The use of lithium batteries in the field of communication

Important use of lithium batteries in communications: In terms of 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 metals. There is no outbreak of pollutants during the processing and use of lithium batteries. In order to ensure human health, the recycling process of waste batteries will not cause water and soil pollution. The cycle life, high temperature characteristics, charge-discharge rate function and energy density of lithium batteries are all very good, far superior to lead-acid batteries. For example, the volume and components of a lithium battery with the same capacity are half to one third of that of a lead-acid battery, and can be connected and placed arbitrarily. There are no special requirements for building space, bearings, etc., which greatly reduces the cost of site rental. The excellent high temperature characteristics of 48V lithium battery can reduce the power consumption of base station air conditioning equipment. The lithium battery can output more than 90% of the rated capacity within 10 minutes, and can be used for UPS or communication base station power supply. It has a short backup time and gives full play to its characteristics such as good discharge rate. The development trend of lithium batteries: backup power supplies based on 48V lithium iron phosphate batteries can be widely used in indoor and blind area coverage, second and third types of municipal power areas, short-term backup power sources, etc. for power composition, volume, cycle life and power ratio More demanding occasions. In the era of big data, scenarios with limited space such as shared stations and central computer room expansion also gradually require the participation of lithium battery backup power. In the future, with the completion of the large-scale processing of energy storage lithium batteries, the cost continues to decline, and 48V lithium iron phosphate batteries will play an increasingly important role in the backup power supply of communication base stations. With the development of electric vehicles and lithium battery energy storage business, the scale of use of lithium batteries continues to expand, the price will become lower and lower, and the competitiveness will become stronger. The application technology of lithium iron phosphate batteries is now mature, and relevant specifications and specifications have been drafted. In the future, it will replace the use of lead-acid batteries and greatly reduce the processing and protection costs of communication equipment. Lithium battery characteristics: 1. The weight of a high-energy density lithium battery is half that of a nickel-cadmium battery or nickel-hydrogen battery of the same capacity, 20-30% of a nickel-cadmium battery, and 35-50% of a nickel-hydrogen battery. 2. The working voltage of a single high-voltage lithium battery is 3.7v (average value), which is equivalent to 3 nickel-cadmium batteries or nickel-hydrogen batteries in series. 3. No pollution. Lithium batteries do not contain cadmium, lead, mercury and other harmful metals. 4. There is no metal lithium lithium battery does not contain lithium metal, so it is not restricted by air transportation rules, which hinders the transportation of lithium batteries on passenger aircraft. 5. High cycle life Under normal circumstances, the charge and discharge cycles of lithium batteries can exceed 500 times, and lithium iron phosphate (hereinafter referred to as iron phosphate) can reach 2000 times. The effect of no recall The recall effect refers to the phenomenon that the capacity of the nickel battery decreases during the charging and discharging process. Lithium batteries do not have this effect. 7. Fast charging constant current constant voltage charger, rated voltage 4.2v, can fully charge lithium battery within 1.5~2.5 hours. The newly developed lithium-phosphorus iron battery can now be fully charged in 35 minutes. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
