MicroLink and City Labs anticipate that the proposed work will result in the creation of a betavoltaic battery with a volumetric power density of 200 microwatts/cm3, a lifetime in excess of 20 years, an energy density of 20 times that of lithium batteries (integrated over 20 years of continuous power) and a cost reduction of a factor of 10 (from $1000/microwatt to $100/microwatt). This combination of factors will allow tritium betavoltaics to be introduced to a mainstream market in a number of potential NASA applications, including high value deep space missions, independent power sources for spacecraft electronics and backup communications systems.
Potential non-NASA applications include: battery back-up power for FPGA encryption keys used in many defense and security applications, domestic anti-tamper for defense applications, nuclear storage/ device monitoring for defense applications, satellite power supplies, including cubesats, SRAM (static random access memory) volatile memory, sensors, and medical bionics/ implants. In the government sector, customers include the US Air Force, US Navy, Special Forces, CIA, NSA, and NRO. In the commercial sector, potential customers include commercial satellite manufacturers, such as Lockheed Martin, Boeing, and Space Systems Loral, medical device makers, semiconductor device makers, such as Intel, and AMD, and sensor makers. It should be noted that City Labs has sold prototype and commercial batteries into select high value markets with premium customers such as Lockheed Martin, NASA?s Jet Propulsion Laboratory, and Lawrence Livermore National Laboratory.
