range with some of the highest profit margins ever seen in the automotive industry.
