Describes the mechanism causing the electrolyte cracking and resulting short-circuits (dendrites form at the electrodes and penetrate the solid electrolyte).

Does not describe a way to prevent it, so solid-state batteries don't seem like a realistic product for now.

Every lithium battery in use today is susceptible to dendrites. One of the promises of solid state batteries is more safety, not less.

Agree, but as of now it's seems like it's still a promise, not a reality.

till now I was under the impression, that that was the advantage of solid electrolytes: preventing the dendrites in the first place (being a natural barrier to build dendrites).

guess I was wrong
