Abstract:

We report the first proof of concept for a nonaqueous, all-organic semisolid flow battery (SSFB) using suspensions of 10-methylphenothiazine@Ketjen black and thioxanthone@Ketjen black dispersed in tetraethylammonium hexafluorophosphate/acetonitrile as the cathode and anode, respectively. A proof of principle cell with an open circuit voltage of 2.35 V demonstrated an average coulombic efficiency of 83% within the voltage range 3.0-0 V. This study provides a potential path for developing new high energy density and cost-effective nonaqueous organic SSFBs.
