The invention provides an electrochemical test model for evaluating interface performance of grid and lead paste and a manufacturing method thereof. The manufacturing method comprises steps that: step1: lead alloy liquid is injected into a cooling model to manufacture a lead plate with a preset shape; step 2: the lead paste is disposed into a mould in a filled manner to manufacture the lead pastewith a preset shape; step 3: the prepared lead plate and lead paste in alignment are pressed by adopting a pressing piece, the lead plate and the lead paste are cured for 24-48 hours under the conditions that the temperature is 45-80DEG C and the humidity is 80-100%, and then are dried for 20-30 hours in the environment of 40-50DEG C to obtain the electrochemical test model for evaluating the interface performance of the grid and the lead paste. The invention is advantageous in that the structure is simple, and the performance of the grid and the lead paste interface can be conveniently and rapidly tested, so that the interface performance of the grid and the lead paste can be improved in a targeted manner, and finally, data support is provided for prolonging service lifetime of a lead-acid storage battery.
