Energy storage battery refers to a battery that converts chemical energy into electrical energy and has the function of energy storage. Energy storage batteries can store electrical energy in the battery when charging, and then release the stored electrical energy when needed to meet the needs of different application scenarios. Energy storage batteries mainly include electric energy storage, transportation energy storage, home energy storage, outdoor portable energy storage and other fields. Due to its unique advantages, lithium iron phosphate batteries are usually widely used in the field of energy storage batteries, mainly for the following reasons:
1. Cost advantage
Compared with other types of batteries, the material cost of lithium iron phosphate batteries is low and the production process is relatively simple;
2. High security
Due to the easy energy storage battery is generally relatively large, so the safety requirements of the battery is higher, compared with the terpolymer lithium battery, lithium iron phosphate battery has good thermal stability, and will not produce flammable gas when overheating or short circuit;
3. Long cycle life
The cycle life of lithium iron phosphate battery is more than 2000 times, and the use of lithium iron phosphate battery can reduce the maintenance cost and replacement cycle of the energy storage battery, and improve the stability and reliability of the battery.
4. High energy density
The single energy density of lithium iron phosphate batteries reaches about 150Wh/kg, compared to the single energy density of lead-acid batteries and nickel-cadmium batteries is only about 50Wh/kg. Therefore, the use of lithium iron phosphate batteries can reduce the volume and quality of the energy storage system, and improve the portability and utilization of the system.
5. Environmental protection and no pollution
Lithium iron phosphate battery does not contain harmful heavy metal elements, such as lead, cadmium, etc., friendly to the environment, the use of the process, will not produce toxic and harmful substances, has a high recycling value.
In short, lithium iron phosphate batteries are widely used in the field of energy storage batteries because of their high safety, low cost, long life, high energy density, environmental protection and pollution-free advantages.
