That breakthrough comes few times every year past four, five years…

It took about 100 years from car designers knowing electric motors were superior to internal combustion engines for batteries to more-or-less be good enough and more-or-less inexpensive enough for mass production of EVs.
I wouldn't hold my breath for breakthrough in a short time period, though at least now lots more R&D is being done.

The probability that we will see a car with a battery in it matching Toyota’s claims by 2027 is somewhere between zero and .0000001.

Toyota claims battery breakthrough in potential boost for electric cars

Japanese firm believes it could make a solid-state battery with a range of 745 miles that charges in 10 minutes


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.
The world’s second largest carmaker was already pursuing a plan to roll out cars with advanced solid-state batteries, which offer benefits compared with liquid-based batteries, by 2025.


On Tuesday, the Japanese company said it had simplified production of the material used to make them, hailing the discovery as a significant leap forward that could dramatically cut charging times and increase driving range.


“For both our liquid and our solid-state batteries, we are aiming to drastically change the situation where current batteries are too big, heavy and expensive,” said Keiji Kaita, president of the Japanese auto firm’s research and development centre for carbon neutrality. “In terms of potential, we will aim to halve all of these factors.”


David Bailey, a professor of business economics at the University of Birmingham, said that if Toyota’s claims were founded, it could be a landmark moment for the future of electric cars.


“Often there are breakthroughs at the prototype stage but then scaling it up is difficult,” he said. “If it is a genuine breakthrough it could be a gamechanger, very much the holy grail of battery vehicles.”


Kaita said the company had developed ways to make batteries more durable and believed it could now make a solid-state battery with a range of 1,200km (745 miles) that could charge in 10 minutes or less.


The company expects to be able to manufacture solid-state batteries for use in electric vehicles as soon as 2027, according to the Financial Times, which first reported on Toyota’s claimed breakthrough.


Solid-state batteries have been widely seen as a potential gamechanger for electric vehicles, promising to reduce charging times, increase capacity and reduce the fire risk associated with lithium-ion batteries, which use a liquid electrolyte.


However, solid-state batteries have typically been harder and costlier to make, limiting their commercial application.


Toyota said it believed it could simplify the production process, potentially making solid-state batteries easier to produce than lithium-ion ones.


The Japanese carmaker has been seen as something of a laggard compared with rivals in the electric vehicle market. In June last year it recalled 2,700 of its first electric vehicles because of concerns the wheels could fall off.


Last month, the Advertising Standards Authority banned adverts by Toyota and Hyundai for exaggerating the speed at which electric cars could be charged and misleading consumers about the availability of rapid charging points across the UK and Ireland.

Good to hear that Toyota is (perhaps) getting serious about EVs. Their next move should be the really really cute new Prius, but full EV, with say a 60KWH solid state batter and a $35K price point.

It's interesting Toyota making these claims when you look at their performance in this area (FT article from this week).
Although I don't know if battery tech is specifically covered by 'digital innovation'.

Toyota have been backward about EVs.
OTOH the hybrid cars must have very good charging software for good battery life, both for the straight hybrid and the plug ins.
I bought a Prius in 2005 because I was interested by the clever hybrid design and E-CTV. My daughter has it now and it is still in daily use on it's original hybrid battery (Nickel metal hydride though iirc)

Next we bought an early plug in Prius in 2012. This has lost about 10% of its plug-in range in 12 years and is used by my wife. She is not very disciplinned about not charging until needed though and has spent a lot of its life fully charged.

I currently also run a 2018 plug in Prius, which my Taycan was supposed to replace but doesn't, so I haven't sold it, which has lost no plug in range at all yet, still the same after 6 years and about 6 miles/kWh, used daily.

Very interesting article on the impact of a silicon anode on charging speed. The car isn’t production, but simply to prove a point.

I know the title of this thread is about Toyota innovation, but as this recent article from Top Gear shows, innovation in battery technology is actually quite widespread.

For all I know Toyota‘s being left in the dust in this area, but it’s great to see that other companies have picked up the mantle of solid-state anode batteries. From what I’ve read this is a game changing technology for battery range, charging speed, and battery life.
