"textContent": "The present disclosure provides a preparation method of a composite current collector for a zinc secondary battery, a negative electrode plate, and a zinc secondary battery. The preparation method of the composite current collector for the zinc secondary battery comprises: 1) disposing a layer of carbon cloth between two layers of zinc mesh, thermally pressing the two layers of zinc mesh with the carbon cloth, and rolling the two layers of zinc mesh with the carbon cloth to obtain a pressed zinc mesh; 2) soaking the pressed zinc mesh in a graphene dispersion, then taking out and drying the pressed zinc mesh after soaking; and 3) coating two surfaces of the dried pressed zinc mesh with a conductive paste and drying to obtain the composite current collector for the zinc secondary battery. According to the composite current collector for the zinc secondary battery, the two metal layers are made by compositing the zinc mesh and tin, and the carbon cloth is disposed between the two metal layers, such that corrosion of a zinc negative electrode during use of the battery is reduced while ensuring the conductivity of the current collector, and the cycle performance of the battery is improved.",
