Lithium-ion battery pack, the diaphragm is the highest technical content, but also China is not fully realized the localization of components, each step forward in this regard are likely to bring a breakthrough domestic lithium battery products and their applications, and Xiamen University in the Air lithium (Luoyang) Co., Ltd. jointly undertake "high security functions battery separator technology development" project is such a product.

New membrane is a ceramic membrane function, using the substrate film surface treatment technology with inorganic ceramic powder dispersion technology to optimize the coating effect of ceramic powders, the establishment of coating thickness, ceramic type, particle size, surface characteristics and battery performance dose-effect relationship, summarize the ceramic membrane technology variation of parameters, but also has developed the current cut-off membrane characteristics and high heat resistance, technical indicators have reached the world advanced level. Not only for ordinary lithium battery, but also for highly consistent and meet the requirements of the monomer lithium polymer coating thickness of 3 micron aluminum oxide polyethylene membrane at 150 ℃ for 2 hours shrink rate is less than 2% performance is better than similar foreign products.
