Scientific paper

The Dependent Pressure Vessel (DPV) Nickel-Hydrogen (NiH2) design is being developed by Eagle-Picher Industries, Inc. (EPI) as an advanced battery for military and commercial, aerospace and terrestrial applications. The DPV cell design offers high specific energy, energy density and reduced cost, while retaining the established Individual Pressure Vessel (IPV) technology flight heritage and database. This advanced DPV design also offers a more efficient mechanical, electrical and thermal cell and battery configuration and a reduced parts count. The DPV battery design promotes compact, minimum volume packaging and weight efficiency, and delivers significant cost and weight savings while providing minimal design risks. This presentation will discuss new DPV design concepts and production features and present test data from existing development cells. The DPV combines the unique features and significant advantages of NiH2 electrochemistry with the simplicity and extensive design heritage of the NiCd battery system to create a power source ideal for military and commercial terrestrial projects as well as traditional aerospace applications.
