Advantages of lithium batteries in the field of energy storage

2022-11-186

The working principle of lithium-ion batteries refers to the principle of charge and discharge: when a lithium-ion battery is charged, lithium ions are generated on the positive electrode of the battery, and the generated lithium ions move to the negative electrode through the electrolyte. The carbon as the negative electrode has a layered structure, it has many micropores, and the lithium ions that reach the negative electrode are embedded in the micropores of the carbon layer, and the more lithium ions are embedded, the higher the charging capacity.

Advantages of energy storage lithium-ion batteries: Energy storage lithium-ion batteries are better than lead-acid batteries in terms of energy density, cycle life, cleanliness and environmental protection. In the future, energy storage lithium-ion batteries will achieve large-scale production, safety and stability will be better and better, the price will be lower and lower, and the competitiveness will naturally become stronger and stronger. Energy storage lithium-ion batteries will play a pivotal role in the field of backup power supply for communication base stations.


The equipment of energy storage lithium-ion battery emphasizes the battery capacity, especially the operation stability and service life, and considers the consistency of the battery module, and the battery material should pay attention to the expansion rate and energy density, and the uniform performance of the electrode material, so as to pursue the long life and low cost of the overall energy storage equipment.

Disadvantages of energy storage lithium-ion batteries:

1. The safety of energy storage lithium-ion batteries is poor and the risk of explosion occurs.

If the lithium-ion battery is pierced by a hard object, the lithium ions inside it will react with oxygen chemically, resulting in a fire or even an explosion; to prevent high temperature and fire roasting, in the hot summer or exposed to the car, the ambient temperature of the lithium-ion battery will be higher than its normal storage temperature, causing the lithium-ion battery to catch fire and explode.

2. The conditions for energy storage lithium-ion batteries are high and the cost is high.

3. Too high or too low temperature will affect the performance of energy storage lithium-ion batteries, and may even shorten the service life of the battery.
