> It seems like I see headlines every few months that a lab somewhere has created

Mostly because it is very much needed for a whole lot of things from mobile phones to cars to making solar energy work 24-7, so if someone gets there first they will become immensely wealthy capitalising on a shift of our civilisation.

But yeah, proof of concept is not path to market, press releases are not profits and all that.

I am also sceptical of claims that a new battery is both safer and energy-denser. These two things are not natural allies.




The press release says that it has an energy-density comparable to that of lithium-ion batteries, which in PR speak means "a little bit less than the worst lithium-ion batteries" which means "less energy-dense".


Right. If it actually were better than lithium ion, they wouldn't be shy about saying so.
