Abstract

The invention relates to a method for material concentrating in a ternary precursor synthesis reaction. According to the method, a reaction vessel, a negative-pressure tank and a mother liquor tank are connected sequentially; a stirrer, a guide flow cylinder, a charging pipe, a nitrogen gas guide pipe, a liquid level meter, a clear-out pipe and a filter stick are arranged inside the reaction vessel; a vacuum pump is arranged at the top of the negative-pressure tank; and a centrifugal pump and a metering pump are arranged at the bottom of the mother liquor tank. According to the method, the problems of a ternary precursor synthesis reaction at present that concentrated particles are subjected to refluxing growth and the product is lost are solved. According to the method for material concentrating in the ternary precursor synthesis reaction, provided by the invention, reaction mother liquor can be directly drained outside the vessel, the problem of loss of the material particles is avoided, the particles are not required to be subjected to refluxing growth after concentration, and the problem that unaccepted products are produced due to secondary growth is avoided.

Description

technical field [0001] The invention relates to a method for concentrating materials, in particular to a method for concentrating materials in a ternary precursor synthesis reaction. Background technique [0002] With the rapid development of the field of battery materials, ternary materials have become one of the most widely used cathode materials due to their good cycle performance, large specific capacity, and high energy density. At present, the mainstream method for preparing ternary precursors in industry is the co-precipitation method, that is, nickel salt, cobalt salt, and manganese salt solution are used as raw materials, sodium hydroxide is used as a precipitant, and ammonia water is used as a complexing agent. The three are passed into the reactor together. Carry out the reaction, adjust the temperature, time, pH, stirring rate, solid content, etc. to control the shape and particle size of the product. [0003] At present, most ternary precursor manufacturers col...
