资料摘要:
12 V/25 AH gelled-electrolyte valve-regulated lead-acid batteries have been assembled in-house
and their performance studied in relation to the absorptive glass-microfibre valve-regulated and floodedelectrolyte
counterparts at various discharge rates and temperatures between – 40°C and 40°C. Although the
performance of the gelled-electrolyte valve-regulated battery is similar to both the absorptive glass-microfibre
valve-regulated and flooded-electrolyte lead-acid batteries at temperatures above 0°C, it is superior to both
the flooded-electrolyte and absorptive glass-microfibre valve-regulated lead-acid batteries at temperatures
between 0°C and – 40°C. The latter characteristic is attractive for expanding the application regime of valveregulated
lead-acid batteries. The corrosion rate for the positive grids in the gelled-electrolyte is also lower
than both the flooded-electrolyte and absorptive glass-microfibre configurations.
