After the conditions are stable, the reaction at a certain temperature for 6~10h, aged, extracted and dried by vacuum, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal to obtain the precursor solid powder; the resulting precursor solid powder is pre-fired at 300~550℃ for 3~10h; sodium compound dissolved in the mixed solution of deionized water and absolute ethanol to add the precursor,
Slowly slowly at about 50~90℃ until the deionized water and anhydrous ethanol are completely evaporated and dried under vacuum; the resulting solid powder sintering at high temperature, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC removes the final cathode material of sodium ion battery. The problem to be solved is to solve the technical problem of the traditional co-precipitation method in the preparation of the precursor.
PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC Co-precipitation method, sodium hydroxide or ammonia water is commonly used as precipitation agent, and the pH value is adjusted to make the transition metal ions precipitate together to form the initial precursor material. The prepared cathode material has good dispersion and high crystallinity.
