Abstract: The present invention is directed to a starch-based battery system. The starch-based battery system uses a rheological and replaceable starch gluten electrolyte that generates colloidal starch gel adhesive contacted with and/or attached on electrodes to generate current for powering electronic devices. The starch-based battery system that includes control circuit and standard cap module replaces a conventional dry cell battery or is integrated with electronic devices to power, for example, flash-light, lighting ornaments or magnetic actuated motion products and toys. In other embodiments of the invention, the starch-based battery system is integrated into a device for attracting aquatic life forms in an aquatic environment, wherein the starch-based battery powers a light source and/or sound source and also the starch gluten electrolyte acts as bait for attracting aquatic life forms within the aquatic environment.
