Nickel-Hydrogen Batteries and Cells

EaglePicher Technologies has an extensive heritage with its Nickel-Hydrogen rechargeable cells and batteries in high-reliability space missions, including the Hubble Space Telescope and the International Space Station.

 ni-h2 space batteries

EaglePicher’s Nickel-Hydrogen technology includes:

  • State-of-the-art Nickel-Hydrogen manufacturing and testing facilities to ensure the highest standards of workmanship.
  • EPT has accumulated over 1.7 billion hours of Nickel-Hydrogen cell/battery performance in space with 100% mission success.
  • Proven safety and long-term reliability in critical applications such as scientific, commercial, and military missions.

Key Features
Our Nickel-Hydrogen technology includes the following features: 

Durability:

Nickel-Hydrogen cells are hermetically-sealed assemblies that offer the ability to withstand rigorous electrical requirements and temperature extremes seen in LEO/MEO/GEO applications. In addition to electrical testing, Nickel-Hydrogen batteries are subjected to a variety of nondestructive environmental tests to demonstrate the flightworthiness expected by customers. Extensive data has been collected from decades of in-flight operation and life-testing to demonstrate the robust performance of the Nickel-Hydrogen electrochemistry.

Electronics:

Nickel-hydrogen cells can be equipped with strain gages to monitor their state-of-charge, while batteries are capable of being outfitted with temperature control/monitoring components, bypass switches, and other specialized electronic devices to optimize performance.

 

Design Flexibility:

Cell diameters range from 2.5 to 5 inches, with nominal capacities ranging between 6Ah to 350Ah. A variety of multi-cell battery configurations exist and are tailored to the requirements of the spacecraft.
