Challenges Ahead

· The power output of a Betavoltaic cell is not neccessarily uniform over its lifetime. The internal beta emitter decays, slowly decreasing in activity, and outputing less and less power.
· Betavoltaic batteries suffer internal damage from the electrons activity within.
· Betavoltaic batteries may be politically controversial, and therefore licensing may be an issue.
· May need to develop recovery procedures for spent Betavoltaic batteries.
