Lithium battery, which uses the lithium iron phosphate as a positive electrode material, owes the advantages as following:1. high operating voltage 2.high energy density 3.long cycle life 4.good safety performance 5.low self-discharge rate 6.no memory effect So,what could the lithium batteries achieve in the energy storage market? Besides,the battery also supports stepless expansion, as well as being suitable for large-scale electric energy storage.
Have good application prospects in the following fields:
1: Renewable energy power stations
2: Power grid peak regulation
3:Distributed power stations
4:UPS power supplies
5:Emergency power supply systems
Wind power generation has features of inherent randomness, intermittence and fluctuation. The features determine that the large-scale development of wind power generation will have a great impact on the safe operation of power system. The wind power industry develops rapidly. Most wind farms in China are large-scale centralized development and long-distance transmission, that would be a severe challenge to the operation and control of large-scale power grid. Being influenced by ambient temperature, solar illumination intensity and weather conditions, photovoltaic power generation has the feature of random fluctuation. With the trend of decentralized development, low-voltage on-site access and large-scale development, medium-high voltage access, higher requirements are becoming more and more important for the peak regulation of power grid and the safe operation of power system. Therefore, large capacity energy storage product, as a key factor, could solve the contradiction between power grid and renewable energy generation. The characteristics of lithium battery energy storage system are as follow:
1. fast conversion of working conditions
2. flexible operation mode, high efficiency
3. .safety
4. environmental protection
5. strong scalability.
The cost of the energy storage system will be further reduced for: 1.continuous expansion of capacity and scale 2.the maturity of integrated technology. The lithium iron phosphate battery energy storage system is expected to be used in wind power and photovoltaic power generation after long-term safety and reliability tests. It has been widely used in the safe grid connection of energy generation and the improvement of power quality. What’s more, the lithium iron battery also supports stepless expansion, suitable for large-scale electric energy storage.Have good application prospects in the following fields:
1: Renewable energy power stations
2: Power grid peak regulation
3:Distributed power stations
4:UPS power supplies
5:Emergency power supply systems
The wind power generation, photovoltaic power generation and other renewable energy power stations are intermittent and fluctuating. It determines that their large-scale development will inevitably have a great impact on the safe operation of the power system.
The main means of power grid peak regulation has always been pumped storage power stations. As the pumped-storage power station needs two reservoirs, the upper and lower reservoirs, which are greatly restricted by geographical conditions, it is difficult to construct in the plain area. Also, it needs a large area of land and the maintenance cost is high.Instead, the lithium iron phosphate battery energy storage system has the advantages of not being limited by geographical conditions, free site selection, less investment, less land occupation and low maintenance cost. It is important in the process of power grid peak regulation.
It is difficult to guarantee the quality, efficiency, safety and reliability requirements of power supply for the defects of the large power grid itself. Dual power supplies or even multiple power supplies are often required as backup and protection for important units and enterprises. The solar lithium battery energy storage system can reduce or avoid power outages caused by grid failures and various unexpected events. So, it is an important role to ensure safe and reliable power supply in hospitals, banks, command and control centers, data processing centers, chemical materials industry, and precision manufacturing industries.
The continuous and rapid development of China's economy has led to the decentralization of requirement in UPS power supply. More and more enterprises and industries have continuous demand for UPS power supply. Compared with lead-acid batteries, lithium batteries have the advantages of : 1. long cycle life 2. safety 3.stability 4.green environmental protection 5.low self-discharge rate. For the continuous maturity of integration technology and the continuous reduction of cost, lithium batteries will be widely used in the future.
With the rise of the energy storage market, in recent years, some power battery companies have deployed energy storage business to open up new application markets for lithium iron phosphate batteries. On the one hand, due to the characteristics: 1.ultra-long life 2.safety 3.large capacity 4.green environmental protection, lithium iron phosphate can be transferred to the energy storage field, which will extend the value chain and promote the establishment of a new business model. On the other hand, the lithium iron phosphate battery has become the mainstream choice in the market.
