You... You think a battery is a magic physics defying substance?

I mean, I don't see capitalism beeing a way to solve the climate crisis and do belive that degrowth is going to happen (by design or desaster), but the success of renewable energy is very much a capitalism success story.

Clearly they only think bigger, better batteries are magic and physics defying. The batteries we have now are the best batteries that physics allows for, and they can't be made more or bigger because... We already used up all the stuff for them. Yeah, that tracks.

The classic capitalist solution "make it bigger, make more of it, there are absolutely zero limits."

Quick question, how big would a battery have to be to power a single city of >1000000 for a single day, show your work.

"Battery" does not mean "chemical battery". Gravity batteries, for example, already do provide power to midsized population centers around the world-- they're called hydroelectric dams.

On top of that, it doesn't have to power the city for a day, it only has to store unused energy produced during off-peak hours while the sun is shining and/or wind is blowing.

Right-- batteries don't power cities, they just smooth out the power generation. The size of the battery is determined by the reliability of power generation, desired uptime, etc., not just by the power consumption of the city.

Sorry, but you are wrong, battery means exactly chemical battery

Gravity electrical storage is not a battery

You linked the Wikipedia page on electric batteries. Of course it's going to talk about the things you put in your remote, because Wikipedia is not a dictionary and that's what most people mean when they say "battery". See also, the pages on energy storage that refer to them as batteries:

You could also look at the Wikipedia disambiguation page for "battery", found at /wiki/Battery, which mentions electrochemical batteries as the most common meaning and then has an entire section on energy storage that mentions "Energy storage, including batteries that are not electrochemical".

You are wrong.
