The electrolytic solution used in the lead-acid battery is a concentration of 37 to 42% sulfuric acid solution. The formulated general method is to dilute concentrated sulfuric acid with water, and the specific gravity of the electrolyte of the sulfuric acid solution is generally selected. The dry charge battery is generally used 1.24 to 1.28 g / cm3 sulfuric acid solution; the valve controlled battery is generally used with a sulfuric acid solution of 1.30 to 1.34 g / cm3; and the use environment is different, the corresponding electrolytic solution is different, and the general tropical region The required electrolyte specific gravity relative is 0.01 to 0.03 g / cm3 lower than the regular basis.The purity of the electrolyte has a great influence on the lead-acid battery, so the different categories of battery use, the sulfuric acid used is different, and the normal battery is not high. It is not high, and the battery is specially sulfuric acid; and the valve control type Sealed batteries must be used to analyze pure sulfuric acid.
Classified by electrolyte and charging maintenance:
1 Dry-discharge battery. The polar plate is in the dry assay discharge state, injecting the electrolyte and performing initial charging.
2 dry charge storage battery. The polar plate is in a state of drying and the injection of the electrolytic solution can be used for a short time; 3 with liquid storage battery. You can use:
4-free maintenance battery, normal use process does not need to maintain water;
5 less maintenance of the battery. Under normal operating conditions. Just add water for a long time;
6 wet load battery. Most of the electrohytic solution is poured after the charge is made. The structure of a common lead battery is mainly composed of a positive electrode plate group, a negative plate group, an electrolyte, and a container. Positive, the negative electrode plate is composed of a plate gate and an active substance. The plate is rushed to support the active material. The grille is generally used in lead bindies, and sometimes pure or lead calcium alloys.
