Layered Structure Battery with Multi-Functional Electrolyte

A thin, bendable, printed, layered primary battery structure without a battery separator, comprising:

• a first layer including a printed positive electrode;
• a second layer including a negative electrode material, the second layer comprising a printed negative electrode material or a metal foil negative electrode material;
• an adhesive, UV-curable intermediate layer adhered to the first layer on a first side of the intermediate layer and adhered to the second layer on a second side of the intermediate layer the adhesive strength of the intermediate layer being at least approximately 6 kPa, the intermediate layer comprising:
• a water-soluble electroactive material;
• a water-soluble viscosity-regulating polymer in an amount sufficient to render the intermediate layer adhesive;
• a water-insoluble polymer matrix having sufficient rigidity to prevent contact of the first layer and the second layer;
• solid particles in a range of approximately 0.1% to 5%;
• and
• a flexible package encasing the first, second, and intermediate layers.
