Toyota is fast-tracking its long-promised all-solid-state EV batteries through a [1]new partnership with Sumitomo Metal Mining, aiming to debut its [2]first production vehicle using the technology by 2027 or 2028 . Electrek reports:
> Toyota said that its new batteries could significantly enhance driving range, charging times, and output, potentially transforming the future of automobiles. Compared to current liquid-based batteries, which use electrolyte solutions, Toyota's all-solid-state batteries utilize a cathode, an anode, and a solid electrolyte. According to Toyota, the next-gen battery tech "offers the potential for smaller size, higher output, and longer life."
>
> The two companies have been developing cathode materials for all-solid-state EV batteries since 2021, focusing on some of the biggest challenges in producing them at a mass scale. Using Sumitomo Metal Mining's proprietary powder synthesis technology, Toyota claimed to have developed a "highly durable cathode material" for all-solid-state batteries. Sumitomo has been supplying cathode materials for electric vehicles for years, but it's now working to introduce the newly developed tech, moving it toward mass production.

1995 is over, Toyota.
Sumitomo, really? (Score:2)

15 years ago Sumitomo was promising low temp molten salt batteries at 1/10th the cost of Li-on by 2015.
I followed this for some years but iirc the company stopped talking about it entirely by about 2017

Wow, they use a cathode and an anode? HIGH TECH SHIT.
Seriously though, I am hoping they are successful. I want batteries to continue falling rapidly in price so I root for any improvements anywhere. Competition is good. I also still want to see NCM banned for multiple reasons, and having more alternate and safer options makes that more likely.
VW? (Score:2)
Didn't Toyota have a joint venture with VW on this tech? I see some vague mention of solid state batteries in VWAG's future product lineup:
