Diehl & Eagle Picher GmbH (D&EP), a German-American joint venture, develop and produce thermal batteries for defence applications as well as customized battery packs for civil and military sectors. In addition D&EP successfully started to design and manufacture Lithium-Thionyl-Chloride reserve batteries for integration in proximity, time and multifunction fuzes for mortars, artillery and naval guns over 14 years ago.
This type of battery (Lithium-Thionyl-Chloride reserve battery) offers the distinguishing feature of a very high energy density and is non-active when delivered as the electrolyte is separated in an incorporated glass ampoule, which will only be shattered by acceleration during firing. Thus the battery will finally be activated and supplies energy for the fuze.
In summer 2016 D&EP produced their 500,000th Lithium reserve battery. This occasion was used to honor the very successful past years in this business segment.
Since production start in 2002 at D&EP in Röthenbach a. d. Pegnitz more than half a million reserve batteries have been manufactured for German and foreign customers.
Main customer has been and still is Junghans Microtec GmbH with their electronic fuzes L163/L166. Since then these Lithium reserve batteries have effectively been integrated in various fuzes such as 155 mm ammunition of tank howitzers 2000 (PzH2000) and 76 mm naval ammunition.
Due to the current order situation and with thanks to our main customer Junghans Microtec further incoming orders are to be expected for the years to come utilizing our production capabilities to capacity.
Regarding our 14 years of experience and our production know-how with respect to reserve-batteries D&EP has initiated development of “miniaturized“ Lithium-Thionyl-Chloride reserve batteries particularly for medium caliber electronic fuzes and has even reached production stage. This sector especially constitutes a potential growth market. Several interested customers have already placed their first design and serial orders.
