Herein, we report the first prototype of a highly bendable, quasi-solid-state Zn-poly(aniline-co-azure C) (PANAC) battery. The conformal assembly of the PANAC copolymer onto a porous carbon-sheathed carbon cloth was explored as a cathode, rendering the rich protonated nitrogen at a charged state and unique proton-self-supplier to drastically boost the polymer electroactivity in near-neutral aqueous electrolytes while enabling rapid electron/ion transport. This strategy harnesses the smart proton-self-regulation capability of a phenothiazine derivative in PANAC to surmount a long-standing conflict that the high electroactivity of the traditional polyaniline cathode demands a highly acidic environment, which is incompatible with Zn anodes. Thus, the aqueous Zn-PANAC cell delivers an impressive capacity and energy density of 306.3 mA h g(-1) and 352.3 W h kg(-1), respectively, - the highest values among the current zinc-polymer cells. The quasi-solid-state cell also yields a high capacity and energy density of 241.4 mA h g(-1) and 289.3 W h kg(-1), respectively, with a long lifespan (over 1000 cycles), and functions well when being bent, twisted, punctured and sewn.
