The growth of dendrites and self-corrosion issues of Zn anodes in aqueous energy storage systems cause poor stability and cycling life. Hence, poly-quinol-phenylenediamine (PQA) is synthesized and constructed as the surface protective layer of bare Zn by blade coating, promoting the even dispersion of the electric field, inducing the uniform nucleation and growth of Zn. Consequently, PQA coated Zn (PQA@Zn) electrode demonstrates the improved cycling life of 450 h at 1 mA cm-2 and 220 h even at 5 mA cm-2 with the symmetric cells, superior rate capability and relatively lower overpotential at different current densities, far more than bare Zn foil. The surface morphology after cycles indicates that PQA coating restrains dendrites by leading to the deposition of Zn dendrites and decreasing the side effects by capturing the Zn2+. In brief, the PQA@Zn anode exhibited remarkable improvement in service life, cycling stability and rate capability, providing more possibilities for advanced energy systems.
