摘要： 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.

摘要： Provided are a separator coating composition for a secondary battery including inorganic particles and a silane salt compound having a specific structure, a separator using the same, and an electrochemical device including the same. Specifically, provided is a separator coating composition for a secondary battery which implements adhesion between an inorganic material layer and a porous substrate without the need of including an acid and/or a polymer-based organic binder in a coating composition for forming the inorganic material layer on one or both surfaces of the porous substrate, and which does not need a separate acidic dispersing agent for dispersing the inorganic particles. A separator manufactured using the separator coating composition, and an electrochemical device including the separator are also provided.
