Briefly describe lithium battery energy storage technology and market outlook

The lithium battery energy storage system is related to other battery energy storage systems. It has the characteristics of high energy density, wide environmental temperature habit, high charge and discharge power, and fast response speed. It has the characteristics of distributed energy storage system and DC bus power supply system. Larger advantages, the current small-scale pilot projects have already adopted lithium battery energy storage systems, such as the 230kWh lithium battery energy storage system used in the intelligent microgrid of the Yunnan Electric Power Research Institute. With the rapid development of lithium batteries, their safety and cycle times will further improve, and their prices will fall further. Lithium battery energy storage systems will also occupy more and more microgrid systems such as distributed energy storage systems and wind power systems. Critical status. 1. The market predicts that the large-scale energy storage system will be an important part of the future new energy system and smart grid, and the energy storage battery is the key to the large-scale energy storage system. Lithium batteries have the advantages of high energy density, good charge and discharge power, low self-discharge rate, stable output, and green environmental protection. They have now become the main stream treatment method for energy storage batteries. The global market size of lithium batteries in 2011 was 1,699.3 billion yen, an increase of 108.2% compared to 2010 in the next few years. The trend of the lithium battery industry moving to my country on a global scale will become more and more significant, and most lithium battery factories have also listed power lithium-ion batteries/energy storage batteries as the direction of transformation. According to another statistical data, by 2015, the production of lithium batteries will exceed 5 billion Ah, and the scale of the market is about 15 billion U.S. dollars. 2. Challenges faced by the lithium battery energy storage system. The State Grid’s expectations for the performance and price of next-generation energy storage batteries are that the cycle life reaches more than 5000 times, the price reaches below 1,500 yuan/kWh, and the power reaches more than 80%. The current battery It is still difficult for the energy storage system to reach such an index. Therefore, performance, price and power have become a major challenge for the use of lithium batteries in energy storage systems. Secondly, in the entire energy storage battery system, lithium batteries are also facing competitive pressure from sodium-sulfur batteries and flow batteries.
