Wound thermal batteries and methods of manufacturing the same

A method of manufacturing a thermal spiral wound battery comprising:

• preparing a first slurry comprising an anode material, a first polymeric binder, and a first volatile solvent;
• depositing the anode material from the first slurry onto a first conductive substrate to form a first conductive layer;
• preparing a second slurry comprising a cathode material, a second polymeric binder, and a second volatile solvent;
• depositing the cathode material from the second slurry onto a second conductive substrate to form a second conductive layer;
• preparing a third slurry comprising an electrolyte/separator material, a third polymeric binder, and a third volatile solvent;
• depositing the electrolyte/separator material from the third slurry onto a third conductive substrate to form a separator layer;
• stacking the first conductive layer, the separator layer, and the second conductive layer such that the separator layer separates the first conductive layer and the second conductive layer;
• and
• winding the first conductive layer, the separator layer, and the second conductive layer together into a spiral wound configuration.
