Radioactive batteries are certainly possible (and some exist). Achieving power levels and safety requirements for everyday use is the difficulty.
I realized some years ago it would be possible to make rechargable hafnium batteries. They would be awesome -- but you have to figure out a highly effcient means of converting gamma rays into electricity.

Carbon 14 is both radioactive and a semiconductor, meaning more of the beta particles are changed into electricity.
