METHOD FOR MANUFACTURING METAL OXIDES FOR LITHIUM SECONDARY BATTERY USING GLYCINE SOLUTION

摘要

Method for producing a metal oxide for a lithium secondary battery using a glycine solution according to the present invention, dissolving nitrate and glycine solution to form a solution having a desired metal ion; Drying the solution as it is under a predetermined temperature for a predetermined time without filtering to obtain a mixture of metals of a desired equivalent ratio; Heating the metal mixture at a predetermined temperature for a predetermined time to obtain a cobalt tritium oxide precursor; And calcining the cobalt tritium oxide precursor at a predetermined temperature for a predetermined time to obtain a final metal oxide powder having a desired uniform phase.;According to the present invention, by sintering a solution in which various metal ions are evenly distributed at a low temperature, it is possible to produce a single-phase metal oxide having a uniform particle size distribution, a small particle size, and a uniform composition. In addition, a metal oxide having a composition that is difficult to manufacture a single phase oxide without impurities can be easily produced, and a process time is shorter and a process cost is significantly reduced compared to a conventional method.
