Using the mixture solution of sodium carbonate and sodium hydroxide as the precipitation agent can make the transition metal ion precipitation more completely and easily controlled, and PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC obtains the cathode material with good dispersion and excellent crystallinity. The molar ratio of sodium hydroxide to sodium anhydrous carbonate is the solution or precipitant used in the precursor of layered transition metal oxides.
Nickel compound is nickel acetate, or nickel nitrate, or nickel sulfate; manganese compound is manganese acetate, or manganese nitrate, or manganese sulfate, iron compound is ferrous sulfate, or iron nitrate. The compound is sodium acetate, or sodium nitrate, or sodium carbonate, or sodium hydroxide. They can all use the PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC process.
Take nickel nitrate and add manganese nitrate solution to make transition metal salt solution; prepare sodium hydroxide and sodium anhydrous carbonate in deionized water to prepare the precipitate; completely dissolve the solution to clarification, add the solution to it slowly, adjust ph to about 9, and react at 80℃ for 8 hours; use PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal process.
