a Schematic figure of the dual-ion doping mechanism of symmetric PANI electrodes during charge. b Failure mechanism of symmetric PANI electrodes in 2 m NaTFSI aqueous electrolyte. c Stable all-polymer ASIBs enabled by 2 m NaTFSI polymer-aqueous electrolyte. d Comparison with other all-organic ASIBs assembled with carbonyl derivatives anodes and PANI cathodes. e Specific capacity (SC), energy density (ED in blue), capacity retention (CR), cycle number (CN), metal-free (MF), and electrolyte dilution (ED in red) of this work in comparison with advanced ASIBs. Both specific capacity and energy density are calculated based on the mass of active materials in cathodes. MF, all organic electrodes: 1; single organic electrode: 0.5; all inorganic electrodes: 0.
