18650 4600MAH 3.7V Rechargeable Lithium-ion Battery

A rechargeable battery is a type of electrical battery that is comprised of one or more electrochemical cells. It is known as a secondary cell because its electrochemical reactions are electrically reversible. In other words, after the stored charge has been drained, the battery’s chemical reactions can occur again, in reverse, to store a new charge. The U.S. demand for rechargeable batteries is growing twice as fast as the demand for non-rechargeable batteries, in part because rechargeable batteries have lower environmental impact and total cost of use than do disposable batteries.

Grid energy storage applications use rechargeable batteries for load-leveling. Load-leveling involves storing electric energy for use during peak load period. By charging batteries during periods of low electrical demand for use during periods of high demand, load-leveling helps eliminate the need for expensive peaking power plants and helps reduce the cost of generators over more hours of operation.

Rechargeable Battery Construction

As with all batteries, rechargeable batteries consist of an anode, a cathode, and an electrolyte. During charging, the anode material is oxidized, producing electrons, and the cathode is reduced, consuming electrons
