Lithium iron phosphate batteries in the field of communication power supply are bound to replace lead-acid batteries

In the field of communications, there is a "very important" but "not-so-obtrusive" part, that is, battery companies that provide backup power for the majority of operators. After years of development, the current battery technology used in the communication field includes not only traditional lead-acid battery technology, but also various new technologies such as lithium ion batteries, fuel cells, and flow batteries. Lithium iron phosphate battery is one of them. The communication backup power supply is very important to the communication industry. It is assembled in the computer room of each base station in the form of a battery cabinet to provide power when the mains of the base station is interrupted to ensure the normal operation of the base station and smooth communication. It is understood that at present, most operators are still using lead-acid batteries. Lead-acid batteries have been used in the communications industry for nearly 25 years, and their drawbacks have become increasingly apparent, especially for the environment of the computer room and subsequent maintenance. The editor believes that with the continuous development of technology and the continuous reduction of costs, there will be new technologies to replace lead-acid batteries in the future. Therefore, in the future communication power supply field, operators will accept and use lithium iron phosphate on a large scale. battery. The lithium iron phosphate battery popularized in the communication field adopts the patented technology of large-capacity, laminated, flexible packaging, and a lean liquid lithium-ion battery. Compared with lead-acid batteries, lithium iron phosphate battery communication power products have a small footprint and high energy density. , Long cycle life, safety, reliability, and environmental protection advantages. Through this design, the battery volume becomes smaller and the weight becomes lighter, which can solve the space and load-bearing problems of the operator's computer room. In addition, due to the change of battery materials, it can be used as a backup power source in outdoor stations, and the humidity and temperature have less influence on it, and can adapt to more complex working environments. More importantly, lithium iron phosphate batteries are more environmentally friendly than lead-acid batteries. Lithium iron phosphate batteries can be customized according to the different needs of customers, and different batteries can be assembled into battery modules, and then designed into different backup power solutions, and then provide backup power to the base station. Lithium iron phosphate battery is more suitable to be configured as a backup power supply or integrated power supply. It can be conveniently hung on the corridor wall, installed on the roof, and fixed on the wire and light pole. The built-in lithium iron battery can be selected in the range of 30AH~100AH according to different scenarios and power requirements. The product has stable and reliable performance such as conversion time below 10mS, long backup time, noise below 40dB, efficiency above 90%, normal use at a high temperature of 60 degrees, and service life of more than 8 years. Although lithium iron phosphate batteries have entered the communications industry for a long time, operators have not widely promoted their applications. In view of the broad application prospects of lithium iron phosphate batteries in the communications industry, in recent years, major operators such as China Mobile and China Unicom Telecom have established various test sites for iron-lithium batteries based on preliminary demonstrations by research institutes and battery manufacturers to explore iron-lithium batteries. Energy-saving and emission reduction benefits of batteries. Therefore, it is imperative to be familiar with the technical characteristics of lithium iron phosphate batteries and master the design and configuration principles of lithium iron phosphate batteries. Summary: At this stage, most of the lithium batteries used in the field of communication backup power are lithium iron phosphate batteries, and a small number are ternary lithium batteries. In terms of electrical performance, lithium batteries surpass lead-acid batteries. The flexible choice of lithium iron phosphate batteries and ternary lithium batteries will make the lithium battery backup power supply more widely used in the communications industry.
