What is the electrolyte and what is the composition of the battery electrolyte

Car battery can be said to be an indispensable component, not only to supply power to electrical equipment, but also to protect the role of automotive electrical appliances. But when asked what the electrolyte in the battery is, many friends said that they were not very clear. So, to answer your doubts, let’s talk about the composition of battery electrolyte.

The electrolyte is actually a medium used by the battery (with certain corrosiveness), which provides the corresponding ions for the normal operation of the car battery and ensures that the chemical reaction of the battery is reversible. As for the electrolyte composition of lead-acid batteries, it is made up of 80% sulfuric acid and distilled water in a certain proportion, which belongs to the electrodeless water electrolyte, and its density is generally in the range of 1.24-1.30g/cm.

It is worth mentioning that when the battery lacks electrolyte, we must replenish it in time. Otherwise, it will not only lead to a decrease in battery capacity, but also cause deformation of the internal structure. Therefore, in order to avoid the occurrence of these situations, you must not ignore the electrolyte in your daily inspections.
