Abstract: In a method for recovering lithium hydroxide from a lithium secondary battery, cathode powder is prepared from a cathode of the lithium secondary battery. A cathode active material mixture is prepared by mixing the cathode powder with a calcium compound. The cathode active material mixture is reduced to form a preliminary precursor mixture. A lithium precursor is recovered from the preliminary precursor mixture. Therefore, a lithium precursor can be obtained with high purity without a complicated leaching process or an additional process, which result from a wet-based acid solution process.
