Radioelectric battery

In 1951, the first battery to convert radioactive energy to electrical was announced. Invented by Philip Edwin Ohmart of Cincinnati, Ohio, it consisted of two electrochemically dissimilar electrodes separated by a filling gas that was ionized by exposure to the nuclear energy to produce electrical current. Ohmart obtained an emf efficiency of .01% on a cell using magnesium dioxide and lead-dioxide with argon as the gas and Ag110 as the radioactive source.
