| The research and development of Nickel-hydrogen power battery has been one of the hot in a series of major international science and technology development plan. But, the research and development of Preparation of the cell plate technology and its equipment are constraining nickel-hydrogen battery developing. In response to this critical problem, the Advanced Manufacturing Technology of Northeastern University and Shenyang Institute of Automation and battery equipment of Dongpeng Ltd. jointly developed the preparation of nickel-hydrogen battery plate-automatic production line, which is a priority to improve the level of the entire battery industry and to improve its international competitiveness of the market in our country.This paper introduces the preparation of nickel-hydrogen battery plate technology, choice of background and history of the development and the situation of research at home and abroad. And it expounds the characteristics and application prospects of Nickel-hydrogen power battery technology and its equipment, we carries out a more systematic study on the key of technologies and equipment of the nickel-hydrogen battery plate preparation. Through studying, the main conclusions are drawn as follows:(1)It has shown through studying the class classification of cathode substrate that Volume of nickel-like foam are suitable for automated production; Chemical Plating,vacuum sputtering of nickel foam have a smooth surface through Scanning electron microscopy with analyzing. And the use of impregnated foam nickel coated graphite surface is very rough, but there is a considerable number of closed-hole, the hole on the plate coating has an adverse impact. And it studied the tensile strength of nickel foam noodle instead of the relationship between density. It has shown through studying the thickness distribution coefficient (TDR) of foam nickel coating that if the TDR value was large, the internal nickel foam was more fragile. At winding plate, it is easy to fracture in the plate rolling process, and the nickel foam can easily cut tendons, but it also cause the battery to increase resistance.(2) It has shown through studying the process of pre-deformation in Cathode substrate by pressure that at the three types of substrate, the elongation of nickel foam was the largest, followed by composite materials, fiber nickel was minimum. Focusing on the foam nickel which was widespread used of plate against battery power in the process of preloading the force and deformation are analyzed and concluded that the pre-roll diameter change on the positive extension of the rate of substrate has little effect(3) It has studied a variety of technology that power battery positive plate that reserve road of collector substrate solder. Discuss about weld mechanism of active substances of the high-pressure water washing and vacuum technology to clear Absorption(4)It was shown through analyzing the impact of Cathode plate coated factors that the pass and porosity of Nickel foam was no more than a small effects on plate coating. Particle size and shape of Ni(OH)2 was more than a great effect on the plate coating. Viscosity and mobility of slurry was more than a great effect on plate coating. If the slurry viscosity is too low or too high, it will lead to inadequate sizing plate.(5)Through analyzing and studying the variety of coating methods of Cathode plate,and proposed a method of Constant pressure and precision coating technology刮涂complex processes in order to completely resolve the problem浮粉surface plate, resolve the uniformity of density problem that how to detective electrode active substance coating.(6)Through studying the process of Cathode plate rolling, it was set up the relationship between the thickness of the equation, which is based on the before and after of plate rolling with radius of the roller. It has shown through studying the plate deformation mechanism of Rolling. Roll diameter which is changed on the plate, has a great influence on the elongation. Stress which is changed on the plate has a little influence on the elongation. The effect of elongation which is caused by ratio of Stress, that the relationship between the two are exponent, in general, the greater of the stress of ratio m is, the greater of elongationδis.(7) Focusing on process of slurry combined, we set up a fuzzy control model, and set up the best mixing speed and the best time of fuzzy automatic sizing of hybrid system of fuzzy control rules. Use experts in intelligent control to control the process of which is difficult and complicated in drying the coating. Adopt Intelligent Control experts, and established the production process of knowledge base plate structure; Use the nonlinear neural network control system to control the thickness of plate rolling(8) It is proved that the theory of nickel hydrogen battery positive plate preparation process is correct. And structure is reasonable, stable and performance is reliable after the actual operation of production equipment... |
