Dual technology for high-quality lithium battery manufacturing escort

"At present, in the battery manufacturing industry, compared with the first-rate products of foreign companies, the main difference lies in the consistency and safety of battery performance in addition to the energy density. The fundamental way to solve these gaps is to ensure that the coating surface density is uniform, as well as the use of CCD technology for the whole process of battery manufacturing defects monitoring check. Zheng jian, chairman of zhejiang shuangyuan science and technology development co., LTD. (hereinafter referred to as "shuangyuan science and technology"), opened with his own views.

The dual technology just spent decades of time, the two core technologies have done sufficient research and practice, and "branch spread", its successful application in many industries.

ounded in 2006, shuangyuan technology co., ltd. is a comprehensive high-tech enterprise specialized in automatic detection and control system, machine vision application and other applications. In recent years, in the paper, metal foil, polymer film detection and control and other fields of research, bionic technology in the field of lithium battery/diaphragm detection and control also completed from 0 to 1 market competition.

It is understood that the dual chairman and general manager of zhejiang university of science and technology researchers, since the late 80 s the traditional industrial products quality control system (QCS), the production process of automatic collecting and distributing control system (DCS) technology research and development and industrialization application, especially in the field of sheet quality measurement and control accumulation formed a deep technical background and market. Shuangyuan science and technology co., LTD is a national high-tech enterprise, and it has been awarded "r&d center of sheet material quality measurement and control technology enterprise" by the government.

"Since the year before last formally entered the lithium battery industry, dual technology in the industry's visibility has increased rapidly, the performance is also rapidly climbing. This year's new customers include byd, Qingdao lishen, hubei mengshi, zhuhai guangyu, zte heergy, weihong power, suzhou xingheng, etc. The performance of lithium battery in january-may has increased 3-5 times compared with the whole year last year. Zheng jian said.

In fact, the main difference between domestic power batteries and foreign power batteries is not in electrochemical materials, but in the whole production process for the lack of refined management of product quality.

Zheng jian stressed that the cell factory to do a good job in the battery, not by the cell after the test and screening, but in the production process to ensure that the coating surface density uniformity; Products in the production of each link to use CCD technology to ensure that the appearance of no defects, no burr, winding size, etc., so that the quality of the cell produced by the basic guarantee.

Based on such a concept, dual-element technology, combined with its own mature and widely applied automatic closed-loop control technology in the field of sheet metal, has realized the full-width (longitudinal and horizontal) automatic detection closed-loop control of the coating surface density of sheet metal in the lithium battery industry, which has been highly recognized by battery manufacturers.

Zheng jian bluntly, compared with the constant temperature and humidity of the lithium battery production workshop, the production line of narrow width and slow speed, paper, film production conditions are much more harsh. There is often a high temperature, dust, water vapor and fog mixed, and the door is more than 3-5 meters, the speed is in the hundreds of meters per minute or even thousands of meters. Therefore, it is much more difficult to detect and control. Shuangyuan technology has been working in these industries for decades, and its products and teams have been recognized by users after being honed and honed, with its market share reaching 50-70%. It has also replaced a large number of first-class foreign systems, and its products are exported to the United States, Japan, Europe and other developed countries.

After entering the lithium battery industry, dual technology quickly completed the run-in between products and the industry. With stable and accurate measurement, efficient and reliable control, timely service response, the company's market share rapidly expanding. Dual technology also quickly found that the lithium battery industry is so far, and the company's series of products fit the highest degree of industry.

At present, the dual technology in the field of lithium electricity products including a partial density on-line detection of closed loop control system, the thickness of the plate after rolling laser online detection of closed loop control system, alignment plate coating defects on-line detection system, the size of the pole piece/diaphragm cutting online detection system, aligned sheet winding on-line detection system, pole piece end trimming quality online detection system, battery pole column laser weld defects detection system, the diaphragm surface defect detection system, the diaphragm thickness/coating thickness online detection control system, etc.

"The rapid growth of dual-element technology in the field of lithium battery also benefits from the company's investment of most of its research and development strength, technology and capital into lithium battery technology and market development. Zheng jian said that shuangyuan technology sees great opportunities in the development of lithium battery and has the confidence and ability to provide strong technical guarantee for the quality improvement, consumption reduction, labor saving and efficiency improvement of lithium battery enterprises.

Adhering to the business philosophy of "maximizing the benefits of users", shuangyuan technology has set up dozens of service branches at home and abroad, with a service team of more than 80 people. To ensure that the user's service requirements: immediate response, immediate processing. It is based on this concept and practice, dual technology services in all industries are well known.
