Abstract:

Five experimental separator membranes have been cycle life tested in 25 a.h. cells at 40 depth-of-discharge. The best of these, a divinylbenzene, methacrylic acid-grafted low density polyethylene yielded 162 cycles. Cells containing mixtures of KOH and NaOH were cycle life tested at 60 depth-of-discharge. All the mixtures, as well as 45 NaOH, resulted in shorter cycle life than KOH itself. Cells containing 1, 2, 3, and 4 layers of Dynel next to the positive plate were activated with 45 and 50 KOH and cycle life tested at 60 depth-of-discharge. One layer of Dynel in combination with 4 layers of FSC is adequate and 50 KOH yields somewhat better life than 45 KOH. A design change involving more and thinner plates is being incorporated into test cells. The Quality Assurance program is complete and results are reported.
