It'll happen industry-wide. But don't hold your breath just yet.

Also, its interesting to see that Rivian is going forward with solid-state batteries so far, meanwhile Fisker is pulling out.

I'm curious to see what Rivian is able to come up with for solid state and when they're able to pull it off because Toyota is expected to reveal a solid state battery this year and is expected to hit production in 2025.

The batteries will offer more range in the same size pack, but the automaker still has to solve the technology’s life-span problem.

It still seems like it is much further away than 2025 for any real mass production of this technology. The article from Dec 2020 does not talk about the challenges but the one from July 2020 talks about some of the major hurdles still needed to over come, the least of them being the manufacturing process that is currently not scalable. Also with safety and durability issues (multiple charging causing pack failure) the article states do not expect it in a vehicle soon and are targeting limited production by 2025. Seems like best guess is it may start hitting the real world by the end of this decade but any expectation sooner than that seems unrealistic. I just do not see how they can get any real long term testing completed before that (only my opinion).

Yup. Quantumscape can power your phone with their "breakthrough" technology but manufacturing a sufficiently large EV battery in sufficient volume is years away. Everyone (maybe not Fisker) is trying to find the key to solid state battery technology, but we're not a heckuva lot closer than we were a year ago.

Toyota's involvement has me wondering if there will be some overlap throughout the process. I doubt Rivian will be doing 100% of it in house but probably more so engineering, assembly, etc.

Do you mean with Toyota or with someone else? I don't think Toyota will want to share this with anyone.

So...could it be that Rivian is working on Solid-State Battery for a portable power bank to extend range as needed?

Seems much more plausible at this stage to me.

It wouldn't be completely unheard of since Rivian has patented a detachable backup battery pack.

Rivian Files Patent for Detachable Backup Battery Pack

Rivian has filed a patent with the USPTO for a backup battery pack that can be detached and charged separately from the main pack. I've attached the full PDF below.

Seems solid state batteries may double the energy density. That helps, but still isn't enough to make them feasible for portable battery modules, imo.

A 50 lbs solid state battery (not counting enclosure) would only provide about 25 miles range.

Tests show why QuantumScape solid-state battery has serious backing

California's QuantumScape has announced stunning performance figures for what may be the first commercially viable solid-state lithium-metal battery. It's claimed to add as much as 80 percent to the range of an electric car, and charge from 0-80 percent in just 15 minutes.

Yes. What would be interesting is how they can do it differently from the many other brands expected to create EV power banks of their own. Here's one example in the works.

Let's not get ahead of ourselves here. They're setting up a team. Getting from there to production is no small feat considering that others have been trying for years and aren't especially close.
