Does fast charging reduce the lifespan of a battery like this? The headline is bothersome because my suspicion is it won't last 20 years if you fast charge all of the time and whatnot. I realize that's not a typical case but it's good to understand the trade-offs.

The chemistry is substantially different, so we'll probably have to wait until scientists run some tests to get a more precise set of parameters that affect degradation. I expect failure modes like dendrites are basically impossible with solid-state, but electrode cracking is still possible. There might even be new and exciting ways they can degrade! Regardless, this is still great news.
