A simple way to significantly increase lifetimes of fuel cells and other devices

The paper mentioned in the article: https://pubs.rsc.org/en/content/articlelanding/2022/ee/d1ee0...

They mention lithium, but not if it’s lifetime it’s also extended, is it?

If it is, isn’t that a huge deal?

This was probably known for a while but hidden as a fact so that devices would die prematurely and users would need to buy newer ones sooner.
