In 2017, the diaphragm field was very popular, capital flocked, and new enterprises were endless. At the same time, the technology research and development of the diaphragm has not stopped.
Recently, Shanghai Top New Material Technology Co., Ltd. (hereinafter referred to as "Top New Materials") registers the high-rise Lithium Electric Vehicle Golden True, its annual innovation product - multilayer composite function diaphragm with lithium ion battery with heat resistance Sexual substrate, within 1 h at a high temperature of 200 ° C, the heat shrinkage ratio is less than 1%. At present, the above products are in the marketing promotion.
The top of the new material was built in April 2013, mainly engaged in the key materials of lithium-ion batteries - functionalized coating diaphragm business, focusing on the development and production of functional coating separators of high safety power cells. The company registration competition "annual innovation products" and "annual customer trust brands" two major awards.
At present, the high-rise lithium-electricity & electric vehicle golden award is in full swing. The "Golden Globe Award" has been successfully held since 2013, and the high concern of the entire lithium-industry industry and the active participation of enterprises in the industry in the industry have "lithium-cost Oscar".
➤ Annual Innovation Products: Multi-layer composite function diaphragm for lithium ion battery
With the improvement of the development level of the power battery technology, the polyolefin porous membrane bottleneck in the market is agglomerated: during the abnormal charge and discharge process, due to the temperature rise, the diaphragm contraction is deformable or broken, the battery electrode is directly in contact with the battery. A short circuit occurred, and the battery explosion occurred in extreme cases.
It is worth noting that this year this year's power battery market changes, the demand of ternary materials climbed, the diaphragm as a safe barrier of the positive and negative pole, and the performance requirements of the phosphate material are improved, especially for the compaction of the battery high power charge and discharge electric material. More stringent.
The multi-layer composite functional diaphragm of the top of the new material is used to heat resistant properties. PET, PIB and other polymer porous membranes are used as substrates, and heat resistance is heated at high temperatures at 200 ° C, heat shrinkage. The rate is less than 1%; the introduction of the closed cells allows the battery diaphragm to increase by more than 110 ° C, and the organic polymer microsphere is reduced by expansion, and the transmission channel of lithium ions is cut off. The safety of the battery.
The above multi-layer composite functional diaphragm has the following good performance: 1 coating common effect improves the contraction and short circuit of the polyolefin porous film; 2 The safety performance of the battery diaphragm is substantially improved, which can be applied to the power battery. Power charge and discharge; 3 cost reduction, improved security, and strong applicability.
➤ Annual customer trust brand: establishing a partnership with domestic and external diaphragm base membrane manufacturers
At present, the top new materials have established long-term business collaborations with many different diaphragm base membrane manufacturers at home and abroad. The main strategic cooperation companies in China include: Suzhou Jieci, Wuhu Mingkakati, Liaoyuan Hongmu and other manufacturers; at the same time agent Celgard, W-SCOPE diaphragm products.
In addition to strengthening cooperation with domestic and external base film manufacturers, the top of the new material is also developed with many high-end power battery plants in China, and the production of ceramic coating diaphragm supporting power batteries have been applied to electric bus on Malaysia, Netherlands and other countries. , Escort for lithium ion power batteries.
The main reasons for the top of the new materials have won the customer trust:
❶ Production strength: Top new materials Shanghai company has three high-precision diaphragm coating lines, and the current annual capacity capacity is 30 million flat. Taizhou Branch is equipped with 10 production lines, and 10 production lines in North China branch projects, and the production capacity can reach 300 million square meters.
The total area of the factory is 5,000 square meters. At present, there are 1800 square meters of high-level high-clean cleaning production workshops, with comprehensive product quality inspection capacity, with universal material intensity tester, high-precision thickness gauge, moisture tester, film gas permeability tester , Air clean purification tester, laser particle size tester, electrochemical workstation, and autonomous separator defect detector, etc.
❷ R & D strength: Top new materials have a multi-year scientific research and development team in the background of the lithium-ion battery industry, and R & D staff account for 20%. After four years of exploration and development, the company has formed a very mature research and development system; it has established a good cooperative technology development with Shanghai Jiaotong University and Nanjing University, which is an industrial and research project base of Shanghai Jiaotong University.
❸ Product strength: At present, the top of the new material is independently developing a variety of product lines, such as: low ion impedance high temperature ceramic coating diaphragm, bohemol ceramic coating diaphragm, polymer coating diaphragm, mixed gel coating diaphragm, etc. Among them, the new material is low ion impedance high temperature coating diaphragm. After use, the battery energy is improved, and the battery can be effectively improved by demanding acupuncture safety detection, effectively improve battery cycle performance and safety.
Looking for EV era power distribution
2017 high-rise lithium-electric board selection activities are in tension, there are nearly 150 listed lithium-industrial chain companies, and online voting is officially opened at 17 o'clock on November 27, and the ballot is until 24 o'clock on December 12. The final result of the award will be announced during the 2017 Lithium Economic Camp and Electric Vehicle Annual Meeting. , Read the full article, original title: [Dali Automation • Close] Top new material multi-layer composite function diaphragm for power battery
