Problems solved by technology

[0005] To this end, the embodiment of the present invention provides a battery plate manufacturing process, by first using 3D printing fusing deposition technology to print the printing substrate on the positive and negative current collectors, and then using the 3D layered entity manufacturing technology to make a complete battery positive and negative Pole, battery positive and negative materials are highly interlocked with the foil, and at the same time, no trace of adhesive is used, powder will never drop, and the material has better dispersion. At the same time, the ion migration resistance formed by the traditional process due to the adhesive will be removed. The charging and discharging ability of the battery is more excellent, which can eventually reduce equipment investment, simplify the manufacturing process, and greatly reduce the manufacturing cost, so as to solve the problems of high cost, cumbersome process, low processing efficiency and general charging and discharging ability in the existing technology

Abstract

The invention discloses a battery pole plate manufacturing process, and particularly relates to the technical field of battery processing. The battery pole plate manufacturing process comprises the steps of S1, mixing polylactide, styrene resin, nylon, polycarbonate, polyether-ether-ketone and carbon fibers to obtain a printing base material; and S2, printing the printing base material obtained inthe step S1 on positive and negative current collectors by using a 3D printing fusing deposition technology. According to the invention, the printing base material is printed on the positive and negative current collectors by using the 3D printing fusing deposition technology, then a complete battery positive electrode and a complete battery negative electrode are manufactured through a 3D layered entity manufacturing technology, the positive and negative electrode materials of the battery are highly embedded with the foil, a trace amount of adhesive is not used, powder never falls off, the material dispersibility is better, the ion migration resistance formed by the adhesive in the traditional process is removed, the charging and discharging capacity of the battery is more excellent, finally, the equipment investment can be reduced, the manufacturing process is simplified, and the manufacturing cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of battery processing, in particular to a battery pole plate manufacturing process. Background technique [0002] A fuel cell is a chemical device that directly converts the chemical energy of fuel into electrical energy, also known as an electrochemical generator. It is the fourth power generation technology after hydropower, thermal power and atomic power. Since the fuel cell converts the Gibbs free energy in the chemical energy of the fuel into electrical energy through an electrochemical reaction, it is not limited by the Carnot cycle effect, so the efficiency is high; in addition, the fuel cell uses fuel and oxygen as raw materials; at the same time There are no mechanical transmission parts, so there is no noise pollution, and the emission of harmful gases is very small. It can be seen that from the point of view of saving energy and protecting the ecological environment, fuel cells are the most prom...
