Abstract
The present invention is concerned on the manufacturing process of Li-contained nickel oxyhydroxide obtained by a lithium absorption process with contact reaction between nickel oxyhydroxide and a solution obtained by dissolving metallic Li and polycyclic aromatic compounds in a solvent. Moreover, the nonaqueous electrolyte electrochemical cell using Li-contained nickel oxyhydroxide active material obtained by this manufacturing process is able to be high performance with a low manufacturing price by its simple process compared to the existing process by electrochemical process and so on.
