Reserch And Development On Cathode Molding Equipment For Zinc-air Battery

With the rapid development of the world’s industrial and social economy, the highefficiency of resource becomes particularly important. In recent years, various types ofzinc-air battery have also been promoted for its efficiency, but the defect can not make itreal preparation to enter the market. This paper presents a pole piece manufacturingscheme.Manufacturing for zinc-air battery pole piece is the key technology. Preparation of thepole piece tow pole pieces forming and controlling the formation and the inside of the fiberbundle thickness of the pole piece pole piece core technology in the manufacturing process.Therefore, this paper focuses on these three areas, given the relevant principles andsolutions.First, the overall presentation of the pole piece and the relevant principles of theoverall process for preparing short answer describe the structure and working principle ofthe individual parts.Secondly, preparation of the pole pieces forming is part of homogenization and relatedstructural dynamics analysis. Abstract mathematical model homogenizing institutions,followed by a three-dimensional modeling software Solid Works resume simplifiedthree-dimensional solid model, and finally the simulation results analysis, and simulationresults are analyzed to find the key to its overall impact on both the quality and themovement of the performance, makes homogenizing molding device is verified andoptimized.Tow craft the ultimate goal is to make the pole pieces inside a uniform fiber bundlestructure, the establishment of an objective function to pull fiber structure according to theoptimization design method based on technical parameters and functional parameters;determine the boundary conditions, and obtain the optimal solution.Finally, thickness uniformity program rolling process was made. Pole piecethicknesses have great effect on zinc-air battery efficiency and life. We proposed athickness detection scheme using a laser detector, and it is designed with a closed loopcontrol system, which used as feedback control of the thickness for the rolling, and verifiedits controllable convergence. It laid the foundation for the pole piece rolling thickness consistency.
