Non-aqueous semi-solid flow battery based on Na-ion chemistry. P2-type Na(x)Ni(0.22)Co(0.11)Mn(0.66)O(2)-NaTi2(PO4)3

Chem Commun (Camb). 2015 Apr 30;51(34):7298-301. doi: 10.1039/c4cc09597a.


We report the first proof of concept for a non-aqueous semi-solid flow battery (SSFB) based on Na-ion chemistry using P2-type NaxNi0.22Co0.11Mn0.66O2 and NaTi2(PO4)3 as positive and negative electrodes, respectively. This concept opens the door for developing a new low-cost type of non-aqueous semi-solid flow batteries based on the rich chemistry of Na-ion intercalating compounds.
