N2 - Aqueous zinc ion batteries (ZIBs) have received widespread attention. Due to serious corrosion of Zn anodes and dendrite growth, further application of ZIBs is hindered. Herein, an artificial mixed electronic-ionic conductive coating layer (Alg-Zn + AB@Zn) consisting of zinc alginate gel (Alg-Zn) and acidified conductive carbon black (AB) is introduced on the surface of Zn. The as-prepared mixed coating not only provides more Zn nucleation sites, but also effectively reduces the nucleation overpotential of Zn. Therefore, the Alg-Zn + AB@Zn symmetrical cell can stably maintain an extremely low voltage hysteresis. Furthermore, Alg-Zn + AB@Zn endows the Zn/AC full cell with excellent cycle stability, especially at high current densities. A capacity retention rate of nearly 100% can be achieved over 10 000 cycles at 10 A g−1, and 16 000 cycles at 20 A g−1, superior to those of the other reported Zn/AC full cells at high current densities, to the best of the authors' knowledge.
