Battery performance also degrades on time and in rare cases your car can go up flames. A tank stays a tank, you only replace the fuel. If the fuel is compressed hydrogen you're essentially transporting a bomb in the car. Hydrogen also burns with an invisible flame which makes matters worse. If this stuff really exists and is not flamable, then it has some advantages over both batteries and compressed hydrogen.

Yes, but don't underestimate battery development. Semisolid and solid state batteries may become practical options for EVs. 24M, for example, claim a semisolid battery design that's 40% cheaper to produce with better energy density, better safety, and a longer duty cycle than conventional batteries: http://24-m.com/ http://24-m.com/ https://insideevs.com/24m-raises-22-million-semi-solid-state-battery/ https://insideevs.com/24m-raises-22-million-semi-solid-state... We'll have to see how they go, but if it does work as claimed then it'll be a significant step forward for EVs.

  It's mostly claims and organizations raising money for battery reasearch. I've seen lots of such claims for liquid electrolyte zinc or aliminium based flow batteries, but so far little seems to have materialized. Also battery performance degrades drastically at low temperature, so battery powered EVs are not such a great option in chillier areas. So far we are still running on battery tech first developed in the '70s with the first battery developed in the early '90s.
