Yes, but this is changing and there are a number of very interesting options.

Very cool, there are definitely use cases where batteries are necessary (like moving vehicles) and it’s great to see advancement in battery tech.

EDIT: These batteries seem to be even less energy dense than Li-ion which is one of the weaknesses of batteries in comparison to hydrogen.

Yes, that is their shortcoming for now, but for solar storage and such they are an interesting option.
