Commercial nickel metal hydride (Ni-MH) batteries are under evaluation for potential application as a replacement for existing Ni-Cd and Pb-Acid batteries currently used by the USAF. Replacement of these batteries is desirable due to the high cost of maintenance and acquisition, the environmental hazards associated with worker exposure to hazardous materials, and the high cost of reclamation programs for these existing batteries. Both cylindrical and prismatic AB5 cells show promise for this application, but will require alloy and single cell development to reduce self-discharge and charge rates, and expand the temperature range to meet austere military environments. Tested AB2 cylindrical cell technology appear inadequate to meet military requirements although these cells show better charge capability at 71deg C than AB5 cylindrical or prismatic cells.
