They are bulky and last ten years in an extreme temperature range. I wonder if these could replace lead-acid batteries in ICE cars, which usually last 3-5 years.
I am by no means an expert, but I seem to remember that the reason lead-acid batteries are good for that particular job is that they can release a huge amount of stored energy in a very short time, which is what you want when you need to fire the ignition of a car. I think other battery types are much more limited in their maximum power output. I am absolutely not sure this is also true for this new type of battery, but it might be.

The only downside seems to be price. It’s about $388 USD whereas my last battery was about $150.
But that’s cool that they exist.
