City Labs, Inc. is a Florida-based corporation specializing in designing, developing, and manufacturing ultra-low power, long-life tritium-powered nuclear batteries. These batteries are primarily used to power microelectronics, sensors, and other devices used in the aerospace, defense, medical, and industrial sectors. City Labs operates a regulatory-licensed R&D/manufacturing facility located in Miami, Florida.

History

City Labs, Inc. was founded in April 2005 by Peter Cabauy and Denset Serralta.[1] The company initially assembled a team of scientists and engineers from national laboratories and universities, including Larry C. Olsen, to create the first commercially available tritium battery.[2]

City Labs developed its first NanoTritium™ battery prototypes in December 2008 and provided them to Lockheed Martin for testing. These prototypes were subjected to extreme temperature testing from -55°C to +150°C and demonstrated continuous operation without performance degradation.[3]

In October 2010, City Labs received the industry’s first General License for the distribution of its tritium betavoltaic batteries. This license lets end-users purchase and receive the batteries without needing prior radiation licenses or radiation training.[4]

Products and Technology

City Labs is known for its NanoTritium™ battery technology, which employs tritium, a naturally occurring isotope of hydrogen and byproduct of nuclear power plants, to create long-life batteries. These batteries are designed to provide low-level continuous power for over 20 years, making them suitable for applications in extreme environments and long-term use cases such as aerospace and medical devices.[5]

NanoTritium™ Battery Technology

NanoTritium™ batteries are resistant to a wide range of physical stressors and environmental conditions due to the robustness of the tritium decay process. Independent testing confirmed the battery's resistance to extreme temperature variance and its capability to endure extreme vibration and altitude changes.[6]

The batteries convert tritium’s decay energy into electrical power. As tritium's half-life is 12.32 years, these batteries are capable of providing predictable and steady power output over their lifespan, which can last several decades.[7] This makes NanoTritium™ batteries ideal for applications that require long-term power solutions without the need for frequent replacements.

Applications

NanoTritium™ batteries are used in many fields, including:

  • Aerospace and defense: Powering sensors, communication devices, and other critical systems in extreme environments[8]
  • Medical: Supporting devices like pacemakers and other medical implants that require reliable, long-term power[9]
  • Industrial: Providing power for sensors and monitoring equipment in remote or harsh conditions[10]
  • COMSEC devices: Maintaining encryption keys and secure communication systems with long-lasting power sources[11]
  • Satellite propulsion: Enabling continuous power for advanced satellite propulsion systems[12]
  • Autonomous image sensors: Powering autonomous sensors for space missions and other remote applications[13]

City Labs has collaborated with NASA on various projects aimed at developing NanoTritium™ power sources for future space applications. These power sources are relevant due to their long-lasting energy capabilities and robustness in withstanding the harsh conditions of space, including exposure to high radiation levels, extreme temperature fluctuations, and intense vibrations during rocket launches.[14]

These projects include the development of autonomous tritium micropowered sensors designed for deployment across the Moon's south pole. These sensors are intended to detect water and other volatiles in permanently shadowed craters that may serve as valuable resources for future human settlements.[15]

Awards

City Labs has been awarded several Small Business Innovation Research (SBIR) grants from various U.S. government agencies, including the U.S. Air Force, U.S. Space Force, and National Institutes of Health. These grants have supported the development of City Labs' betavoltaic batteries for applications ranging from medical implants, cryptographic power solutions, and aerospace technologies.[16]
