For 10 KWh, there has to be an either 4 or 2 m² (70-140 f³; unsure about the calculation) big tank for pure oxygen! That would take one main advantage, the energy density. However, this may not be the main goal of this project (as saving solar energy isnt normally on space). The Advantages however are enormous, starting with a theoretical even higher lonevity than even the edison batteries (in theory, the only thing that can break over time here is the casing...), an even cheaper production (no iron required, no nickel, which costs the doubled amount of zinc, but only has a fraction of the density).
