Flexible batteries

A method for manufacturing of a flexible battery, the method comprising:

• providing a first current collector, the first current collector comprising a first plate made from a first metal material;
• disposing an anode layer on the first current collector, the anode layer comprising an anode active mass, the anode active mass comprising substantially a silver;
• providing a second current collector, second current collector comprising a second plate made from a second metal material;
• disposing a cathode layer on the second current collector, the cathode layer comprising a cathode active mass, the cathode active mass comprising substantially a zinc hydroxide;
• disposing a separator layer between the anode layer and the cathode layer, the separator layer comprising a polymer material;
• joining, substantially parallel to each other, the first current collector, the anode layer, the separator layer, the cathode layer, and the second current collector to obtain a multi-layer structure;
• impregnating the separator layer with an electrolyte;
• and
• laminating the multi-layer structure with a polypropylene shell.
