Lithium iron phosphate battery in the field of communication power supply is bound to replace lead-acid battery. Compared with traditional lead-acid batteries, lithium iron phosphate batteries used in the field of communication power supply have the advantages of high energy density, strong safety, good high temperature performance, high power output, long cycle life and environmental protection. Lithium iron phosphate batteries used in communication generally adopt modular structure. A 48v/50ah battery pack module is generally composed of 15 or 16 50ah battery cells in series.

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

In the field of communication, there is a "very important" but "inconspicuous" part, that is, the battery enterprises that provide backup power for the majority of operators. After years of development, the battery technology used in the current communication field includes not only the traditional lead-acid battery technology, but also various new technologies such as lithium-ion battery, fuel cell and liquid flow battery. Lithium iron phosphate battery is one of them.

The communication backup power supply is very important to the communication industry. It is assembled in each base station machine room in the form of battery cabinet to provide power in the case of power interruption of the base station, so as to ensure the normal work and smooth communication of the base station. It is understood that at present, most operators are still using lead-acid batteries. Lead-acid batteries have been used in the communication industry for nearly 25 years, and their disadvantages are increasingly apparent, especially with high requirements for the computer room environment and later maintenance. The editor of Sunergy electric believes that with the continuous development of technology and the continuous reduction of cost, there will be new technologies to replace lead-acid batteries in the future, so operators will accept and use lithium iron phosphate batteries on a large scale in the field of communication power supply in the future.

The lithium iron phosphate battery popularized and used in the communication field adopts the patented technology of high-capacity, laminated, soft packaging and lean liquid lithium-ion battery. Compared with lead-acid battery, lithium iron phosphate battery communication power supply products have the advantages of small floor space, high energy density, long cycle life, safety, reliability and green environmental protection. Through this design, the battery becomes smaller and lighter, which can solve the space and load-bearing problems of operators' machine rooms.

In addition, due to the change of battery material, it can be used as a backup power supply in outdoor stations. Humidity and temperature have little impact on it, and it can adapt to more complex working environment. More importantly, lithium iron phosphate batteries are more environmentally friendly than lead-acid batteries. Lithium iron phosphate battery can be customized according to the different needs of customers. Different cells are 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 standby power supply or integrated power supply, which can be conveniently hung on the corridor wall, installed on the roof, and fixed on wires and lamp poles. The built-in iron lithium battery is selected in the range of 30ah~100ah according to different scenarios and backup requirements. The product has stable and reliable performance with conversion time below 10ms, long standby time, noise below 40dB, efficiency above 90%, normal use at 60 ℃ and service life of more than 8 years.

Although lithium iron phosphate battery has entered the communication industry for a long time, it has not been widely used and promoted by operators. In view of the broad application prospects of lithium iron phosphate batteries in the communication industry, in recent years, major operators such as China Mobile and China Unicom have established a variety of test sites for lithium iron batteries under the preliminary demonstration of research institutes and battery manufacturers to explore the energy-saving and emission reduction benefits of lithium iron batteries. Therefore, it is imperative to be familiar with the technical characteristics of lithium iron phosphate battery and master the design and configuration principles of lithium iron phosphate battery.

Summary: at this stage, most of the lithium batteries used in the field of communication backup power supply are lithium iron phosphate batteries, and a few are ternary lithium batteries. In terms of electrical performance, lithium batteries surpass lead-acid batteries. Flexible selection of lithium iron phosphate battery and ternary lithium battery will make the lithium battery backup power supply more widely used in the communication industry.
