What are the applications of LiFePO4 in the energy storage market?
Lithium iron phosphate battery has a series of unique advantages such as high operating voltage, high energy density, long cycle life, small self-discharge rate, no memory effect, green and environmental protection, and supports stepless expansion.
Suitable for large-scale electrical energy storage, renewable energy power station power generation safety to the grid, power grid peaking, distributed power stations, UPS power supply, emergency power systems, and other fields have good prospects for application.
With the rise of the energy storage market, in recent years, some power battery companies have laid out the energy storage business, to develop new applications for the lithium iron phosphate market.
On the one hand, lithium iron phosphate due to its ultra-long life, use safety, high capacity, green and other characteristics, can be transferred to the field of energy storage will extend the value chain and promote the establishment of a new business model.
On the other hand, lithium iron phosphate supporting energy storage system has become the mainstream choice of the market. According to the report, lithium iron phosphate batteries have been tried for electric buses, electric trucks, user side, and grid side frequency regulation.
1, wind power, photovoltaic power generation, and other renewable energy generation safety to the grid
The inherent randomness, intermittency, and volatility of wind power generation determine that its large-scale development will certainly have a significant impact on the safe operation of the power system. With the rapid development of the wind power industry, especially since most of the wind farms in China are "large-scale centralized development and long-distance transmission", the grid-connected power generation of large wind farms poses a serious challenge to the operation and control of large power grids.
Photovoltaic power generation is affected by ambient temperature, sunlight intensity, and weather conditions, and photovoltaic power generation shows random fluctuations. Therefore, high-capacity energy storage products become a key factor in solving the contradiction between the power grid and renewable energy generation.
Lithium iron phosphate energy storage system(ESS) has the characteristics of fast working condition conversion, flexible operation mode, high efficiency, safety, and environmental protection, strong scalability, etc. It has carried out engineering applications in the national scenery storage and transmission demonstration project, which will effectively improve equipment efficiency, solve local voltage control problems, improve the reliability of renewable energy power generation and improve power quality, and make renewable energy become a continuous and stable power supply.
With the continuous expansion of capacity and scale, integration technology continues to mature, and the cost of energy storage systems will be further reduced after long-term testing of safety and reliability, lithium iron phosphate energy storage systems are expected to be widely used in wind power generation, photovoltaic power generation and other renewable energy generation safety to the grid and improve power quality.
The main means of power grid peaking have been pumped storage power plants. As pumped storage power plants need to build two reservoirs, the upper and lower reservoirs, subject to geographical constraints, are not easy to build in the plains and cover an area of large, high maintenance costs.
The use of a lithium iron phosphate energy storage system instead of the pumped storage power station, to cope with the peak load of the power grid, is not subject to geographical constraints, free site selection, less investment, less land area, low maintenance costs, in the process of grid peaking will play an important role.
3、Distributed power station
The defects of large power grids themselves make it difficult to guarantee the quality, efficiency, safety, and reliability requirements of power supply. Important units and enterprises, often require dual or even multiple power supplies as backup and protection.
Lithium iron phosphate energy storage system can reduce or avoid power outages due to grid failures and various unexpected events, playing an important role in ensuring a safe and reliable power supply for hospitals, banks, command, and control centers, data processing centers, chemical material industries, and precision manufacturing industries.
4、UPS power supply
China's continued rapid economic development is brought about by the decentralization of the UPS power supply user demand, making more industries and more companies have a continuous demand for UPS power supply.
Lithium iron phosphate batteries relative to lead-acid batteries, with a long cycle life, are safe and stable, green, small self-discharge rate, etc., with the integration of technology, continues to mature, the cost continues to reduce, lithium iron phosphate batteries in UPS power supply will be widely used.
