Rechargeable Zn-ion battery is considered to be a promising new power source because of its low cost, high safety performance, environmental friendliness and high energy density. Zn-ion battery is the most competitive energy storage equipment in the future. At present, corrosion and passivation affect the development of Zn-ion battery. The growth of dendrites will pierce the diaphragm, resulting in a short circuit phenomenon and affecting the Coulombic efficiency of Zn-ion battery, severely limiting the development of Zn-ion battery. Herein, a simple strategy of depositing Zn on a 3D porous carbon aerogel (CA) by electrochemical deposition is proposed. The composite structure with low charge transfer resistance and a large electrically active area. The Zn-ion battery assembled by this composite material exhibits excellent electrochemical properties during the plating/stripping. The 3D Zn@CA anode shows lower polarization voltage, stable cycling stability and still achieve 100% Coulombic efficiency during the repeated deposition/stripping of Zn for about 13000 min. It has been proved that the material as a functional composite can effectively inhibit the growth of dendritic crystals, improve the electrochemical and cycling performance of Zn-ion battery.
