Lithium battery energy storage market has great potential, and energy storage lithium technology is maturing. With the development of new energy Internet, large-scale centralized renewable energy, distributed generation and micro-grid power generation, FM auxiliary services, etc. have huge demand for energy storage lithium batteries. 2018 will be the starting point for the commercialization of energy storage, and the lithium battery energy storage market is expected to usher in a rapid development stage.
First, what is the demand for lithium battery energy storage market?
China's energy storage market is huge, and the China Energy Outlook 2030 released by the China Energy Research Association shows:
The new energy installed capacity will contribute 90% of the energy consumption increment. The power of the supporting energy storage device is calculated according to 15% of the wind power and photovoltaic installed capacity. By 2030, the demand for energy storage lithium battery is expected to reach 850 million kWh, in kilowatt hours. Energy storage system (lithium battery) price calculation of 1,200 yuan, China's scenery storage energy market space is expected to reach 1 trillion yuan. In the next five years, the cumulative demand for energy storage batteries is 68.05GWH.
The global lithium battery energy storage industry still maintains a relatively fast development speed. In 2017, there were 156 new energy storage projects (including operation, under construction, and planned projects), and the installed capacity increased by 78% compared with the previous year. Rapid development is inseparable from the promotion of policies, especially the implementation of subsidies is an important energy to stimulate the development of the industry. In countries such as Europe and the United States, the energy storage industry has been included in the national strategic height, these countries are passing strong industrial policies and continuous investment, Constantly promoting the innovation and research and development of the energy storage industry, China's lithium battery energy storage market is expected to usher in a rapid development stage.
Second, lithium battery energy storage technology continues to mature
Lithium battery energy storage technology is developing in a large-scale, high-efficiency, long-life, low-cost, non-polluting direction. So far, various energy storage technologies have been proposed and developed for different fields and different needs. Satisfy the application. Lithium-ion battery energy storage is currently the most feasible technical route.
The lithium iron phosphate battery pack has relatively high energy density and strong endurance, and with the application of lithium iron phosphate cathode material, the life and safety of the traditional carbon negative lithium ion battery have been greatly improved, and it is preferred for energy storage. .
Due to the research and development of new materials for lithium batteries, the continuous maturity and innovation of production technology, and the active participation of relevant scientific research institutions and industries, lithium-ion batteries have significant advantages such as high specific energy, long cycle life and green environmental protection at low cost. Become the main supporting power source for all kinds of advanced energy storage products.
Third, lithium battery energy storage technology application
At present, the application fields of energy storage technology mainly have the following four aspects:
First, the power supply side, its main role is to stabilize the power fluctuations of new energy power generation, improve the quality of new energy power, reduce abandoned light and wind, and improve the economic benefits of new energy power generation.
The second is the grid side, participating in the power grid frequency regulation or peak regulation, as a black start power supply, its adjustment is fast and flexible.
The third is the load side. The current peak and valley arbitrage is also a main push product, cutting peaks and filling valleys, shifting load, improving equipment utilization, reducing demand for power supply capacity, and delaying investment in distribution network.
The fourth is the micro-grid, the two-way regulation of the operation of the microgrid, and the indispensable compensation part of the micro-grid island operation is the energy storage system.
In the current application field, the three major areas of lithium battery energy storage are: large-scale wind energy storage, backup power supply for communication base stations, and household energy storage. The backup power supply field of communication base stations currently accounts for a large proportion, and household energy storage The wave of 'energy family' set up by Tesla has a large space for further development and expansion. Large-scale scenery and energy storage are not very strong in the short term.
Fourth, how to choose lithium battery energy storage power?
First, look at the appearance, workmanship, size and process of the lithium battery energy storage power supply. Look at the appearance of the workmanship? We can look at the seam of the shell, see the seam line width is not wide, whether there is burr, and There are no oil stains, feel good to the touch, advanced craftsmanship is very comfortable, after polishing, rubber oil polishing material has good hand feeling, and the insulation performance is also very strong.
Second, choose the manufacturer, choose the brand. There are many domestic lithium battery energy storage power brands, but the quality is difficult to see from the appearance. In this case, everyone should do more homework before choosing, go to the online to check the manufacturer information. . Energy storage is a lithium battery UPS manufacturer, with lithium batteries as the energy storage power source, which is trustworthy.
Third, look at the product parameters. The most important parameter of the lithium battery energy storage power supply is the battery inside, it is best to choose the power supply of lithium iron phosphate battery.
Well, the introduction of lithium battery energy storage power is here. The energy storage lithium battery pack is widely used in small computer rooms, weak room and other room division systems, new energy outdoor sites, communication base stations, indoor and outdoor airless stations, radio and television. , unmanned sites such as troops, oil and meteorology.
