Detailed explanation of the use of lithium battery technology in the field of energy storage

The use scenarios of lithium batteries on the power side, user side, and grid side of energy storage are as follows: the use of energy storage on the power generation side includes optical storage power stations, wind storage power stations, and AGC frequency modulation power stations; the focus on user side energy storage includes optical storage charging stations , Home energy storage, backup power supply, etc.; grid energy storage uses substation energy storage, virtual power plant, peak shaving/frequency modulation and other scenarios. At present, there are two mainstream energy storage lithium batteries, ternary lithium and lithium iron phosphate, and their power density is much higher than that of lead-carbon batteries. Relatively speaking, ternary lithium is higher than lithium iron phosphate. With the development of electromagnetic emission technology, energy storage has become an indispensable part of it. Decompose the requirements of the basic energy storage unit, take the power and energy requirements of the electrical system as the traction, and aim at the optimal fit of the volume and weight of the energy storage system, and fully compare the existing battery parameter indicators, from safety and power density The four aspects of energy density and cycle life are considered, and the basic energy storage unit type is determined to be a lithium battery. Energy storage is a new market with broad development prospects for lithium batteries. It is known as the new blue ocean for lithium battery use. Some leading lithium battery companies have set their sights on this market. The author believes that within 5 years lithium battery manufacturers should be able to deal with price and technical issues, and realize the large-scale commercial use of lithium batteries in the field of grid energy storage.
