I set out to write about #solid-state #battery technology, and descended into the rabbit hole of EV-sized energy storage. Lithium-sulfur! #GM's #Ulitum with less cobalt! Batteries with silicon where the graphite used to be!

It's a veritable battery bonanza. And both the #IRA and #IIJA are shaping the industry in ways no one really understands yet.

Thanks to editor Elizabeth Royte for helping me make sense of it all.
