Localization of lithium battery separator -Lithium - Ion Battery Equipment
Power lithium-ion battery breaks through the separator
my country Chemical Industry News November 15: At present, the market supply of lithium-ion batteries in my country is seriously insufficient, and most of the market is occupied by products from the United States and Japan, resulting in high prices. After more than a decade of research and development, our production gap is now industrialized, breaking down barriers to foreign domination of our market. At the 2010 (5th) World Power Li-ion Battery Technology and Industry Development Forum held last week, Yang Shuting, head of Henan Xinxiang Green New Energy Data Co., Ltd., said.(Lithium - Ion Battery Equipment)
Yang Shuting said that the company has formed a production capacity gap of 60 million square meters, but the product is still in short supply, so the company decided to add a production line with an annual output of 100 million square meters, and the project is currently under construction.
The reason the barrier is so technical is that it is difficult to punch holes. At present, the barrier layers in the world mainly include single-layer polypropylene (PP) nanoporous membrane, single-layer polyethylene (PE) nanoporous membrane, and PP/PE/PP three-layer composite nanoporous membrane. Grimm gained the ability to disrupt monolayer PP microporous membranes. The company chooses the dry biaxial stretching process, that is, adding an organic crystal nucleating agent to the polypropylene, using the density difference between the different phases of the polypropylene, in the process of transverse and longitudinal stretching, the crystalline form is transformed into micropores. The thickness of the gap can reach 15~60 microns, which is especially suitable for power lithium-ion batteries.
Simply put, an isolation is a porous plastic film. According to Yang Shuting, lithium-ion batteries are mainly composed of positive electrodes, negative electrodes, electrolytes, separators and shells. The gap serves to prevent a short circuit between the positive and negative electrodes of the lithium-ion battery, and to supply a lithium-ion transport channel during charging and discharging of the lithium-ion battery. The purpose of the separator determines the capacity, internal resistance, cycling, storage and safety of lithium-ion batteries. This notch is the state-of-the-art for lithium-ion battery components, so it accounts for about a third of the battery's cost. He said that with the country's strong support for the development of electric vehicles, my country's demand for power lithium-ion battery data will explode in the next few years. By 2012, the demand for lithium-ion batteries for electric vehicles will increase tenfold, reaching about 400 million square meters per year. However, due to the high content of estrangement skills, the home has not yet been localized.
