China Energy Storage Network News: This year, lithium iron phosphate batteries are not only on fire in the new energy vehicle market, but their demand for 5G base stations has also risen sharply.

On March 11, China Tower Co., Ltd. (hereinafter referred to as “China Tower”) issued the “2020 Procurement Announcement on Intensive E-commerce Procurement of Lithium Iron Phosphate Battery Pack Products for Backup Power”, and will bid for the procurement of 2GWh lithium iron phosphate battery packs product. Earlier, China Mobile Communications Group Co., Ltd. also issued an announcement that it plans to purchase a total of 610.2 million Ah (specification 3.2V) of lithium iron phosphate batteries for communications that do not exceed 2.508 billion yuan.

Public information shows that the demand for lithium iron phosphate for newly built and renovated 5G base stations in 2020 is about 10GWh. The market demand for lithium iron phosphate batteries will continue to increase in the future.

Industry insiders pointed out that compared with the lead-acid batteries used in 4G base stations, lithium iron phosphate batteries have obvious advantages in terms of safety, cycle life, fast charging and discharging, etc., which can reduce dependence on mains capacity expansion and transformation, and reduce network construction and Operating cost is currently the most suitable technical route for domestic 5G base station energy storage batteries.

In 5G base station application scenarios, the “overwhelming” advantage of lithium iron phosphate batteries has always been recognized in the industry.

“From a technical analysis, lithium iron phosphate batteries have long cycle life, fast charge and discharge speed, and high temperature resistance, which can reduce operating costs and improve operating efficiency for 5G base stations.” said Tang Chuanwen, sales director of Shanghai Electric Guoxuan New Energy Technology Co., Ltd. .

He added: “Generally, lead-acid batteries have a cycle life of 3-5 years, with 500-600 charge and discharge times, while lithium iron phosphate batteries have a cycle life of more than 10 years and charge and discharge times of more than 3000 times. That is to say, During the life cycle of the base station, if lead-acid batteries are used, the batteries need to be replaced, while the lithium iron phosphate batteries do not need to be replaced.

In this regard, Meng Haixing said: “Although the cost of lithium iron phosphate batteries is 1-2 times higher than that of lead-acid batteries at this stage, the cost of lithium iron phosphate batteries is only 1% of that of lead-acid batteries under the service life of 5000 cycles. /3. From the perspective of long-term economic benefits, the use cost of lithium iron phosphate batteries is lower.”

Not only that, compared with lead-acid batteries, lithium iron phosphate batteries are also superior in terms of charge and discharge speed. Meng Haixing pointed out that the charging speed of lithium iron phosphate batteries is 10 times that of lead-acid batteries, which will greatly save the charging time of base station backup power batteries.

It is understood that as an energy storage battery, lithium iron phosphate batteries can also store electricity during the low valley period at night and release it during peak hours during the day to achieve peak-shaving and valley-filling and further reduce base station electricity costs.
