Empowering the smart grid: can redox batteries be matched to renewable energy systems for energy storage?
This paper develops the first mathematical model of the promising cerium-zinc redox battery using an undivided cell. These have no costly separating membranes, which contribute a significant power loss and introduce junction potentials. Using various charging waveforms to mimic different renewable energy output profiles, we demonstrate redox batteries to be suitable storage media for most renewable energy technologies and show this depends on the anticipated discharge load. We also show how the model will be useful in optimisation of redox battery design by identifying general cell characteristics to deliver high energy/power.
