Sample text

Cycling was terminated because of low end-of-discharge voltage after about 1200 cycles at 65% DOD. Testing was conducted at 20°C. Following testing at NASA's Marshall Space Flight Center (MSFC), two cells were shipped to Aerospace for DPA. At Aerospace, a 72 h capacity retention test was performed to verify that the poor performance was not caused by an internal short circuit. 0 V cutoff was 85%. This value is considered to be very good and not indicative of a low-level internal short circuit. 7).

The difference between Type 1 and 2 was related to whether 6% or 10% of the cell's fully charged capacity was discharged prior to entering into the cycling regime. The wide range of corrosion rates as inferred from the rate of pressure rise at the end of the charge portion of the cycle during the test should be noted. 3 shows the results of pressure rise data collected from databases sponsored by NASA and the Air Force. In this bar graph, the results are separated into cells that were cycled to 35% DOD and cells that were cycled to 60% DOD.

A significant concentration gradient from one end of the stack to the other is typical of cells using the recirculating stacking arrangement. In cells having this electrode arrangement, the oxygen from the positive electrode of one plate pair combines with hydrogen on the negative electrode of the next plate pair. For this reason, there is a gradual movement of water from one end of the cell to the other. As this happens, there is a gradual decrease in the electrolyte concentration in the direction of the water movement.
