In recent years, the hottest industry is not new energy lithium battery, so we all know that there are many processes in lithium batteries, today we will talk about a very important and technical process in lithium batteries, lithium battery separator production process and the application of supporting lithium battery separator material special mold temperature machine, to introduce to you what key role the lithium battery separator material special mold temperature machine plays in the production of lithium battery separator.
We all know that there is lithium battery separator wet technology in the production of lithium battery separator, which is important for the manufacture of polyethylene (PE) separator, and the wet technology involves the stretching of the separator in 2 directions, so it is divided into synchronous stretching and step-by-step stretching.
There has been an ongoing debate about which is more advanced, synchronous stretching or stepwise stretching. The controversy is reflected in product quality, efficiency, process adaptability and other aspects. From the comparison of the microscopic morphology of the product, the separator made by the synchronous stretching process has higher porosity, more uniform pore distribution and better thickness uniformity. At the same time, the synchronous stretching product has uniform strength, high yield, and theoretically better comprehensive performance.
So whether it is synchronous stretching or separate stretching, the temperature of the diaphragm is very important, at this time, our manufacturer will be very precise to control the temperature of the diaphragm drum, which generally uses a cold and hot machine to control the temperature of our drum.
With the rise of consumer electronics and new energy vehicles in recent years, the demand for separators, one of the important internal components of lithium-ion batteries, is also increasing. With the process upgrade of lithium battery separator film, according to the production process characteristics of the separator film, the special mold temperature machine for lithium battery separator material can achieve 0The temperature accuracy of 5 degrees can meet the needs of the production process.
