Hunan Huitong High-tech Energy Storage Materials Group Co., Ltd.

;;; Hunan Huitong Technology Co., Ltd. is a high-tech enterprise specializing in the research and production of high-purity ultrafine inorganic functional materials, with products covering manganese series, indium series, and bismuth series. The company has first-class manganese dioxide research experts in the industry, specializing in the research and production of various manganese dioxide (MnO2) and high-purity manganese salts for special purposes, including: high-purity manganese dioxide for tantalum capacitors, high-purity manganese nitrate, manganese dioxide for lithium manganese oxide power battery cathode materials, manganese dioxide curing agent for polysulfide sealants, and manganese dioxide for primary lithium manganese batteries. In addition, the company has established cooperative relationships with Central South University, Hunan University, Hunan Chemical Research Institute, Hunan Light Industry Research Institute, and other universities and research institutes, and has developed high-purity inorganic salt products such as indium oxide (In2O3), indium hydroxide (In(OH)3), indium sulfate (In2(SO4)3), indium chloride (InCl3), bismuth oxide (Bi2O3), bismuth hydroxide (Bi(OH)3), bismuth nitrate (Bi(NO3)3), basic bismuth nitrate Bi(NO3)2OH, and bismuth citrate.
;;; The company was founded in August 2007 and now has two domestic ** production lines for high-purity manganese dioxide and high-purity manganese nitrate, as well as the first domestic production line for manganese dioxide dedicated to lithium manganese oxide cathode material LiMn2O4, and a * professional production line for manganese dioxide curing agent dedicated to polysulfide rubber. It also has pilot production lines for bismuth salts such as bismuth oxide and bismuth nitrate, and indium salts such as refined indium, indium oxide, and indium hydroxide. The company adheres to the development orientation of high-tech industry, always upholds the principle of seeking survival by quality and development by innovation, and with advanced manufacturing equipment, excellent business philosophy, scientific management system, and a proactive and dedicated workforce, strives to become a professional leader in China's rare and precious metal functional inorganic materials!
