Nanofiber battery separator: Jiangxi Cai Xian Nanofiber Technology Co., Ltd. (company 65.3 1%), a holding subsidiary of Changchun Gao Qi, plans to build a PI nanofiber battery separator project with an annual output of 200 million square meters. The total investment of the project is about 600 million yuan, and it is expected to reach production in 20 14 years. The investment of this project is based on the development status and demand trend of power battery industry at home and abroad, as well as the strategic measures of the enterprise's own development demand, and cultivates new profit growth points. The planned production capacity of the first phase of Jiangxi precursor polyimide nanofiber power battery separator project is 40 million square meters/year. It is estimated that the trial production will be put into operation in September of 20 12, and the first-phase design capacity can be reached in the middle and late period of 20 10000. During the trial production, it is estimated that the daily production capacity will reach 1000 square meters. The company's PI diaphragm has passed the test of the national authoritative organization, and is currently being tested with four leading enterprises in military industry and civil use. Test products include disposable lithium batteries and rechargeable lithium batteries. The test results show that the battery has been charged and discharged at 4C rate for more than 9500 times, and the battery remains intact, and the capacity remains above 62%.

The progress of the project "Development of Functional Diaphragm Technology for High-safety Power Battery" supported by the National High-tech Research and Development Plan (863 Plan) jointly undertaken by Cheng Fei Integrated Subsidiary AVIC Lithium Battery (Luoyang) Co., Ltd. is basically true. According to the above-mentioned cooperative development project with Xiamen University, AVIC Lithium Battery began to build an industrial test line of ceramic functional diaphragm technology in early 20 12, with a total investment of100,000 yuan, which was rebuilt in the existing factory building of AVIC Lithium Battery. As of June 20 13, the pilot line of this project has been initially completed, and the development of related formula curing, sizing, coating and cutting technologies has been completed, forming an annual production capacity of 3 million square meters of ceramic functional partitions. On this basis, the design, trial production and testing of ceramic separator batteries have been carried out, and four functional separator products with different specifications have been developed, a series of which have been put into use in various metal shell batteries.
Large Rubber-Plastic (600346) Lithium Battery Diaphragm Equipment
The production line of lithium battery ion diaphragm has been mass-produced. The company announced on February 20 13 that it signed a large order for lithium battery diaphragm with Hebei Jinli New Energy Materials Technology Co., Ltd., amounting to 68.5 million yuan.
Haoningda (002356)
It is planned to purchase 900 million yuan of Henan Ito to enter the lithium battery separator, and it is planned to purchase 0/00% equity of Henan Ito/Kloc, with a transaction amount of 91000,000 yuan. At the same time, it is planned to raise matching funds of no more than 250 million yuan from the non-public offering of shares of Chen Zhixiong, Liu Bingbing and Anton. Ito is a leading professional lithium ion battery separator manufacturer in China. At present, its main products are nano-porous membranes and ceramic-coated membranes. The "stretching-retracting" process for manufacturing nano-porous diaphragm is the first in China and has won the national invention patent. Ito is also one of the first enterprises in China to realize mass production of ceramic coated diaphragm, which is more suitable for power batteries and industrial energy storage applications.
