A Storage Battery is a device that converts chemical energy directly into electrical energy. It is a rechargeable battery that is recharged by a reversible chemical reaction. It is usually a lead-acid battery, which is one of the batteries and belongs to the battery. Working principle of 12V Storage Battery: When charging, the external active energy is used to regenerate the internal active material, and the electric energy is stored as chemical energy. When discharging, the chemical energy is converted into electric energy output again.
It uses a lead substrate grid filled with sponge lead as a negative electrode, a lead substrate grid filled with lead dioxide as a positive electrode, and a dilute sulfuric acid having a density of 1.26--1.33 g/mlg/ml as an electrolyte. When the battery is discharged, the metal lead is the negative electrode, and an oxidation reaction occurs to form lead sulfate; the lead dioxide is a positive electrode, and a reduction reaction occurs to form lead sulfate. When the battery is charged by direct current, the two electrodes generate elemental lead and lead dioxide, respectively. After removing the power supply, it returns to the state before discharge to form a chemical battery. The lead storage battery can be repeatedly charged and discharged. Its cell voltage is 2v. The battery is a battery pack composed of one or more monomers. The battery is referred to as the battery. The most common ones are 6v, 12v batteries, and others are 2v, 4v, 8v, 24V Storage Battery. For example, a battery used in a car (commonly known as a battery) is a battery pack in which six lead batteries are connected in series to form 12v.
