Title: Water based biological and photochemical batteries

Abstract: The designs of prototype batteries are described based on some biological Fenton reactions and the photo-excitation of singlet oxygen. The biological battery consists of hydrogen peroxide (or an acid) and ferrous gluconate complexed with a second ligand. Salts such as sodium chloride or ammonium chloride are used as the electrolyte. The photochemical battery uses an aqueous paste of ferrous gluconate with an additional ligand and is irradiated by light. The power of the battery is higher by adding small amount of titanium oxide to ferrous gluconate. The power of these batteries can be increased by using higher concentration of the chemicals or connecting multiple batteries in sequence and/or in parallel. Replacing ferrous ion with cupric ions increases the current of the battery by about 20 times.
