Funnily enough, I remember reading an article many years ago (I was about 10, so it would have been mid to late 80s) about LiPo being the next big thing, and the author making all sorts of claims about how battery technology announcements being over-hyped. You're correct, but eventually one of these announcements will live up to the promise. LiPo was basically stumbling due to a few manufacturing at scale issues at the time, and once those got solved (Sony released a standard LiPo cell in 1991) it wasn't long before it became the new standard. I'm still sceptical of new battery tech announcements, but I still get excited by them!
