Analysis of li-ion battery energy storage market development

Source: 2020 - 03 - 23 clicks desire: the development of the energy storage market ( A) Electrochemical energy storage market profile electric energy storage is to point to to meet the application requirements of electric power system in the power system reactive power energy storage technology in kilowatt above. In terms of energy storage, energy storage can be divided into physical energy storage, electrochemical energy storage and three types of electromagnetic energy storage. Physical energy storage mainly includes pump energy storage, compressed air energy storage and flywheel energy storage. Electromagnetic energy storage response speed, can in a short time, high power, electricity cycles, including the capacitor energy storage and superconducting energy storage. In addition to lithium batteries, electrochemical energy storage including sodium sulfur battery, lead batteries and fluid flow. 2. The national industrial policy escalated in energy storage industry in China's strategic layout can be traced back to 2005 years of the renewable energy development guidance catalogue, including oxidation reducing fluid energy storage battery and the underground thermal energy storage system. In 2010, energy storage industry development are included in the bill for the first time. In those days the renewable energy law 14th amendment expressly provide 'power grid enterprise should' development and application of the smart grid and energy storage. First appeared in 2011, the national 'twelfth five-year plan for energy storage, was placed on the national strategic emerging industry development planning ', the renewable energy development planning' and 'energy development strategy plan of action ( 2014 - 2020). ', 'a number of views on further deepening the reform of electric power system, such as the policy focus on innovation and development in the field, with a focus on the integration and smart grid technology, storage as one of the important ways to improve the renewable energy was put forward. Since 2016, the application of energy storage at the national level to further expand. Power demand side management method, Revised edition) Issued by the six ministries, including the National Development and Reform Commission proposed 'by deepening electric power demand side management, the key should develop alternative energy storage and power relations, and large-scale friendly interaction between supply side and user side should be to promote'. In October 2017, on the guidance to promote the development of energy storage technology and industry in China, become the first guidance document storage industry in China. Therefore, energy storage as an important field, alone in the national development and guidance. Documentation to identify five key tasks, including promoting energy storage technology and equipment research and development, promote the energy storage, improve the level of the use of renewable energy, promote energy storage to improve the flexibility and stability of power system, improve energy storage energy use level of intelligence, and promote diversified energy storage application support network. ( 3) The development of new energy vehicles, to accelerate the process of energy storage applications of battery costs significantly reduced is the premise of a massive expansion of electrochemical energy storage capacity. The development of new energy vehicles in China, and the resulting power battery capacity expansion, the lithium battery cost reduce rapidly, greatly accelerate the process of the application of electrochemical energy storage. According to bloomberg, 彭博财经) The latest release of the long-term energy storage outlook, 长期 储能前景) Report, between 2010 and 2016, the cost of the battery pack from $1000 per kilowatt hour fell to $227 per kilowatt-hour, it also improved the people's expectations of lithium ion battery potential. According to the forecast, from 2018 to 2030, the price of the lithium ion battery will continue to fall 52%, which makes the cost of the energy storage system falling faster than expected. By 2050, $548 billion will be invested in battery energy storage system, two-thirds will be used in the power grid, the rest used for households and businesses. With the development of new energy vehicles, greatly reduce the cost of lithium-ion batteries, lithium batteries of mainstream become unshakable. Prices further down will make the battery into the family, to meet the change of energy demand and supply.
