New Zebang develops new positive film-forming additives to improve the problems of FEC in high-nickel battery systems

The 2017 High-Tech Lithium & Electric Vehicle Golden Globe Awards, which is known as the “Lithium Oscar”, is in the process of being launched.

Xinzhoubang (300037) signed up for the Golden Globe Awards and competed for the annual customer trust brand and annual innovation technology/product award.

As a leader in electrolytes, Xinzhou State attaches great importance to technology research and development. At present, the company has 1,643 employees, including more than 301 R&D personnel, accounting for 18.32% of the total number of employees, 15 of them with senior professional titles and doctoral degrees, and nearly 100 with intermediate titles and master's degrees.

In 2014-2016, the annual R&D investment of Xinzhoubang was 34.464 million yuan, 72.788 million yuan and 10.44 million yuan respectively. In 2017 (as of October 31), the company's research and development has invested 77.9.70 million yuan. There are more than 50 research projects in the year, dozens of new products have been successfully transformed, and sales of new products account for more than 15%.

As of October 31, 2017, Xinzhoubang has applied for 301 patents, including 283 invention patents (25 foreign patents, 47 PCT patents) and 18 utility model patents, of which 87 were granted patents.

In terms of production, the company's lithium battery electrolyte capacity can reach 40,000T / year, the production has DCS automatic control system, from the cleaning of the packaging barrel to the filling and packaging to achieve full automation of the production process, in the production process, can reduce energy consumption, optimize production cost.

In terms of customer service, the company introduced the advanced SAPERP supply chain system, automatically optimized the scheduling plan, and established a green channel for emergency delivery, prompting quick response, efficient production, and the shortest delivery on the next day, which can meet the delivery schedule of different customers. Demand; established a professional customer complaints processing team, and established a CRM system, able to respond quickly, solve product problems, and expand horizontally and continuously.

The Gaogong Organizing Committee has learned that the new Zinc State Lithium Iron Phosphate Power Battery Electrolyte LBC338B86 and the ternary power battery electrolytes LBC420D72 and LBC3021C69 are widely used in many power battery customers; the lithium cobaltate high voltage electrolyte LBC3045M46 is in the digital Class customers are well known.

The company's international key customers are SUMSUNG, LG, SONY, Panasonic, NEC, MAXWELL, etc. Domestic key customers include BYD, Lishen, Guangyu, Guoxuan, Weihong, Fueng, Wanxiang, AVIC Lithium, Watmar, Silver. Long, Bick, Tianpeng, etc., become the most powerful competitors of the annual customer trust brand in the electrolyte field.

In order to maintain its dominant position in the field of electrolytes, Xinzhou State has developed new products forward-looking and has participated in this year's innovative technology/product awards with “High Nickel ternary/silicon carbon power battery electrolyte”.

According to Xinzhoubang, most of the current silicon-carbon electrolytes use high-content FEC to stabilize the SEI of silicon-carbon anodes, in order to improve the cycle performance of silicon-carbon anodes, but high-content FEC is easily replaced by high-nickel anodes or high-voltage NMCs. The positive electrode is catalytically decomposed, thereby deteriorating the high temperature storage performance and high temperature cycle performance of the battery.

Under this background, Xinzhoubang Company has independently developed a new positive film-forming additive LDY196, which can significantly inhibit the oxidative decomposition of electrolyte on high nickel positive electrode and high voltage NMC positive electrode, which can effectively improve the high content of FEC electrolyte in high nickel. Or high temperature NMC battery under low temperature and insufficient circulation problems.

A series of electrolyte products have been developed through a new positive film-forming additive LDY196, a negative film-forming additive VC, FEC, a lithium salt-type low-impedance additive, etc., which are used in a high-nickel positive/silicon-carbon negative power battery system. It can meet the requirements of 1000 cycles and can obtain excellent high temperature performance and low temperature performance.

This series of products is widely used in high energy density NCM811, NCA, high voltage ternary positive with silicon carbon negative power battery, has been widely used in high-end customers at home and abroad.
