In recent years, the new energy industry has developed rapidly. The application scenarios of lithium-ion batteries can be divided into three categories: consumption, power, and energy storage. Currently, energy storage battery technology is developing rapidly, and the lithium-ion battery energy storage field has always been closely watched. Once a breakthrough is achieved, it will have a significant impact on the development of new energy, the operation and control of the power grid, and terminal energy usage.
As an emerging application scenario, the energy storage lithium-ion battery has also gradually received attention. With its high energy density, high conversion efficiency, and rapid response, lithium-ion batteries have a broad prospect in the application of large-scale energy storage systems. In the future, the lithium-ion battery technology for energy storage will be widely applied in the new generation of power systems.
Grid-connected new energy requirements, including improving power quality and smoothing power waves; following new energy generation plans and combining with the predicted generation curve; peak shaving to maintain continuous new energy generation; combining with photovoltaic and wind power to smooth power output, increase the acceptance rate of new energy, fully utilize new energy, and reduce harmful gas emissions.
Adjusting the load curve, peak shaving, and improving the utilization of distribution equipment and lines.
Participating in grid frequency regulation and improving the power supply level of the large power grid.
As an important component of microgrids, it solves people's problems and improves the quality of local power supply.
An important element of a smart grid.
Special needs (such as uninterrupted power supply for photovoltaic power plants, disaster areas, subway stations, airports, military bases, etc.)
Data center. The lithium-ion battery can be charged and discharged many times quickly, and they have the characteristics of high density. During the power valley period of municipal power consumption, they can store electricity. When the power peak comes, they can transmit the stored power to the data center, thereby reducing the pressure of the power peak on the power grid. This function will make significant contributions to green energy conservation and PUE, and can simultaneously meet the dual requirements of the government and data center users for PUE and TCO.
Distributed energy storage, used for peak shaving of factories and buildings.
Backup power supply.
The application of energy storage cells made of lithium can change the traditional energy supply and consumption mode and has significant implications for promoting the transformation of energy structure, energy revolution on the consumption side, ensuring energy security, and achieving energy-saving and emission reduction goals. With the continuous development of lithium battery technology and the strong support of lithium-ion batteries and new energy technologies by countries around the world, large lithium-ion battery energy storage system devices have been researched and applied more and more.
The energy storage market includes large-scale energy storage, home energy storage, backup power storage, and so on. Under existing technology, the cost-effectiveness of lithium-ion batteries in the field of backup power storage has significantly improved, and the fields of backup power storage and home energy storage are currently more suitable for the application of lithium-ion batteries. Among them, the energy storage, especially the market of backup power storage, is particularly broad. The future market potential of the lithium-ion battery energy storage is unlimited.
With the development and extensive application of various lithium-ion battery energy storage technologies in the future, energy storage cells will be applied to various links of the power system "generation, transmission, distribution, use, and adjustment" and may change the production, transportation, and usage modes of the existing power system, helping the traditional power system to transform into a new generation of electricity systems that are "widely interconnected, intelligently interactive, flexible and safe and controllable." New energy storage cell technology has become the current research focus and technological frontier, and is expected to significantly improve the performance of lithium-ion batteries for energy storage and promote large-scale application of lithium-ion batteries for energy storage.
