<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing aqueous electrode paste being paste for manufacturing an electrode for a battery, containing a lithium transition metal composite oxide as an active material and an aqueous solvent and hardly causing variation of flowability after preparing it. <P>SOLUTION: This manufacturing method of aqueous electrode paste includes a process for preparing a primary mixture by making the aqueous solvent of predetermined pH, a lithium salt for shifting the pH of the aqueous solvent to the alkaline side, and a polymer dissolving in the aqueous solvent coexist with one another. The manufacturing method includes a step for adding particles of a lithium transition metal composite oxide to the mixture after viscosity of the primary mixture is stabilized. By the manufacturing method, the aqueous electrode paste hardly causing variation of flowability (for instance, degradation of viscosity) after preparing it can be provided. <P>COPYRIGHT: (C)2007,JPO&INPIT |
