The two solutions are placed in the oil bath, heating and stirring to completely dissolve until clarification, using the solution as the parent liquor, heat up to 60~90℃, and then add the solution at a certain speed, adjust pH as the appropriate value for precipitation; After the conditions are stable, react at a certain temperature for 6~10h, aging, extraction and filtration, vacuum drying PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC to obtain the precursor solid powder;
The resulting precursor solid powder was pre-fired at 300-550℃ for 3-10 h; the excess sodium compound was dissolved in deionized water and absolute ethanol according to the stoichiometric ratio until the precursor was clarified, slowly stirred at about 50-90℃ until the deionized water and absolute ethanol were completely evaporated and dried under vacuum; PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal
The resulting solid powder sintering at high temperature to obtain the final sodium ion battery cathode material. The uniform co-precipitated complex precursor of nickel manganese iron was prepared by using a mixture of sodium hydroxide and sodium carbonate as precipitation agent, and then transferred to ethanol solution and reacted with sodium salt. After a simple high temperature reaction, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC removed iron to obtain the layered cathode material.
