    However, this technology does not yet match the energy density of lithium-ion batteries.

    It would be good if you actually told us what that energy density is…

      Two important parts of a battery are how much energy it can store in a certain space and how much it weighs. If it is bigger and holds the same amount of energy that might be ok for a non mobile storage if it costs less, like a house. If it weighs more for a certain energy that wouldn’t be useful for cars and mobile things but might be ok for small things where the weight is negligible anyway. For cars you want a small energy dense battery that is light as possible
