Background

Storage batteries (Storage batteries) are devices that convert chemical energy directly into electrical energy, are batteries designed to be rechargeable, and are recharged by reversible chemical reactions, and are commonly referred to as lead-acid batteries, which are one type of Battery and belong to secondary batteries. The working principle is as follows: when the battery is charged, the internal active substance is regenerated by using external electric energy, the electric energy is stored into chemical energy, and the chemical energy is converted into electric energy again to be output when the battery needs to be discharged, such as a mobile phone battery and the like which are commonly used in life. It uses lead-base grid (also called grid body) filled with spongy lead as negative electrode, lead-base grid filled with lead dioxide as positive electrode and dilute sulfuric acid whose density is 1.26-1.33 g/mlg/ml as electrolyte. When the battery discharges, the metal lead is a negative electrode and generates oxidation reaction to generate lead sulfate; lead dioxide is the anode and undergoes a reduction reaction to produce lead sulfate. When the battery is charged by direct current, elemental lead and lead dioxide are respectively generated at two electrodes. After the power source is removed, it is restored to the state before discharge, and the chemical battery is formed. The lead accumulator can be charged and discharged repeatedly, its single voltage is 2V, the battery is a battery group formed by one or more single cells, it is called accumulator for short, most commonly 6V, other 2V, 4V, 8V and 24V accumulators. For example, the accumulator (commonly called battery) used in automobile is a 12V battery pack formed by connecting 6 lead accumulators in series.
