In 2016, these enterprises in-depth layout upgrade lithium power battery performance material system
Publish：Sino Energy Corporation Time：2016-12-27
With the rapid development of new energy vehicles, power battery performance requirements continue to improve. Lithium enterprise a focus on energy density, safety, mileage and warfare is getting worse. Through battery material system upgrade boost power battery performance has become the industry consensus. In 2016, what are the depth distribution of lithium battery materials business?
1, Tian Qi Li industry and Ganfeng lithium hydroxide Beach
In September 5, 2016, Tian Qi Li industry announced that the company intends to raise funds of about 2 billion yuan RMB, invested in the construction of an annual output of 24 thousand tons of battery grade lithium hydroxide monohydrate project. The project is located in Western Australia City, Kwinana, the project construction period is 25 months, is expected to be completed in October 2018 trial production.
July 7th, Gan Feng Li (002460) to use its own funds to invest 303 million yuan annual output of 20 thousand tons of lithium hydroxide monohydrate project. The main products of this project include the production of battery grade lithium hydroxide monohydrate 15 thousand tons, 5000 tons of industrial grade lithium hydroxide monohydrate, the construction period of a year and a half.
2, national Xuan high tech and when science and technology force high nickel multi material
China Xuan tech November announcement, the company intends to raise funds of about 3 billion 600 million yuan investment to build power battery project, including an annual output of 10 thousand tons of high nickel cathode materials three yuan and 5000 tons of silicon based anode materials for projects; in October, when the rise of science and technology, the company has started high nickel materials with multiple layout generation has entered the car, in the test stage.
3, a material and capchem production of lithium salts LiFSI
In August, said in an investment providential materials research institutions, the company is expected by the end of this year will have 300 tons of production capacity of lithium salts LiFSI. In addition, this year also plans to increase the capacity of lithium salts to build 2000 tons / year.
July 13th, capchem (300037) intends to Changsha Xin Huayuan jointly invested 20 million yuan to set up Bo fluorine technology, investment in the construction of an annual output of 200 tons of bis (fluoro sulfonyl) imide lithium (LiFSI) project. Project implementation location in Hunan, Chenzhou, plans to invest 20 million yuan, construction cycle of 6 months, is expected to gradually put into operation by the end of 2016.
4, silicon based anode material industrialization approaching
Shenzhen snow product innovation of the year high capacity silicon based anode materials for lithium ion battery is the company with domestic universities to jointly develop, make use of their own advantages, using porous silica, and the stability of carbon material and preparation of high capacity silicon lithium battery anode materials with high capacity, long cycle, the efficiency for the first time in Kulun up to 95%, 500 weeks to maintain the material circulation capacity rate is more than 1000mAh/g grams.
At present, in addition to snow Shenzhen, China Xuan tech, Xingcheng graphite, Huzhou trunya, Shanghai Shanshan, are actively promoting the industrialization of silicon based anode. Shanghai Shanshan investment minister Yao Guiming introduction, nano silicon oxide and silicon silicon materials company is relatively mature and achieve mass production. Currently silicon oxide shipments up to 2 tons / month, nano silicon a few hundred kilograms per month / ton, has sent samples to Samsung, LG, Panasonic and other international battery companies.
5, Niumi technology and BenQ produced three membrane materials
Niumi technology company general manager Wang Zhichun said that the three layer composite diaphragm quality has been recognized by domestic and foreign customers, sales are increasing month by month. Current monthly capacity of 3 million square meters. After renovation, is expected to September 2016, production capacity will be raised to 5 million square meters / month, the main target market for power and energy storage areas.
BenQ director Su Yandeng introduced the three layer thermal circuit ceramic coated insulation film battery has won the Japan domestic customers, Tianjin, Wuhu Tianyi gateway customers in product certification.
6, water binder replacement PVDF
In December 9th, lithium engineering and Electric Vehicle Symposium special overseas, senior researcher ruiweng Group R & D center Ken Oh said, in the power battery energy density increase, anode material, diaphragm are facing some problems to be solved, such as anode material expansion problem is becoming increasingly apparent. The countermeasures are to develop new ruiweng water-based adhesive to improve the material system.
On the one hand, in order to enhance the energy density of the battery material system is being upgraded, many enterprises use lithium battery materials, water-based adhesive to improve material properties; on the other hand, the traditional PVDF is difficult to balance the conductivity and bonding performance, easy to produce pollution and other shortcomings, is also an urgent need to find new alternative adhesives. At present, in addition to ruiweng group, domestic zhongkelaifang, blue ocean Blackstone and other enterprises also launched water-based adhesive.
7, organic silicone as the representative of the rise of adhesive products
In order to improve the safety of power battery, the lithium industry chain enterprises are thinking of the solution. The application program is more mature is to use organic battery sealant, performance of the product is the largest when the individual cell leakage, explosion, fire, sealant can rapidly block flame propagation, to prevent the destruction of cells spread to other cells in the group, to provide protection for the safe operation of lithium battery. At present, Guibao science and technology, new material, new material. Lexus enterprises are actively exploring other silicone in addition to the application of silicone adhesive products in more power battery safety on.
