Technical principles and uses of energy storage lithium-ion batteries

Technical principles of energy storage lithium-ion batteries Energy storage technology refers to the storage of energy-storage lithium-ion batteries through physical or chemical methods, and releases when needed. The storage of energy storage lithium-ion battery tools can be classified into three categories, mechanical energy storage, electromagnetic energy storage and electrochemical energy storage. Mechanical energy storage lithium ion batteries can be further divided into pumped water energy storage lithium ion batteries, compressed air energy storage lithium ion batteries, and flywheel energy storage lithium ion batteries. Electromagnetic energy storage mainly includes superconducting magnetic energy storage and supercapacitor energy storage. The capacity range of the energy storage system is relatively wide, from tens of kilowatts to 100 megawatts; the discharge time span is large, from milliseconds to hours; the scope of application is wide, running through the entire power generation, transmission, distribution, and electrical system; large-scale power The research and application of energy storage technology has just started. It is a brand-new subject and a hot area of u200bu200bresearch at home and abroad. Lithium-ion battery market occupies an increasingly important position. Uses of energy storage lithium-ion batteries Energy storage lithium-ion batteries belong to large-scale, centralized energy storage. The technology is quite mature and can be used for energy management and peak shaving of the power grid. The efficiency of energy storage lithium-ion batteries is generally about 65% 75%, the highest Up to 80% 85%;: fast load response speed (10% load change takes 10 seconds), about 5 minutes from full stop to full load, and about 1 minute from full stop to full load; energy storage lithium-ion battery has daily The adjustment capability is suitable for cooperating with nuclear power plants, large-scale wind power generation, and ultra-large-scale solar photovoltaic power generation. In order to promote the optimization and upgrading of the energy industry and achieve clean and low-carbon development, in recent years, my country has vigorously developed clean energy. Wind power and photovoltaics have achieved leapfrog development, and the proportion of new energy installed capacity has increased.
