Abstract :
For pt.I see ibid., p.124-131 (1988). Results of accelerated tests of the effect of positive polarization on grid growth at 160°F are presented, along with new data at 147°F and 120°F. It is shown that minimal growth occurs at 40 mV, rather than at the 50-100 mV values previously considered optimal. Growth at 20 mV and below is well behaved and not catastrophically rapid, as previously believed. At >100 mV, a value often used in float service, growth is greatly accelerated and is significantly greater than 20 mV and below. Capacity falloff with aging is primarily a function of grid growth, without regard to the polarization which produced it
