Abstract: The present invention provides a thin, bendable, printed, layered primary battery structure without a battery separator. The battery includes a first layer including a printed positive electrode. A second layer includes a negative electrode material which may be a printed negative electrode or a metal foil negative electrode. An adhesive, UV-curable intermediate layer is adhered to the first layer on a first side of the intermediate layer and is adhered to the second layer on a second side of the intermediate layer. The intermediate layer includes a water-soluble electroactive material and a water-soluble viscosity-regulating polymer in an amount sufficient to render the intermediate layer adhesive. The intermediate layer also includes a water-insoluble polymer matrix having sufficient rigidity to prevent contact of the first layer and the second layer. A flexible package encases the first, second, and intermediate layers.

Abstract: A UV-curable and printable combination separator and solid electrolyte precursor material for lithium ion batteries is provided. The precursor material includes a lithium salt dissolved in one or more organic solvents. A UV-curable monomer is included in an amount from approximately 4 weight percent to approximately 10 weight percent along with a UV-initiator. One or more host ion conductive polymers are provided in an amount less than approximately 5 weight percent of the precursor material and a ceramic powder. The precursor material, when cured, has sufficient mechanical rigidity to act as a separator preventing electrical shorting between a lithium ion battery cathode and a lithium ion battery anode. It also has sufficient electrical conductivity to function as an electrolyte for a lithium ion battery. A method for making a lithium ion battery is also provided where printing allows the formation of batteries with complex shapes.
