| description | A symmetric solid-state battery based on organic porous electrodes is fabricated using scalable spray-printing. The active electrode material is based on a textile dye (disperse blue 134 anthraquinone) and is capable of forming divalent cations and anions in oxidation and reduction processes. The resulting molecule can be used in both negative and positive electrode reactions. After spray printing an inter-connected pore honeycomb electrode, a solid-state electrolyte (σLi: × 10−4 S cm−1) based on a polymeric ionic liquid is spray-printed as a second layer and infiltrated through the porous electrodes. A symmetric all-organic battery is then formed with the addition of another identical set of electrode and electrolyte layers. Both density functional theory calculations and charge-discharge profiles show that the potentials for the negative and positive electrode reactions are amongst the lowest (≈2.0 V vs Li) and the highest (≈3.5 V vs Li), respectively, for quinone-type molecules. Over the C-rate range 0.2 to 5 C, the battery has a discharge cell voltage of more than 1 V even up to 250 charge-discharge cycles and capacities are in the range 50–80 mA h g−1 at 0.5 C. |
