Case Study – AA Battery <strong>Technologies</strong><br />
Conceptual Betavoltaic Batteries<br />
Semiconductor<br />
Radioisotope<br />
• May lead to creating new power sources having several<br />
advantages over currently existing counterparts<br />
• Improved energy density<br />
• Efficiency<br />
• Much longer product lifetimes<br />
• Betavoltaics are direct nuclear to electrical energy conversion<br />
devices<br />
• Concept was proven >50 years ago, but device<br />
per<strong>for</strong>mance quickly degraded due to radiation damage<br />
to silicon<br />
• New material, icosahedral boron arsenide (IBA), being<br />
studied<br />
• Alternating layers of the radioisotope beta source <strong>and</strong><br />
semiconductor materials would be present within the<br />
battery shell.<br />
