PURPOSE:To obtain a homogeneous composition material by adding a cationic surface active agent with the ethylene oxide chain and propylene oxide chain or a surface active agent with either one of the ethylene oxide chain or propylene oxide chain into slurry. CONSTITUTION:Thermoplastic resin is dissolved in a lipophillic solvent to obtain a solution, a cationic surface active agent with the EO chain and/or PO chain is added, electrode active material powder, solid electrolyte powder, conductive material powder as necessary, or a mixture mixed with electrode active material powder and solid electrolyte powder and conductive material powder as necessary at preset mixing ratios in advance are added, and it is crushed and mixed by a mixing crusher to obtain electrode slurry. This slurry thus obtained is molded as it is, or it is extended or coated and molded on a supporter such as a Teflon plate and a nylon mesh sheet, then the solvent is dispersed to obtain an electrode composition material. Electrode slurry stable for a long period is obtained, and a homogeneous electrode composition material can be obtained when this slurry is solidified. |
