I'd like to see one of these paired with my solar: New type of battery could outlast EVs and still be used for grid energy storage

I like technology and am usually impressed on the advances that it brings. I'm floored on the strides of battery technology. Ask me 20 years ago and I would think none of this would have happened.

That said, if any of that is true [I doubt everything], the battery will last over 50 years [80% rating] if it was cycled every single day. I think many of us had our first RV around 30yo. Once you buy that battery, it would probably last longer than you. The other thing is, even at 80%, it still would be good enough for me.

For me, any battery that lasts that long is like me being hungry and going to a buffet. There is only so much I can eat and the rest would be wasted.

Just think, in a few more years, they will have battery that will last over 80 years.

Cynic hat on….What modern day manufacturer would ever want to sell an item with this kind of longevity that may even outlast their business.

Manufacturers and retailers want things to fail after certain time frame so we go buy another. The throwaway model.

Well, they sell 50 and 100 year roofs, right ?

If the longevity pans out and it has the energy density hinted at in the article the market (EVs, RVs, homes, businesses, utility energy storage, etc) will be absolutely huge. I'd be happy to supply the world for 20 years and retire a trillionaire. lol

Energy storage is about the only market I can see a use for that longevity.

There is no market for that type of battery for automobiles/RV's. You can't get most of those vehicles to 10 years without a major break down.

Heck, people can't seem to stay married for more than 8 years. Are you saying they can still be in love with their batteries that long?

Anyway, impressive data but to date, I have only cycled my batteries [after two years] no more than 4 times.

I'm saying that batteries that can last that long would/will have great value to society - in many ways. That worth may start in an EV, or may not. Whatever.

Great article @Soundsailor

While this article seems to focus more on battery longevity, there are a couple of other characteristics that may be more important to the RV world. From what I have read, the single-crystal electrodes allow for significantly higher charge/discharge rates. This technology is also expected to allow for significantly higher energy density - much more stored power in the same footprint. I think the next couple of years will see some significant advancements.
