  • Lithium battery energy storage power supply principle

    Lithium battery energy storage power supply principle

    A lithium-ion battery or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. Electricity is the flow of electrons. When electrons move, they do work, for example, by running a motor. There are many different varieties, which are usually categorized by the materials used in the cathode. This technology stores energy through a reversible chemical reaction, allowing it to be repeatedly charged and discharged. Lithium-ion batteries are the dominant electrochemical grid energy storage technology because of their extensive development history in consumer products and electric vehicles. Characteristics such as high energy density, high power, high efficiency, and low self-discharge have made them attractive.
