(I know nothing about batteries or chemistry) I think this research only focuses on power generation, the device where you combine the liquids to get energy. Changing the energy density means changing the type of liquid, I assume, which this research is just not about. I understand it as analogous to a ICE, where you have the fuel and the motor. But with flow batteries you can also go in reverse to create fuel from energy. The research featured here is about the motor but if you need a different energy density you have to change the type of fuel since that's how the energy is just stored in huge tanks.
