Detailed explanation of the application of lithium-ion battery energy storage technology

　　The importance of lithium-ion battery energy storage technology refers to the storage of electrical energy. The stored energy can be used as emergency energy, as well as to store energy during low grid loads and output energy during high grid loads for peak shaving and valley filling, reducing grid fluctuations.

　　Lithium ion batteries refer to batteries made of compounds containing lithium, which mainly rely on the movement of lithium ions between the positive and negative electrodes for operation. Lithium ion batteries can not only be used as power lithium-ion batteries but also as energy storage batteries. Due to the good safety of lithium-ion batteries, most energy storage stations choose ferrous phosphate lithium-ion batteries as energy storage batteries.

　　Lithium ion batteries are currently the most common energy storage technology on the market, widely used in various personal electronic products, mobile devices, and even in car batteries for electric vehicles. The lithium battery we usually refer to refers to lithium-ion batteries, which are generally divided into energy storage lithium batteries and power lithium batteries according to their uses. Energy storage lithium batteries are used in photovoltaics or UPS, with a relatively high internal resistance and slow charging and discharging speed, usually 0.5-1C. Power batteries are generally used in electric vehicles, with a low internal resistance and fast charging and discharging speed, usually reaching 3-5C, and are about 1.5 times more expensive than energy storage batteries.

　　Lithium ion batteries mainly rely on the movement of lithium ions between the positive and negative electrodes to operate. During its charging and discharging process, only lithium ions are present, without the presence of metallic lithium. Compared with other batteries, lithium batteries have the advantages of high energy density, longer cycle life, low self discharge rate, high energy conversion rate, and fast charging and discharging.
