An announcement was issued at noon on September 29. The DS Tech company applied for an invention patent for "a method for preparing a lithium-ion battery lithium-rich Mn-based cathode material precursor" applied on December 29, 2011. It has recently won an invention issued by the State Intellectual Property Office. patent certificate.
According to the announcement, the invention patent discloses a method for preparing a lithium-ion battery-rich lithium-manganese-based cathode material precursor. Compared with lithium cobaltate, lithium iron phosphate, and ternary materials, the lithium-rich manganese-based cathode material has a higher The specific capacity is considered to be one of the ideal cathode materials for long-range electric vehicles in the future, and the synthesis process of lithium-rich manganese-based cathode materials precursors largely determines the electrochemical performance of lithium-rich manganese-based anode materials. The invention uses a co-precipitation method to prepare a lithium-rich manganese-based anode material precursor with high density and sphericity and good fluidity, with high yield, simple process, and environmental friendliness, and helps to realize large-scale production of lithium-rich manganese-based anode materials. produce. At present, the invention patent has not been applied to the company's actual production.
