Battery BB-674( )/U Nickel-Zinc Secondary.
Abstract
The design, development and test of the BB-674( )/U battery is described in detail. The BB-674( )/U is a 4 cell nickel-zinc secondary battery. It is rated at 6.5 volts and 35 ampere-hours capacity. The design has 40 A-H of positive capacity in standard sintered nickel plates and teflonated ZnO negative plates. The zinc plates have almost 4 times the required coulombic capacity and are equal in area to the positive plates but are edge densified to retard shape change. The searator consists of 2 layers of fibrous visking plus Pellon bags on both positive and negative electrodes. The BB-674( )/U successfully completed its qualification test program for advanced development models of this battery. The qualification test results are presented for shock, vibration, low temperature charge retention, cycle life + high rate tests. As a result of this program, the BB-674( )/U design was considered to have passed qualification testing. (Author)
