Storage Battery is the chemical energy directly transfer into electricity device, according to the rechargeable battery recharging design, achieved by reversible chemical reaction. It usually refers to the lead-acid battery, it is one of a battery pack, which belongs to the two battery. Its working principle is when charging, the external power for the regeneration of internal active substances, the energy stored as chemical energy, need to discharge again converted to output energy and chemical energy, such as commonly used in mobile phone battery.
When the battery is charged with direct current, the lead and two lead oxide are formed at the poles. After the power is removed, the battery is restored to the state before discharge, and a chemical battery is formed. For example, a battery used in automobiles is a Battery Cell in which 6 lead batteries are connected in series into 12 V.
