Comsat Develops Lightweight Satellite Battery

A new nickel-hydrogen battery technology that will double the operational life of new low earth orbit (LEO) satellite systems has been developed by Comsat Laboratories, a unit of Washington, D.C.-based Comsat Corp., and licensed to Eagle- Picher Industries, Inc.

The new Common Pressure Vessel (CPV) will result in significant size and weight savings over the existing Individual Pressure Vessel (IPV), pioneered by Comsat Labs and also previously licensed to Eagle- Picher.

The CPV will allow a communication satellites in LEO to carry an additional payload or extend its operational life. Enhanced thermal performance will allow greater depth of discharge and a lighter battery, increasing the satellite's useful life by more than 100 percent.

Eagle-Picher, of Cincinatti, currently maintains 90 percent of the world's nickel-hydrogen battery market.
