If I had a dollar for everytime they think they've made better batteries....

Hope it's true but as someone who likes drone racing which is currently limited by battery tech I've heard this a bunch over the last 6-7 years

Battery density improves around 5-8% per year, so the gains are small but steady. None of these 50% gains that always get talked about ever come to anything, but over time it all adds up.

They often do, it just takes a decade, so it looks like another 5-8% improvement when it hits market.

No, they are just small iterations actually. No one cell make that much of a big jump in one go. I follow battery news and youtube channels on the subject every single day.

LiFePO4 was a huge jump in cycle count, charge rate and cobalt usage but charge rate wasn't even state of the art once commercial. Lithium was a huge jump in density. Hard carbon anodes were a huge jump when first investigated, but small hop once commercialised. Various low nickel and low cobalt cathode improvements were 20-40% better than status quo when discovered. Some Zinc based chemistries are a huge jump from what was normal when discovered, but are niche now.

The techniques and knowledge also apply to other things.

Same with cancer, a new cure is always on the way

It never materialises

Yet the mortality rate goes gradually down
