The invention relates to a battery plate manufacturing process, in particular to a water-based ion battery plate manufacturing process. The water-based ion battery plate manufacturing process comprises the following steps: tableting a mixture of active substances, a conductive agent, a bonding agent and a solvent; then, laminating with a current collector to form a battery plate which is 0.1mm-100mm in thickness. The water-based ion battery plate manufacturing process has the advantages of less production equipment, simple process, high production efficiency, high material utilization rate, easiness in plate molding, and easiness in control of the surface density and the thickness, and the service life of a battery is prolonged effectively.
