ABSTRACT:
A method for forming a slurry cell electrode structure which serves as a component of a planar battery. The slurry electrode structure is formed in situ as a particulate dispersion of active material in aqueous electrolyte. The method utilizes a slurry precursor prepared by predepositing a liquid carried dispersion of the particulate active material over the surface of a select component, such as a separator, current collector, or intercell connector of the cell. This deposition is dried and prepared as a subassembly which is appropriately inserted within the multicell pile structure as a step in the manufacture of a multicell battery. By wetting the subassembly with a wash coat of aqueous electrolyte, in situ slurry formation is provided.
