DESIGN, FABRICATION AND TESTING OF VENTED, RECHARGEABLE SILVER-CADMIUM CELLS

The objectives of this program were to design, build, and test vented silver-cadmium cells, in four sizes with a common base area. Four cell types were constructed with the following rated capacities at the five-hour rate: Type 2 - 7 ampere-hours; Type 3 - 15 ampere-hours; Type 4 - 22 ampere hours; Type 5 - 31 ampere hours. The report gives the capacities obtained from engineering evaluation tests for capacity, room and high temperature storage, cold temperature, and data on cycle life. The test results indicate that the silver-cadmium cells constructed from pasted positive and pressed negative electrodes should meet the functional test requirements.
