On December 10, 2019, OCSiAl, the world's largest single-walled carbon nanotube producer, officially opened its first technology R & D center in China in Shanghai. Nearly 200 experts and elites who applied single-wall carbon nanotube technology from various industries participated in the opening ceremony, including CATL (Ningde Times), Haiyi, Shenyang East, Lishen Battery, Kusumoto Chemicals (Nanmu Chemicals Co., Ltd.) and so on. The establishment of TUBALL Shanghai Center is of great significance for the future development of China's battery industry.
TUBALL Shanghai Technology R & D Center created by OCSiAl is located in Pudong New Area, Shanghai, covering an area of 1,260 square meters, including 12 laboratories and 150 sets of equipment, covering the five main applications of TUBALL products-batteries, plastics, coatings, composite materials and elastomer At the same time, supporting a series of product quality testing equipment. With the establishment of TUBALL Shanghai Center, OCSiAl will provide customers with faster and more efficient technical support and services, and develop customized solutions for customers to maximize meet customer needs.
OCSiAl is the world's largest manufacturer of single-walled carbon nanotubes, and has realized the industrial application of single-walled carbon nanotubes in lithium-ion batteries with an annual output of 60 tons. Its core product, TUBALL single-walled carbon nanotubes, is an additive that brings super-conductivity to lithium batteries, and has proven to be the most cost-effective silicon anode solution.
TUBALLBATTH2O developed by OCSiAl is an aqueous conductive dispersion containing single-walled carbon nanotubes that can be used for silicon negative electrodes. The single-walled carbon nanotubes in TUBALLBATT products are ultra-fine and stable. This means that they can be simply mixed and combined with the silicon anode material during the homogenization of the battery slurry. The results of customer experiments show that after adding TUBALLBATTH2O, the cycle life of lithium batteries containing silicon anodes is significantly improved, and it can still maintain more than 80% of its capacity after 1,000 cycles.
Dr. Zhong Ze, Senior R & D Manager of CATL Battery, addressed the opening ceremony: "Single-walled carbon nanotubes can greatly improve the cycle life of the battery and reduce the internal resistance of the battery cycle, which is a great help in the battery field. Shanghai TUBALL Center Our future material development and application in the battery field will be of great help, because we can work together to do more projects, and some new R & D and new applications of related materials can be carried out faster. "
Mr. Liu Zhijun, general manager of Shanghai Haiyi Technology & Trade Co., Ltd. delivered a speech at the opening ceremony: "The expansion of the technology application of single-wall carbon nanotubes will affect all aspects of our lives and make our lives more environmentally friendly, energy efficient, efficient and natural. We It is believed that the high-standard TUBALL Shanghai Technology R & D Center, which gathers domestic and international professionals, will provide more powerful help for the rapid expansion of single-walled carbon nanotube product applications and the rapid take-off of OCSiAl. The technical results born from this will allow Our lives are getting better. "
