I didnt know it was the silver that was best for solid-state, but I know they are definitely safer i remember the early videos of people cutting into paper thin cells powering an led and it stayed lit, with mild flicker. Its may prove to be a huge leap for many aspects of tech and if as safe as they claim theoretically (we will see if they can still spark on the roads) then EVs would be potentially safer than gas in some cases and with a 20 year life span and potentially more in later generations it may just make EVs worth it over a Gas counterpart. If they become affordable as well that is.

Maybe im just hopeful haha. I just wanna see some good news for tech again. Its been so negative lately.
