the advantages of energy storage lithium batteries in the field of communications

This is an era of data explosion. The main equipment continues to evolve, and network energy equipment also develops rapidly. The backup power supply to ensure the uninterrupted power supply of communication equipment also needs to speed up the pace to contribute to the era of big data.

Lead-acid batteries have been developed for more than 150 years. Because of their low cost, mature technology, and convenient maintenance. Lead-acid batteries have always been the most widely used energy storage batteries in current communication power supplies. However, lead-acid batteries are subject to theoretical characteristics and product features, it is difficult to have an obvious improvement in the future.

Even lead-acid batteries with relatively good cycle performance can only maintain a lifespan of one year in areas with poor grid quality and frequent deep cycle use. In addition, the life of a lead-acid battery greatly depends on its operating temperature. When the temperature increases, the corrosion of the electrode plate and the loss of water will be accelerated, and the life of the battery will also become shorter.

Therefore, there is an urgent need for an energy storage battery to replace the traditional lead-acid battery with excellent performance without increasing the overall cost of energy storage. At this time, lithium-ion batteries have entered people's sight. The following is a detailed introduction to the advantages of energy storage lithium batteries in the field of communications.

Lithium-ion batteries did not appear in recent years. They have been commercialized in the field of mobile phones for more than 20 years. However, lithium-ion batteries are an out-and-out new army as a backup power source at communication sites. At this stage, most of the lithium batteries used in the field of communication backup power are lithium iron phosphate batteries, and a small part is ternary lithium batteries.

Considering environmental protection, lithium batteries have natural advantages. The materials used in lithium batteries do not contain polluting metals, such as cadmium, lead, mercury, and other harmful heavy metal substances. There are no pollutants generated during the production and use of lithium batteries, which protects human health. The recycling process of waste batteries will not bring water and soil pollution.

In terms of electrical performance, lithium batteries surpass lead-acid batteries in an all-around way. The cycle life, high-temperature characteristics, charge-discharge rate performance, and energy density of lithium batteries are all excellent, far superior to lead-acid batteries. For example, the volume and weight of the same capacity lithium battery is one-half to one-third of the lead-acid battery, and it can be connected and placed arbitrarily.

There are no special requirements for building space, load-bearing, etc., which greatly reduces the cost of venue rental. . In addition, the excellent high-temperature characteristics of lithium batteries can reduce the air conditioning configuration and power consumption of the base station. After the lithium battery is stolen, the recycling value is of little value. Due to the existence of the battery management system, it cannot be used directly, reducing the risk of theft of the backup power supply.

In terms of all costs (TCO), lithium batteries are not higher than lead-acid batteries. Although the price is 2 to 4 times higher than that of ordinary lead-acid batteries, the TCO during the life cycle of lithium batteries is even lower than that of lead-acid batteries due to the advantages of long life and low maintenance and replacement costs.

In the future, with the development of electric vehicles and energy storage industries, the application of lithium batteries will continue to scale, the prices will become lower and lower, and they will become more and more competitive.

Lead-acid batteries are characterized by long floating charge life and short cycle life. In short, the less used the better. However, the grid environment in many countries and regions is not good. The daily power outage lasts for more than 2 hours. Frequent recycling will lead to a rapid decline in the life of lead-acid batteries. Lithium batteries with high cycle life are suitable for use in such environments.

Lithium batteries are used for wall-mounted power supplies and pole-mounted power supplies, which can highlight their high energy density characteristics. Lead-acid batteries have the disadvantages of occupying a large area, being heavyweight, and having high load-bearing requirements, making it more and more difficult to meet the requirements of small space scenes. The energy density of lithium batteries is 2 to 4 times that of lead-acid batteries and is particularly suitable for use in the above-mentioned environment.      
It is used in UPS or communication power supply for short-time backup, and it takes advantage of its good discharge rate. In some scenarios that use diesel engine emergency power supply, the backup power supply of UPS or communication power supply needs to have 5-10 minutes of backup power in order to back up data and switch to diesel engine emergency power supply. In this case, only battery power between 5-10 minutes is required. Guarantee a certain output power within minutes.

Lithium batteries can output more than 90% of the rated capacity within 10 minutes, while lead-acid batteries can discharge up to 30% of the rated capacity within 10 minutes. Lithium batteries can be equipped with much less capacity than lead-acid batteries to meet short-term requirements. The requirement of backup power saves space and cost.

Lithium batteries for communication energy storage need to cooperate with an excellent battery management system to be truly safe and stable.
