Energy storage battery refers to a battery that converts chemical energy into electrical energy and has energy storage function. Energy storage battery 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 power energy storage, transportation energy storage, home energy storage, outdoor portable energy storage and other fields. Due to its unique advantages and characteristics, lithium iron phosphate batteries are usually widely used in the field of energy storage batteries. There are mainly the following reasons:
1. Cost advantage
Compared with other types of batteries, lithium iron phosphate batteries have lower material costs and relatively simple production processes;
2. High safety
Since energy storage batteries are generally easy to be used, higher safety requirements are placed on batteries. Compared with ternary lithium batteries, lithium iron phosphate batteries have good thermal stability and will not produce flammable gases when overheated or short-circuited;
3. Long cycle life
The cycle life of lithium iron phosphate batteries is more than 2,000 times. The use of lithium iron phosphate batteries can reduce the maintenance cost and replacement cycle of energy storage batteries and improve the stability and reliability of batteries;
4. High energy density
The single-cell energy density of lithium iron phosphate batteries reaches about 150Wh/kg. In comparison, the single-cell 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 mass of energy storage systems and improve the portability and utilization of systems.
5. Environmentally friendly and pollution-free
Lithium iron phosphate batteries do not contain harmful heavy metal elements such as lead and cadmium, are environmentally friendly, and do not produce toxic and harmful substances during use, and have 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.
