Ternary precursors are the main raw materials for manufacturing ternary materials. The production of ternary materials requires the use of an equal amount of ternary precursors. Nternary precursors currently account for approximately 55% of the cost of ternary materials. Previously, domestic cathode material manufacturers generally ignored the production and research and development of ternary material precursors, and most manufacturers directly outsourced the precursors for sintering.

Ternary precursors are the main raw materials for manufacturing ternary materials. The production of ternary materials requires the use of an equal amount of ternary precursors. Nternary precursors currently account for approximately 55% of the cost of ternary materials. Previously, domestic cathode material manufacturers generally ignored the production and research and development of ternary material precursors, and most manufacturers directly outsourced the precursors for sintering. According to industry insiders, precursors are crucial to the production of ternary materials because the quality of the precursors (morphology, particle size, particle size distribution, specific surface area, impurity content, tap density, etc.) directly determines the final sintering Physical and chemical indicators of the product. It can be said that 60% of the technical content of ternary materials lies in the precursor process. Material companies such as Dangsheng Technology also stated that precursors are very important for the production of ternary materials. The ternary precursors currently sold in the domestic market are mainly used in the field of small lithium batteries. Power ternary materials put forward higher requirements for their precursors. Require. In order to ensure the quality of power ternary material products and pass the testing of power battery customers, the company has begun to produce its own precursor materials. Therefore, whether from the perspective of cost or product quality control, the investment and development of ternary precursor materials is very promising, which is why companies have recently paid attention to ternary precursor materials. However, according to media reports, currently commercialized ternary precursors basically use the hydroxide co-precipitation method, that is, a mixed solution of nickel, cobalt, and manganese, precipitant, complexing agent, etc. are added to the reactor at the same time, and under certain conditions The ternary precursor (nickel cobalt manganese hydroxide) is synthesized below. The internal structure of the reactor and the control of the synthesis process are very demanding, which means that the technical threshold for ternary precursors is relatively high. It is understood that many material companies such as GEM adopt Japanese patented manufacturing technology and introduce a full set of Japanese equipment for the production of ternary precursor materials. The main domestic ternary precursor manufacturer: Ganfeng Lithium Industry: In 2013, 175 million was invested in a new ternary precursor material project with an annual output of 4,500 tons. After the new ternary precursor material project with an annual output of 4,500 tons is reached, the average annual increase Sales revenue is 346 million yuan, and the average annual net profit is 37.0593 million yuan. Red Star Development: The "Preparation Method of Ternary Cathode Material Precursor" applied by the company has obtained the invention patent authorization. However, the company has not produced the ternary cathode material and precursor for lithium-ion batteries. It is only developing and promoting ternary cathode materials as ternary cathode materials. And the basic raw materials of precursors (front-end products) - high-purity manganese sulfate, high-purity manganese tetroxide and other manganese products. Dangsheng Technology: The company specializes in the research and development, production and sales of lithium battery cathode materials, and is an industry leader in cathode material technology. The company's main products include multi-element materials, lithium cobalt oxide and other lithium battery cathode materials, as well as precursor materials such as cobalt tetroxide and multi-element material precursors. GEM: With Jingmen GEM as the main body, it plans to invest 95 million yuan to build a nickel-cobalt-manganese precursor material production line for power batteries with an annual output of 3,000 tons. At present, the company's ternary material production line mainly produces cobalt nickel manganese precursor materials. Dow Technology: Recently announced that it plans to use self-raised funds to invest in new energy materials projects. The company will set up a subsidiary with a registered capital of 50 million yuan as the main body of the project, mainly engaged in lithium-ion power battery ternary precursor materials, Recycling and reuse of lithium, nickel, cobalt, etc. for lithium-ion power batteries and research on new energy materials. It also stated that the company already has the production technology and talent reserve of ternary precursors. Henan Kelong Group: Founded in 1993, its main battery material products are spherical nickel hydroxide, spherical iron phosphate, lithium iron phosphate, multi-element lithium battery cathode materials, lithium manganate precursors, and ternary lithium battery precursors. Xinxiang Tianli Energy: Founded in 1983, its products are exported to South Korea, Japan and other countries. At the same time, the power battery ternary materials engineering technology center has passed provincial certification. At present, the company's main products are lithium nickel cobalt manganate ternary materials, lithium nickel cobalt manganate ternary precursors, and zinc powder. Ningxia Dongfang Tantalum Industry: Its main products are capacitor grade tantalum powder, tantalum wire for capacitors, spherical nickel hydroxide, ternary material precursors, etc. The company's 3,000-ton spherical nickel hydroxide project was officially put into production in 2010. In the first half of 2013, the development of ternary material precursors was completed and has been supplied in small batches. The annual production capacity is 2,000 tons.
