How plausible is this? Any EV/battery experts here? Could this battery tech be used elsewhere too? For example, in mobile phones.

Toyota has been talking about its amazing solid state battery tech since at least 2017 and back then they thought they would have them in 2022. And now the commercialization of these batteries is still as far away as they were back then. And Toyota also talk about them first being used in PHEV suggesting that they expect pretty low volume at first. Even if (and that a very big if) Toyota can have some products, with this in 2027 it will take years and years to get to a serious volume that matters in the EV market. The problem is Toyota is not credible, they have been talking for decades but have never had any independent verification of anything. If they were a startup they would be laughed out of the room. Car batteries and EV batteries are quite different and have different specifications. However in general yes, if Toyota really had figured out solid state technology, it might also improve phones. But they are different, it would be a lot of work both for the battery and to build a manufacturing plant for smaller batteries. In general if you have something that can break into the gigantic BEV market you don't bother with phones, its just distraction, scaling 1 cell to maximum volume is the major focus. There are already other innovations that help improve battery tech in phones, like silicon anodes (Sila for example) that is already going into consumer electronics. Both for consumer electronics and for cars its questionable if Solid state will ever be the correct answer and if so then when it will be dominate.

  They finally have a CEO who is happy to go in an EV direction instead of trying to do hydrogen. I suspect it will take a while to get things rolling again, but at least they aren't stalling anymore. They were first movers in this space with the Prius and it's been sad watching them squander that lead.
