Lead acid batteries are among the batteries that are usually used for high power supply. This battery is mainly used in cars. Lead acid batteries have large dimensions and relatively high weight. This type of battery is also used in emergency power sources due to its ability to store high energy.<\/span><\/p>\n

The lead-acid battery, historically, is the oldest rechargeable battery and has an acceptable current for its weight and volume. Lead-acid batteries are divided into two main groups: wet lead acid and dry lead acid.<\/span><\/p>\n

Lead acid battery, wet electrolyte<\/span> <\/span><\/h1>\n

This type of battery was more common in the past and used acid water solution. Its main advantage is its reasonable price, but the defects cannot be ignored. The main disadvantage of this type of battery is the need for constant maintenance and the dangers of using acid. In addition, the emission of toxic gases during charging, exposes humans to respiratory diseases, for this reason, it requires a space with proper ventilation.<\/span><\/p>\n

In batteries, there are metal plates known as anode and cathode. The electric charge of the anode plate is positive and the cathode is negative. When the battery is being discharged, the electrons move from the cathode to the anode. In other words, they are removed from the cathode and go to the anode. In the case of lead-acid batteries, it should be said that lead oxide is used as a chemical substance. Most of the lead used in lead-acid batteries is on the negative side, but since lead is not malleable, alloys are also added to it.<\/span><\/p>\n

To create a charge transfer path from the cathode to the anode, the plates must be placed in a liquid called an electrolyte. In the case of lead-acid batteries, this electrolyte is actually a solution of sulfuric acid and water. In this type of battery, there is also a part as a separator. These separators have the role of isolating the positive and negative poles. There are different types of these separators.<\/span><\/p>\n

The types of lead-acid battery separators from lowest to highest electrical conductivity are:<\/span><\/h2>\n
    \n
  1. PVC separators:<\/span><\/li>\n<\/ol>\n

    \u00a0\u00a0\u00a0 This separator is made of lead and antimony alloys, which is among the weakest in terms of electrical conductivity.<\/span><\/p>\n

      \n
    1. Cellulose separators<\/span><\/li>\n<\/ol>\n

      These separators have relative strength for electrical conductivity.<\/span><\/p>\n

        \n
      1. Polyethylene separators<\/span><\/li>\n<\/ol>\n

        These separators have good mechanical strength.<\/span><\/p>\n

        And they lead well.<\/span><\/p>\n

          \n
        1. AGM separators are almost among the best separators.<\/span><\/li>\n<\/ol>\n

          These separators have a very high effect on the return of oxygen released in reactions to the chemical environment of the battery.<\/span><\/p>\n

            \n
          1. GEL separator<\/span><\/li>\n<\/ol>\n

            This separator is also like AGM, except that the electrolyte does not flow as a liquid<\/span><\/p>\n

            And it is in the form of gel and paste.<\/span><\/p>\n

            Sealed acid battery<\/span><\/h2>\n

            A type of acid batteries that have a special valve, because these batteries do not need to add water or acid and controlling them due to the internal recombination of gases. The valves of these batteries should not be opened in any way, because they severely cause the loss of the internal gases of the battery, and as a result, the lifespan of the battery will be reduced.<\/span><\/p>\n

            The applications of sealed acid batteries are:<\/span><\/p>\n
