Army Eyes Next Generation Power Sources

Article excerpt

SAN DIEGO - The Army is investigating potential applications of high energy batteries and Stirling engines, among other technologies, said Mike Brundage, chief of power applications at the Army Research, Development and Engineering Command.

The Army is interested in lithium ion carbon monofluoride (Li/CFx) batteries to replace the BA-5590 standard military battery, he said at a conference hosted here by the National Defense Industrial Association.

The objective is to find Li/CFx batteries that have twice the run time at the same weight and volume, Brundage told attendees. More importantly, he said, the Li/CFx batteries should be half the size of their 5590 counterparts.

Currently, high-energy batteries provide twice the run time at the same weight as standard batteries. The BA-5590, which is made up of sulfur dioxide (Li/S02), weighs 2.16 pounds and emits 200 watt hours of energy. The Li/CFx batteries weigh 2.2 pounds and emit 400 watt hours of energy.

Brundage is also looking at hybrid batteries. …
