AB - We report a neutral salt water based battery which uses p-type and n-typesolution processed polymer films as the cathode and the anode of the cell. Thespecific capacity of the electrodes (approximately 30 mAh cm-3) is achieved viaformation of bipolarons in both the p-type and n-type polymers. By engineeringethylene glycol and zwitterion based side chains attached to the polymerbackbone we facilitate rapid ion transport through the non-porous polymerfilms. This, combined with efficient transport of electronic charge via theconjugated polymer backbones, allowed the films to maintain constant capacityat high charge and discharge rates (>1000 C-rate). The electrodes also showgood stability during electrochemical cycling (less than 30% decrease incapacity over >1000 cycles) and an output voltage up to 1.4 V. The performanceof these semiconducting polymers with polar side-chains demonstrates thepotential of this material class for fast-charging, water based electrochemicalenergy storage devices.
