Summary form only given as follows. Six 48-Ah individual pressure vessel (IPV) Ni/H/sub 2/ cells containing 26 and 31% KOH electrolytes have been on a low earth orbit (LEO) cycle life test. Three cells containing 31% KOH have failed after an average of 6400 cycles while the other three with 26% KOH have cycled for an average of 19500 cycles. The authors have carried out post-cycle characterization...
Eagle-Picher Ind. Inc. (EPI) began production of Ni-H/sub 2/ and Ni-Cd cells for Hughes Aircraft Co. (HAC) and other users in 1988. The cells use electrochemically-deposited (ED) positive plates that are produced through a process that is unique to EPI and HAC. Since that time EPI has delivered over 1,200 Ni-H/sub 2/ cells providing battery systems for 23 active satellites. EPI has produced over 1,400...
