What kind of electrolyte should be paid attention to when configuring lead-acid battery electrolyte?

The preparation method of the lead-acid battery electrolyte: the electrolyte of the lead-acid battery is a dilute sulfuric acid solution prepared by adding water and concentrated sulfuric acid. The quality of the electrolyte has a great influence on the service life and capacity of the battery, so the correct preparation method must be mastered. The electrolyte of the lead-acid battery must use the special sulfuric acid of the battery, which should be clear, transparent, colorless, and odorless; the content of iron, arsenic, manganese, chlorine, nitride, etc. should not exceed the standard. Pure water, distilled water or purified drinking water is used as the water for preparing electrolyte. Different types of batteries have different requirements for electrolyte concentration. To consider from the aspects of battery power supply characteristics, battery structure, and working environment, the following situations must be considered: 1. Lead-acid batteries for mobile work Adapt to field work, prevent freezing, have some restrictions on volume and quality, and do not allow a large amount of electrolyte. To ensure sufficient capacity, use a higher concentration of electrolyte. The volume and quality of the fixed working battery are not too limited. Generally used indoors. 2. Within a certain range, the greater the electrolyte concentration, the greater the concentration of sulfuric acid in the active material of the electrode plate. The active material utilization rate is high, and the capacity will be increased. However, if the electrolyte concentration is too high, the resistance of the solution is increased, the viscosity is also increased, the penetration rate is low, and the self-discharge is accelerated, and the battery capacity decreases instead. If the electrolyte concentration is too high, the corrosion of the separator will be accelerated accordingly, which will shorten the service life of the battery. 3. When choosing the electrolyte concentration, the working environment temperature of the battery should also be considered. Working in cold temperatures, the electrolyte concentration should be higher, and in hot temperatures, the electrolyte concentration can be lower.
