Abstract

Available cylindrical and prismatic commercial Ni-MH batteries using AB₅ and AB₂ cathodes were evaluated for possible application to military aircraft batteries. Commercial AB₅ technology is further advanced than AB₂ technology and would require less alloy, electrolyte and single cell/battery development for near term (3-5 years) applications. Tested AB₂ technology appears inadequate to meet the near term military requirements and would require a major development in the alloy to overcome the irreversible capacity loss at temperatures above 49°C. In addition, significant advances in alloy, electrolyte and single cell/battery development would also be needed
