Smaller, cheaper flow batteries throw out decades-old designs
> showed that the battery had a charge densities of about 1,322 watts per liter of electrolyte and a discharge density of about 306 W/LIsn't the relevant measurement energy density (Wh/L) rather than power (W/L)? I guess there's some limit on the power generated by a given volume of the battery, but in practice it seems like the main question is how big the tank has to be per MWH/KWH, rather than how big the power module has to be to convert that back to energy over the duration of the discharge period.
