5G commercialization applications are getting closer and closer, and base station construction will drive demand for LiFePO4 batteries above 155GWh. 5G commercial applications are getting closer and closer, and the entire industry chain is actively operating to meet new technical standards. The data shows that in the past three years, the domestic network operation and support costs have increased by more than 10% annually, of which energy consumption accounts for about 12%.
In the case of such a large increase in operation and maintenance costs, the state requires a reduction in tariffs, so operation and maintenance costs become a key development point. In 2018, the China Tower has stopped purchasing lead-acid batteries and used batteries in a unified procurement process. As the construction of 5G base stations accelerates, the demand for energy storage LiFePO4 batteries will increase significantly.
According to the plan, China Telecom and China Unicom's 5G base stations will be more than twice the current number of 4G base stations, while China Mobile will be more than four times the current level. According to the data of each operator's 2018 annual report, there are at least 14.38 million base stations in China that need to be built or modified.
In addition, due to the significant increase in energy consumption of 5G base stations, it means that 14.38 million sets of backup energy systems need to be improved. According to the 5GC-band single-station power consumption of 2700W and emergency time of 4h, the market has at least 155GWh battery storage space. In order to ensure the stable use of 5G communication equipment, the storage power of 3-4h is generally reserved for the macro base station, and the power supply voltage is 48V. The large-scale construction directly drives the demand for energy storage batteries. Compared with lead-acid batteries, it can be seen that the advantages of LiFePO4 battery storage in 5G communication base stations are more obvious, and the future application prospects are broader.
Compared with ladder lithium batteries, lead storage batteries have the disadvantages of short service life, low performance and a large amount of heavy metal lead. Although the current price of LiFePO4 battery is still higher than that of lead storage batteries, its charge and discharge times, service life, and volume and weight advantages can make up for the high price defects, and the comprehensive use cost is better than that of lead storage batteries.
In 2018, the company has stopped purchasing lead-acid battery base station power supply and changed to purchase lithium battery. According to the plan of the Iron Tower Company, it will continue to expand the use of lithium batteries in 2019. It is expected to replace 150,000 tons of lead batteries and more than 50,000 tons of decommissioned power batteries. Although the base station power supply field is the demand side of the traditional lead storage battery, due to the national policy direct conversion, the growth rate in this field will be shifted to the lithium elevator secondary utilization. Although the base station power data will accelerate with the 5G investment, the statistical caliber cannot distinguish whether it is a lead battery or a lithium elevator. It is expected that with the gradual expansion of LiFePO4 batteries and the harmless treatment requirements of environmentally friendly batteries, the application of lead storage batteries at base stations will continue to be compressed.
In short, it is expected that with the decommissioning of large-volume lithium-electric battery and the accumulation of experience, the lithium battery will completely replace the lead battery in the field where the performance requirements of the base station and backup power supply are low. 5G communication base station will drive the growth of LiFePO4 battery energy storage industry!
