| titleOfInvention | A kind of reactor and method for preparing lithium ion battery cathode material precursor |
| abstract | The invention discloses a reaction kettle for preparing a lithium ion battery cathode material precursor, comprising a shell, a stirring device, a first air inlet pipe, an air outlet pipe, a feeding pipe and a filter plate. The plate divides the shell into a reaction zone and a grading zone; the stirring blade is in the reaction zone; the first air inlet pipe leads into the reaction zone, and the outlet pipe opening is arranged at the top of the shell; the bottom of the reaction zone has a bottom discharge pipe; There is a side wall discharge pipe. The invention also discloses a method for preparing a lithium ion battery positive electrode material precursor by the reaction kettle: the raw materials are introduced into the reaction zone under stirring; 0.02-0.15MPa nitrogen gas is introduced into the first air inlet pipe to press part of the precursor small particles into grading area. In the reaction kettle and the preparation method of the present invention, the precursor with the required particle size is separated and continued to grow during the reaction. Precursors with different particle sizes are prepared from filter plates with different pore sizes, and then mixed in proportion, so that the particle size and particle size distribution of the lithium-ion battery cathode material precursor are controllable. |
