I feel like I've seen 10 or so cutting edge separators that allow for the use of metallic lithium without dendrite growth or dangerous rapid discharge. This would apparently lead to a massive increase in power density. Are they all being sat on by patent trolls or what? I'm all for making sure that inventors get paid, but at some point I feel like the US government should just be handing out 10 million dollar prizes to people who come up with humanity saving tech, and then making the tech fully patent unencumbered so anyone can build with it. Battery tech is too important for the survival of our species to get caught up in these silly hostage negotiations.
