CO-PRECIPITATION REACTOR FOR COMPOSING A BIG CONCENTRAT GRADIENT PRECURS AND THIS METHOD

摘要

A core solution consisting of a metal aqueous solution and a buffer solution and a shell solution to produce an opposite precursor having a center particle size of at least 18 microns among the concentration gradient type precursors continuously changing the metal composition from the center of the particle through the batch type coprecipitation reactor Two or more reservoirs provided so as to store or input the contents; A main reactor in which a metal aqueous solution is supplied by the operation of a metering pump and the coprecipitation reaction is performed in the reservoir; And an auxiliary reactor connected in series with the main reactor to supply a metal aqueous solution through a circulation pump to conduct a coprecipitation reaction, and a method for synthesizing the batch type coprecipitation reactor for synthesizing a concentration gradient type precursor precursor.
