Prospects for multi-level utilization and recycling of power lithium batteries:     According to statistics, the cumulative sales of new energy vehicles in China in 2017 reached 1.8 million, and the market sales in 2018 are expected to be around 1 million. The service life of power batteries is generally 5 to 8 years. Starting in 2019, my country's power batteries will enter a large-scale obsolescence period. By 2020, the annual scrap volume of China's automotive power batteries is expe

The general process of the production process of ion battery pole piece is: active material, binder and conductive agent are mixed to prepare slurry, and then coated on both sides of copper or aluminum current collector, after drying, the solvent is removed to form dry pole piece and pole piece particles. The coating is compacted and densified, and then cut or slit. The equipment used to produce lithium batteries is a professional die-cutting machine for lithium battery pole pieces. Mainly used for forming positive

There are three main reasons for the generation of pole piece burr dust: 1. The punching method; 2. The structure of the punching die; 3. The material and processing accuracy of the punching die.       Pole piece burr refers to the stretching and bending of the section base material produced by the punching of the pole piece. The general standard for pole piece burrs in the industry is Vh≤15μm (calculated based on the collector surface); Vk≤15μm (calculated based on the edge of

Experts believe that these seven points are not only the buyers should pay attention to, but also the problems that the die-cutting machine must solve when manufacturing equipment. How to choose a die-cutting machine with high speed and high precision? Recently, Chai Sanzhong and Cheng Ganghu of Xi'an University of Technology and Zhang Xuansheng of Beijing Institute of Graphic Communication have provided answers to the industry. That is to say "seven looks".(High Speed Slitting Machine) Take a loo

In the die-cutting process, it is more common for the blade to be unfavorable or the product has burrs when the die is in use. In addition, die-cutting engineers are a little confused about the choice of die-cutting engineers, because most of the die-cutting suppliers say to die-cutting engineers, "What kind of Japanese DC53 steel do they choose for their die-cutting molds? SK-5 made an etching mold, and said how good his equipment is, etc. "This makes it difficult for the die-cutting engineers to judge

The main function of the lithium battery stacking machine is to cut the positive and negative electrodes into individual pieces, the diaphragm is stacked in a zigzag shape, and the positive and negative electrodes are stacked in turn, separated by the diaphragm. Or, the positive electrode sheet, the separator, and the negative electrode sheet are sequentially stacked to form a battery cell, and the battery cell is positioned and assembled on the second layer of diaphragm, and the second layer of diaphragm is wound

Lithium battery die-cutting machine brands in various countries have different starting times. Although Japan and South Korea’s die-cutting machine related equipment have been involved earlier, after several years of domestic manufacturers’ efforts to catch up, they have been very close in efficiency. In terms of stability, domestic brands and domestic brands Japanese and Korean brands are almost the same.(Lithium - Ion Battery Equipment)       The domestic lithium battery indu

Mold maintenance is divided into primary maintenance and secondary maintenance. Mold primary maintenance. The first-level maintenance of the mold refers to the daily maintenance of the mold by the operator during production, and the main content is cleaning(High Speed Slitting Machine) Rub, lubricate and inspect. The secondary maintenance of the mold refers to the regular systematic maintenance of the mold based on the technical status and complexity of the mold. Primary maintenance of mold 1. Maintenance during

With the end of the 2018 interim report disclosure period, several domestic power lithium battery head companies such as CATL, BYD and Guoxuan Hi-Tech have all handed in their transcripts for the first half of 2018. Judging from the situation of several leading companies, many companies in the industry have shown the common feature of "increasing revenue and reducing profits" in the past six months.(Lithium - Ion Battery Equipment) On the one hand, new energy vehicles are in a period of great development
