Lead acid batteries are the most used rechargeable batteries in the world. Lead chemistries are used in combustion engines as an SLI battery, emergency lighting systems, power tools, and also in low-speed electric vehicles, such as scooters, forklifts, and golf carts. Lead acid batteries use lead and sulfuric acid as their main components.
Sulfuric acid H2SO4 is used to activate the lead elements of the lead battery to get the power effect. Acid is prepared by mixing with water. Correct acid concentration levels are critical to ensure the successful power activation effect of the lead-acid battery.
Both electrodes are immersed in an electrolytic solution of sulfuric acid and water. Vaisala offers measurement solutions to monitor sulphuric acid concentration and optimize curing chambers for battery plates. Sulfuric acid H2SO4 is used to activate the lead elements of the lead battery to get the power effect.
Utilize chambers to the full and decrease downtime in production. With the help of Vaisala's measurement, get the correct sulphuric acid concentration during lead-acid battery manufacturing, and optimize curing chambers for lead-acid battery manufacturing.
The influence of sulfuric acid concentration on negative plate performance has been studied on 12 V/32 Ah lead-acid batteries with three negative and four positive plates per cell, i.e. the negative active material limits battery capacity.
In the H-region of acid concentrations, the utilization of NAM and PAM decreases, while that of H 2 SO 4 increases with decrease of acid concentration from 1.27 to 1.18 sp.gr. Batteries with electrolytes within this region of acid concentrations have lower initial capacity ( Co ), longer cycle life and higher charge efficiency.
