ABSTRACT:
An alkaline nickel-cadmium storage battery in which the active material with which the negative electrode is filled with, or the electrolyte in the storage battery, contains polyvinylpyrrolidone as an expander. Polyvinylpyrrolidone compounds having a mean molecular weight of 5,000 to 35,000 g/mol have proved particularly advantageous.
