Abstract
An electrode assembly for use in a galvanic cell is provided. The galvanic cell may include a first electrode, a gel polymer adhesive electrolyte in contact with the first electrode, a polymer tri-phase electrolyte layer, a separator coupled between the gel polymer adhesive electrolyte and the polymer tri-phase electrolyte layer, and a second electrode in contact with the polymer tri-phase electrolyte. A method of making and using an electrode assembly for use in a galvanic cell is provided.
Claims19
An electrode assembly, comprising:
- a first electrode, the first electrode comprising an anode, the anode comprising an active material, a binder, and at least one conductive additive, wherein the active material is a metal hydride;
- a gel polymer adhesive electrolyte layer, in contact with the first electrode;
- a polytetrafluoroethylene latex layer;
