Not only does the slitting machine have operating process requirements, but rewinders and napkin machines also have corresponding process requirements. Every employee who operates these machinery and equipment must undergo these trainings before they start to work, so as to reduce the probability of accidents. In production and processing, whether it is manual or mechanical operation, we are more concerned about its work efficiency, because good efficiency can not only increase productivity for the processing and m

The growing demand for batteries for energy storage and electric vehicles has prompted US companies to consider opening lithium mines in Nevada and other regions, which may increase US lithium production by 2 to 3 times in the next few years. Currently, there is only one lithium mine operating in the United States. The Silver Peak plant in Nevada is owned by Albemarle, which has a production capacity of 5,500 tons per year. The lithium mine in Nevada will go online in 2022 and will be developed by Lithium Americas

1. Humidity control <1%RH Purpose: to prevent water absorption during the winding process of positive and negative electrode sheets, resulting in zero voltage, self-discharge, and poor cycle performance; Method: Calculate the dew point value and the temperature value to obtain the temperature and humidity value; 2. Dust control &le;100,000pc/ft3 (detection particle size is 0.5um) Purpose: to prevent the dust from being involved in the pole group during winding, resulting in short circuit, overheatin

Both disc slitting and die cutting have tool wear problems, which easily cause process instability, lead to poor cutting quality of pole pieces, and reduce battery performance. Laser cutting has the characteristics of high production efficiency and good process stability. It has been used in the cutting of lithium-ion battery pole pieces in industry. The basic principle is to use high-power density laser beams to irradiate the cut battery pole pieces to make the pole pieces It is quickly heated to a very high tempe

Before the advent of laser technology, the battery industry used traditional machinery for processing. Compared with traditional mechanical processing, laser processing has the advantages of no tool wear, flexible cutting shapes, edge quality control, higher accuracy, and lower operating costs. It is conducive to reducing manufacturing costs, improving production efficiency, and greatly shortening new product molds. Cut cycle. Lithium batteries, as the core components of new energy vehicles, directly determine the

When the lithium-ion battery voltage is higher than 3.0V, it enters the second stage, the high current constant current charging stage (CCFastcharge). Since the lithium-ion battery has been pre-charged in the first stage, its state has been relatively stable (the purpose of the pre-charge stage can be understood in this way~ but it is not rigorous). Therefore, in the second stage, the charging current can be appropriately increased. According to different batteries, the current can vary from 0.1C to several C, wher

Balanced charging technologies commonly used in the balance principle of lithium-ion battery protection boards include constant shunt resistance balance charging, on-off shunt resistance balance charging, average battery voltage balance charging, switched capacitor balance charging, step-down converter balance charging, inductance balance charging, etc. When charging a group of lithium-ion batteries in series, ensure that each battery is charged equally, otherwise the performance and life of the entire group of bat

Dry Process of Fe-Li-ion Battery Separator The dry process can be subdivided into a uniaxial stretching process and a biaxial stretching process. The dry uniaxial stretching process is to prepare a high-oriented polypropylene or polyethylene film with low crystallinity by producing hard elastic fibers, and obtain a film with high crystallinity during high temperature annealing. The film is first stretched at low temperature to form micro-defects, and then at high temperature, the defects are pulled apart to form

Facing the development needs of the commercialization of power lithium batteries in the new energy era, major companies and manufacturers are eager to find a solution that can fundamentally "improve quality and reduce costs" to break through the application limitations of existing manufacturing and processing technologies .(High Speed Slitting Machine)       Among them, in the processing of the tabs of power lithium batteries, the bottlenecks of traditional hardware die-cutting t
