The main function of lithium battery UPS energy storage is to supply power to electrical appliances. Most of the time, the lithium battery UPS serves the function of stabilizing voltage between the grid and the load, and only releases the stored energy to provide for the load when the grid is interrupted.
Lithium batteries have not been the primary choice for UPS power storage for a long time. Before them, lead acid batteries were the main choice. However, in just a few short years, lithium batteries have risen up and gained the favor of both users and the market. More and more manufacturers and users now prefer lithium battery UPS over lead acid UPS.
Long service life: Lithium battery UPS uses lithium battery as its energy storage source. Due to its low strain sensitivity, lithium batteries can greatly reduce problems of structural damage caused by the repeated expansion and contraction of electrode materials. This means that the service life of lithium battery UPS energy storage is longer than that of UPS using other energy storage sources.
High safety: The working potential of lithium batteries is high, which makes it difficult for lithium dendrites to form on the negative pole during the charging process, even in the case of overcharging. This greatly enhances the safety of lithium battery UPS.
Large energy density: The volumetric energy density and specific energy density of lithium batteries can reach 450 W.h/dm3 and 150 W.h/kg, respectively, and the overall energy density is still increasing.
Low self-discharge: With initial electrical charge, a battery will lose a certain amount of energy when left unused under specified environmental conditions. The difference in remaining energy compared with the original energy is the self-discharge rate of the battery. Lithium batteries have a higher voltage and lower self-discharge rate, making this one of the major advantages and benefits of lithium battery UPS energy storage.
No environmental pollution: The materials used in energy storage lithium batteries do not contain harmful metals such as cadmium, lead, mercury, and other pollutants. Lithium batteries do not produce pollution during production and use, and are unlikely to pollute water sources and soil during the recycling process of waste batteries.
The main advantage of lithium battery UPS energy storage lies in the superiority of lithium batteries compared to other batteries. The excellent performance and compact design of lithium batteries have a significant impact on the overall performance of lithium battery UPS. The smaller size and volume of energy storage lithium batteries compared to other batteries make lithium battery UPS lighter and smaller. The advantages of lithium batteries usually apply to lithium battery UPS as well.
