摘要

Natural minerals are characterized by their variety, low cost, and environmental friendliness. However, actually, low-end exploitation plays a master role in the use of minerals, and the utilization of high-appended benefits needs to be strengthened. In recent years, the lithium-ion batteries have been extensively utilized in electric automobiles and most mobile electronic devices. On the basis of realizing the high value-added utilization of mineral resources, this paper combines pyrolusite with nickel-rich ternary lithium-ion battery LiNi0.6Co0.2Mn0.2O2. Firstly, the manganese element is extracted by sodium sulfite reduction leaching of pyrolusite, and then, the nickel-rich ternary cathode material is prepared by co-precipitation process using manganese-rich filtrate as raw material. Under optimal experimental conditions, the material’s initial discharge-specific capacity exceeds 185 mAh g−1, with a capacity retention rate exceeding 98% even after 200 cycles. It not only satisfies the development of basic minerals, but also realizes the low-cost preparation of nickel-rich ternary lithium-ion battery.
