This invention relates to methods to produce solid electroyte composites and solid electrode composites employed extensively to fabricate various solid electrochemical devices such as batteries, capacitors, sensors, display devices, recording devices, etc., and also to offer methods to produce solid electrolyte composites of high mechanical strength and large area electrode composites wherein fine powders of said solid electrolyte are uniformly dispersed. n The methods to produce said solid electrolyte composites and solid electrode composites of the invention include a process to produce slurry by dispersing said solid electrolyte powders in a solvent in which plastic resin in dissolved, a process to remove said solvent from said slurry, and a process to add to the solvent one of the compounds selected from (a) to (e): (a) is a catonic surfactant having ethylene-oxide chains and/or propylene-oxide chains; (b) is a cationic surfactant having ethylene-oxide chains and butyleneoxide chains; (c) is a polyether compound produced by adding ethylene-oxide and/or propylene-oxide to a polyamine compound; (d) is a polyether compound produced by adding both ethylene-oxide and butylene-oxide chains to a polyamine compound; and (e) is an amide compound which is a dehydro-condensation product of polyalkyleneimine and fatty acid. |
