Cheap proton batteries compete with lithium on energy density (newatlas.com)

edit I am an idiot, who uploaded the image link as the URL. The original source should now be accessible

RMIT engineers say they've tripled the energy density of cheap, rechargeable, recyclable proton flow batteries, which can now challenge commercially available lithium-ion batteries for capacity with a specific energy density of 245 Wh/kg.

it also lasts a lot of cycles something like 6000-8000 so it will work for decades

Not good enough for the next 10 years.

Energy density and charging speed must, and will, improve by much more.

The good news is that funding is finally being given for it so advancement will happen

Most applications assume max 2 charge/discharge cycles per day, don't they?

And where space is not an issue, a cheaper option could be favourable? Im afraid I don't understand both your points

Of course you can't LOL, if cycles per day and cheap is all that you can think, because I simply haven't talked about these two topics.
