In 1989, Shanshan Corporation was established by Zheng Yonggang in Ningbo, Zhejiang. Over the past 3 decades, Shanshan has developed from a single clothing business into a high-tech industrial group integrating lithium materials, polarizer and other industries.Since 2002, it has been listed in the Top 500 Chinese Enterprises for 20 consecutive years. In 2020, it ranked No.367 with sales of RMB 50.6 billion.

Shanshan has developed the new energy of lithium materials as one of its pillar industries. After over 20 years of continuous investment, it has set up production enterprises in Shanghai, Ningbo,Changsha, Baotou,Chenzhou, Dongguan, Shizuishan, Ningde, Quzhou, Meishan,etc. By producing cathode, anode and electrolyte materials for lithium-ion batteries, it has turned into the largest comprehensive supplier of lithium materials across the world.

In 2021, Shanshan localized high-end polarizers by acquiring LG Chem's polarizer business and establishing Shanjin Optoelectronics. Then, it built the globally four major production bases and delivered over 1700 patents. lt transcendentally developed localized polarizers with innovative technological capabilities and key solutions. In 2020, the polarizer production capacity of Shanjin Optoelectronics was 130 million square meters in 2020, ranking No. 1 in the world. lts shares in global market surpassed 27% especially the large-size polarizer above 65inch. With innovation, technological capabilities and key solutions, Shanshan is able to localize the production of high-end polarizers, becoming the world's largest polarizer manufacturer with leading technologies.

Based on industries, Shanshan focuses on the high quality developmentof new energy of lithium materials and polarizer. Through the introduction of first-class talents, continuous investmentin R&D, constantimprovement of technical strengths, and in-depth integration of industrial resources,Shanshan is committed to become a global leader in lithium materials and optoelectronic materials.
