| titleOfInvention | Synthesis Method of Nano-Chemical Manganese Dioxide by Recycle Process for Cathode material used in Secondary Battery |
| abstract | The present invention is crushed into the manganese dioxide seed of nanopowders industrial manganese carbonate (MnCO 3) a powdery manganese dioxide seed (seed-MnO 2) the primary particles are nano-sized (nano size) of the manganese dioxide seed after making a heat treated (CMD), which is used as a precursor of the cathode material of the secondary battery, is homogeneously grown on the surface of the seeds of the nano-manganese dioxide, and is firstly prepared CMD1). At this time, the separated reaction solution is recycled to obtain a powdery primary manganese dioxide (CMD1), and utilized as a mother liquor for the production of secondary and tertiary manganese dioxide (CMD2 and CMD3), whereby manganese dioxide The present invention also provides a lithium secondary battery which can be used as a precursor of a cathode material of a lithium secondary battery and can be used as a cathode material, (CMD) for a cathode material of a secondary battery using a recycle process so that the discharge efficiency can be further improved, and nanodioxide (CMD) produced by the method. A) a step of maintaining manganese carbonate for industrial use at a temperature of 300 to 450 ° C for 30 minutes to 10 hours under an air atmosphere and then cooling to produce manganese dioxide seed; b) In the attrition mill pulverizer, the manganese dioxide seeds produced in the step a) are mixed with a large number of ceramic balls for friction grinding with respect to 20 to 30 wt% of manganese dioxide, 62 wt% and distilled water in an amount of 8 to 18 wt%, pulverizing the powder, drying the pulverized material with the ceramic balls removed to produce powdery manganese seeds; c) Using the agitator, the pulverized manganese dioxide Mixing the seed and the sulfuric acid at a constant temperature in the agitator; d) Mixing manganese sulfate and distilled water using a stirrer and mixing at a constant temperature in the stirrer; e) adding sodium chlorate and distilled water using a stirrer, and mixing the mixture at a constant temperature in an agitator; f) mixing the mixture of step c) and step d) at a constant temperature; g) mixing and stirring the mixture of step e) with a mixture of step f) to a predetermined temperature, and separating the mixture of CMD1 and the reaction filtrate firstly in a solid-liquid separator; h) mixing and stirring the mixture of step c) and step e) at a constant temperature in the solid-liquid separated reaction filtrate at a predetermined temperature, and separating the mixture into CMD2 and reaction filtrate by solid-liquid separation in a solid-liquid separator; i) recycling the reaction filtrate separated in the solid-liquid separation step h) to the filtrate in step h) again, mixing the mixture of step c) and step e) again at a constant temperature, Stirring the mixture, and subjecting the mixture to solid-liquid separation in a reaction liquid with CMD3 in a third liquid phase separator. |
