Lead-coated glass fibre mesh grids for lead–acid batteries
- 92 Downloads
A lightweight lead-coated glass fibre mesh grid was tested for use in valve-regulated lead–acid (VRLA) batteries. Plates made with these new grids show a higher material utilization over a wide range of discharge rates (i.e., 20–200 mA g−1) and temperature (i.e., −15–25 °C) compared with conventional gravity-caste plates. The results also suggest that the lead-coated glass fibre grid can replace the conventional gravity-cast grid without causing any deleterious effects so far as the cycle life is concerned.
