Maybe you do not have too much concern a few years ago, those around us appears to be no high-technology batteries, has been using imported steel shell to do. China’s battery production and consumption is a big country, the annual battery output of the world total output of about 1 / 3, to a large number of China’s annual imports of Japan and the United States for the battery of special steel shell.
In the 0.3 mm steel plate on to test their abilities
In previous years, the battery’s steel production process is the first strip steel punching into the battery, and then forming on the nickel plating for steel, the shortcomings of the process is the inside of steel, particularly depression on the part of the nickel-plated or not Non-uniform thickness of the coating. To solve this problem, a small number of ibm 08K8193 battery international manufacturers have begun to research and development “after the first red-plated” technology. The use of the technology products called electrodeposited nickel coating film (also known as deep-drawing steel cover nickel), which is used in electroplating nickel electrodeposition method will be in the low-carbon steel substrate surface and then deal with the proliferation of interface . This electro-deposition film is a new type of high-performance hp hstnn-ub02 battery casing material, as more sophisticated technology, a few years ago, domestic manufacturers can not produce, only outside Japan and Germany can produce.
“The reason why the domestic production of such material can not, one of the most important reason for this is made of red cells in the shell, the nickel coating material can not be synchronized with the basement extension of the nickel coating off easily.” Vice president of the Xiangtan University, Xiangtan University with the light Material Xinhua Institute of Physics, Professor Zhou Chun on the “Science Times” reporter, said: “As a high-performance battery casing material, its good to have deep-drawing performance (the depth of stamping). Stamping steel substrate after only 0.3 mm, which requires nickel Coating and substrate materials have a good extension of the apple m8511 battery synchronized performance. ”
From the beginning of 1994, Zhou Chun group has assumed 8 National Natural Science Foundation project, the follow-nickel steel deep drawing in-depth research, developed with independent intellectual property rights of the follow-up deep-drawing steel products, nickel, the main performance index In particular, corrosion resistance, deep drawing and so on, better than similar foreign products, changes in China’s high-performance hp pavilion zt1000 battery battery casing material of backward rely on imports.
“We are in the process of technology and mechanism found in the reach of nickel – iron between the spread of atomic energy reserves and high temperature conditions, the proliferation of two kinds of atoms to form iron – nickel alloy new phase in the formation conditions of the nickel – Iron alloy composite bonding is very strong and deep red when they do not meet the requirements of off. “Zhou Chun said.
The project team members, Xiangtan University School of Materials and optical physics professor PAN Yong said: “The material is an alkaline toshiba pa3356u-1brs battery a number of button batteries and rechargeable battery casings, by electro-deposition of nickel coating and low-carbon steel From closely integrated with good corrosion resistance and elongation, is a portable communications equipment, notebook computers, word processors, power tools, hybrid electric vehicle batteries used in the material of choice, the market has broad prospects. ”
Developed a complete set of production technology
With the development of information technology, high-performance batteries and battery materials, demand is growing. In June 2002, the project through the auspices of the Ministry of Education experts to the former International President of the Federation of Materials Research Society, Chinese Materials Research Society, honorary chairman of the Chinese Academy of Engineering, Tsinghua University professor, headed by Mr. Li Hengde Identification Committee to give Spoke highly of sony vgp-bps5 battery.
In the same year in December, from Hunan Province and khalid Investment Co., Ltd. Xiangtan University in Hunan Province set up a co-leader material Technology Co., Ltd., the deep-drawing steel nickel review the implementation of industrialization. “863″ project and the Science Foundation has funded the project, the results are successfully resolved from the laboratory to the production line in the process of encounter, such as “non-uniform thickness of the nickel Review” and “rolling deformation control,” and “deep Chong in the process of matching, “and so on, independently developed a complete set of production technology to produce nickel review of ibm fru 92p1137 battery the deep-drawing steel products have been authorized users and widely used.
After 3 years, they realized nickel review of the deep-drawing steel industry, have been completed and is currently the most wide of the line (1-meter wide line). In 2007, the company’s sales revenue 80,000,000 yuan, total production was 4,000 tons of products.
“Using the results of research projects, review the current nickel deep-drawing steel substrate by the Shanghai Baoshan Iron and Steel production, the shell of the red cell system developed by the Sichuan Changhong and production. In this way, so that mercury-free dell g5260 battery outside the high-performance green Shell in the full realization of China’s home-made. Changhong current battery, battery King Kong and several domestic and foreign brands of cell manufacturing, but also with our products. “Yong Pan said.
Improve the performance of the combination of knowledge
Since the 1990s, and film coating preparation and application of the academic community and the engineering is a broad one of the hot issue. “In particular, coatings and film spin-off failure and the interface there are many issues still vague, including the basic concepts of clarity, the characterization of refining indicators, evaluation criteria, as well as improve the interface to optimize the development process ibm thinkpad t60 battery battery , which to some extent, affect the theory Research and production of complement and further expand and deepen. “Zhou Chun said.
Electrochemical battery casings have been working in the field of research, Zhou Chun group successfully with its combination of solid mechanics, the crux of the matter is about to merge interface for performance issues. Put forward, such as the proliferation of interface layer, the laser thermal shock elimination of residual stress, and other new ideas. The results of their research papers at home and abroad, more than 20.
The group will be the basis of the practical application of research results, in the practical application process to obtain more in-depth study on the basis of the subject, this way students of science and technology innovation. In 2005, Science published a monograph of Zhou Chun – “material solid mechanics.” Changxu in the preface to the book when they wrote: “The materials in solid mechanics,” Professor Zhou Yichun condensation of more than 10 years of teaching experience, more cohesion and his guidance of graduate students in mechanical behavior of materials research. It will further promote the solid mechanics and materials science, combined with the cross sony PCGA-BP71 battery.
“The outcome was not only a good practical application, but also basic and applied research and promote each other. Through the project, we have further enhanced the understanding of the performance interface: the interface based on the combined performance of the fracture strength and fracture toughness characterization , The interface is more perfect; film will use the system, ductile-brittle easier to study the degree of hp ev088aa battery classification and evaluation of the bonding issue. “According to Zhou Chun disclosed that the respect due to the preliminary research done a good job, they further the National Natural Science Foundation Outstanding Young Persons of the Fund and the National Natural Science Foundation of the key projects funded
