Due orientation polarization with force electric field, PPS π–π conjugated pyridinio cations strong coordination ability sulfonate anion tends generate dynamic adsorption layer build unique water–poor interface. steric hindrance effect can attract solvated 2+ , thereby promoting desolvation process. Moreover, by providing large number nucleation sites inducing ion flow, preferred (002) crystal plane be achieved. Therefore, interfacial electrochemical reduction kinetics regulated uniform deposition ensured. Owing these advantages, Zn//Zn symmetrical cell exhibits remarkable cycling stability exceeding 2340 h (1 mA cm −2 1 ). The Zn//V 2 O 5 full also delivers stable for up 6000 cycles.
