LITHIUM-CONTAINING IRON OXYHYDROXIDE AND METHOD FOR PRODUCING NONAQUEOUS ELECTROLYTE ELECTROCHEMICAL CELL CONTAINING SAME

摘要

A method for producing a lithium-containing iron oxyhydroxide is characterized in that a complex solution wherein metal lithium and a polycyclic aromatic compound are dissolved in a solvent is brought into contact with iron oxyhydroxide so that lithium is absorbed in iron oxyhydroxide. Also disclosed is a method for producing a nonaqueous electrolyte electrochemical cell using an electrode containing a lithium-containing iron oxyhydroxide obtained by such a method. By this method, there can be obtained a nonaqueous electrolyte secondary battery having a large discharge capacity and good cycle performance.
