Nickel Hydride No. 5 battery

　　Research on the recycling and reuse of lithium, nickel, cobalt, etc. for lithium-ion power batteries and new energy materials

　　The ternary precursor is the main raw material for the manufacture of ternary materials. The production of ternary materials requires the use of the same amount of ternary precursors. The ternary precursors currently account for about 55% of the cost of ternary materials. Previously, domestic cathode material manufacturers generally ignored the production and development of ternary material precursors, and most manufacturers directly purchased precursors for sintering.

Previously, domestic cathode material manufacturers generally ignored the production and development of ternary material precursors, and most manufacturers directly purchased precursors for sintering. According to industry insiders, the precursor is very important to the production of ternary materials, because the quality of the precursor (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 is in the precursor process. Material companies such as Dangsheng Technology also stated that precursors are very important to the production of ternary materials. The ternary precursors currently sold in the domestic market are mainly used in the field of small lithium batteries, and the ternary materials for power have put forward higher requirements for their precursors. Require. In order to ensure the quality of power ternary material products and pass the test of power battery customers, the company has started to produce precursor materials by itself. Therefore, whether it is 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, the current commercialized ternary precursor basically adopts the hydroxide co-precipitation method, that is, the nickel, cobalt, and manganese mixed solution, precipitant, and complexing agent are added to the reactor at the same time. The ternary precursor (nickel-cobalt-manganese hydroxide) was synthesized under the following conditions.
