Abstract

A betavoltaic battery having layers of fissile radioisotopes 8, moderating material 7, beta-decaying radioisotopes 6, and semiconductor diode 4 & 5 adjacently stacked one above another, is proposed. Neutrons produced by the chain reaction in the fissile radioisotope 8 are slowed down by the moderating material 7 before penetrating into the layer of beta-decaying radioisotope 6 to cause fission. Beta particles produced from the fission of beta-decaying radioisotopes 6 create electron-hole pairs in the semiconductor diode 4 & 5. Electrons and holes accumulate at the cathode 9 and anode 2 respectively, producing an electromotive force. Because beta particles are produced from neutron-induced fission, instead of from beta decay, this betavoltaic battery is able to generate substantially more power than conventional betavoltaic batteries. Use Figure 1.

Bio

Bridging the gap between power output of fission reactors and small size of betavoltaic batteries.

This invention aims to bring together the benefits of the high power output (MegaWatts) of Nuclear Fission, and the small size & direct electrical output of betavoltaic batteries(millimetres).

Bringing Tony Stark[Iron Man]'s Arc Reactor Technology 1 step closer to reality.
