On a photo: nickel-hydrogen storage battery 18HB-80:
Purpose and design
The battery is used for a direct conversion of the electric energy into the chemical energy of nickel hydroxide and hydrogen reaction, for conservation of the energy in this form for a definite time and its reverse conversion into the electric energy. Nickel-hydrogen storage battery is contained in a pressure vessel with a common gas collector.
Field of application
The batteries are intended for applications in space vehicles, operating on the geostationary and low near-earth orbits.
Basic advantages
Compactness. High efficiency, silent operation, absence of hazardous emissions. Ability to work in any space position and at great overloads (10 g - axial, 100 g- impact).
Development prospects
The battery of 2,5-200 Ah capacity and a number of storage cells reaching 75 pcs. can be manufactured using the complete parts of NHSB.
