The Development Course of Beijing Dang Sheng Material Technology Co., Ltd.

1992, electronic powder materials research group was established;

1993 the first bismuth oxide pilot production line was put into production;

1994 new products of ultrafine cobalt oxide and nickel oxide were successfully developed;

1995 ultrafine cobalt oxide and nickel oxide products were put into production, and Beikuang electronic powder material factory was established;

1996 annual output 150 tons bismuth oxide new line put into production;

1998, Beijing north mine electronic material development center was established;

1999 150 ton ultra-fine cobalt oxide production line was put into production, passed the ISO9002 quality standard certification, and established the lithium cobalt oxide research and development group;

In 200 1 year, Beijing Dang Sheng materials technology co., ltd was restructured and established to build a lithium cobaltate production line with an annual output of 150 tons;

In 2002, the first generation of lithium cobaltate 2# products was mass-produced, and the company's new lithium cobaltate products were put into the domestic market, successfully entering the cathode material industry of lithium batteries;

In 2003, 6#, 8# and 10# lithium cobaltate products were successfully developed and applied to the mobile phone lithium battery market. The production capacity of cobalt oxide is expanded to 500 tons/year;

In 2004, the comprehensive performance index of lithium cobalt oxide products reached the domestic leading level; The production capacity of lithium cobaltate was expanded to 960 tons/year, the production capacity of cobalt oxide was expanded to 800 tons/year, and the battery-grade cobalt oxide was awarded the national key new product certificate;

In 2005, it passed the extremely difficult quality management system certification of Korean high-end lithium battery customers; The capacity of lithium cobalt oxide is expanded to 1500 tons/year; 8# products have gained a good reputation in the market;

In 2006, we successfully developed Korean customers and took the lead in exporting products to international lithium battery giants.

In 2007, foreign capital from South Korea AMT and venture capital from three well-known domestic investment institutions, Shenzhen Venture Capital Group, Innovation Capital and Tongchuang Ye Wei, were successfully introduced, and Yanjiao Factory was completed and put into operation, becoming the largest supplier of cathode materials for lithium batteries in China. The capacity of lithium cobalt oxide is expanded to 3000 tons/year;

In 2008, we successfully developed new products of multi-materials and lithium manganate, and began to enter the power lithium battery market, with a new high sales performance.

In 2009, we successfully developed high-end lithium battery customers in Japan and entered the Japanese market. In the same period, multi-element materials and lithium manganese oxides received large orders from bicycles, BYD and Japanese customers. The company successfully completed the shareholding system transformation and changed its name to Beijing Dang Sheng Material Technology Co., Ltd.

20 10, Dang Sheng science and technology successfully landed on the growth enterprise market.
