Abstract
A method for making a cathode comprises introduction of polyethylene oxide into a suitable solvent prior to introduction of a compatible cathodic material and an electroconductive agent. The mixture of components forms a cathode paste which is used to form a cathode which can be employed in an electrolytic cell, e.g., a solid battery.
Claims14
A method for making a cathode comprising:
- (a) providing a cathode premix comprising 10 to 50 weight percent of solvent and 5 to 30 weight percent of a prepolymeric material;
- (b) introducing up to 20 weight percent of polyethylene oxide into the premix to form a mixture;
- (c) introducing 35 to 65 weight percent of a compatible cathodic material and 1 to 20 weight percent electroconductive material into said mixture so as to provide a cathode paste;
- and
- (d) producing a cathode from said cathode paste;
- wherein all weight percents are based on the total weight of said cathode paste.
