The lithium ion battery energy storage technology and the analysis of market prospect

Source: 2020 - 04 - Capacity 10 hits: lithium ion battery energy storage technology and market prospect of 1. The application prospect because of the practical need of the power system in our country. A new generation of smart grid technology is developing rapidly. In 2007, the state grid corporation proposed 'key technology research and key techniques of energy storage energy conversion' framework. It promoted the rapid development of electric power energy storage system. At present, the government and the public are focusing on the aspects of technology and market. Grid system for distributed energy storage and smart grid development kw and mw of energy storage systems. Lithium ion battery energy storage system relative to the other battery energy storage system, has the very high energy density and environmental temperature to adapt to wide, charge and discharge characteristics of high efficiency, fast response speed, and dc bus power supply system in the distributed energy storage system has great advantages, the current small-scale pilot project has been used under the condition of lithium ion battery energy storage system, such as electric micro intelligent network application in yunnan institute of a 230 k W h lithium ion battery energy storage system and so on. With the rapid development of lithium ion battery, its security and cycles will further increase, prices will also be further reduced. Therefore, lithium ion battery energy storage system will be in the distributed energy storage system, wind system plays more and more important role in micro grid system. 2. Market forecast of large energy storage system is the future of new energy system and an important part of smart grid, and energy storage battery is the key of large energy storage systems. Lithium ion batteries with high energy density, charge and discharge efficiency, small self-discharge rate, output stability, and the advantages of green environmental protection, has become the mainstream of the energy storage battery solutions. 2011 global lithium ion battery market size of 1. 6693 trillion yen, growth in 108 than in 2010. 2%. Lithium-ion battery industry transfer to China the trend of more and more obvious, most of the lithium ion battery factory turning power/energy storage battery as a direction. According to statistics, by 2015, lithium-ion battery production capacity will exceed 5 billion Ah, the market size of about 15 billion dollars. The development of new energy sources such as wind power and solar energy, brought opportunities for battery energy storage. Guodian electric power development co. , LTD. Set up a special institution to research how to realize the wind smooth interpersonal network, the result is: 20% of the energy storage capacity matching wind capacity - 30%. By the end of 2010, the cumulative installed capacity of 41. 82. 7 billion W, with 8365 wind power industry in China's energy storage industry alone. 4 - 12548. Potential market of 1 mw. 3. Lithium ion battery energy storage system is facing the challenge of state grid is expected, the performance of the new generation of energy storage battery and the price will reach more than 5000 times the cycle of life, the price will be lower than 1500 yuan/KWH, efficiency will be more than 80%. Therefore, performance, price and efficiency have become application in lithium ion battery energy storage system of the main challenges. Second, in the entire energy storage battery, lithium ion batteries are also facing a sodium sulfur battery competitive pressure and liquid flow cell.
