Why can't telecommunication lithium iron phosphate battery be used on a large scale

At present, the primary factor affecting the large-scale application of lithium iron phosphate batteries for communications is price. At present, the price of mainstream lithium iron phosphate batteries on the market is on average two to three times higher than that of lead-acid batteries, or even more than five times higher. If the iron-lithium-ion battery can indeed achieve a 10-year lifespan, the return on investment is also okay compared to the 2-year lifespan of a lead-acid battery. But in reality, operators still feel that the current prices are too expensive. Several provincial companies in my country Telecom are trialing lithium iron phosphate batteries. Relatively speaking, the scale is not too large. Between a few hundred to a thousand groups, the capacity of each group does not exceed 50 Ah. In addition to the price, the lack of sufficient actual data is another important reason why operators are temporarily reluctant to use lithium iron phosphate batteries on a large scale. It is known that although the domestic reserves of lithium ion ore are very abundant, the raw materials required for lithium iron phosphate batteries are synthetic materials, and the processing equipment and processes of domestic suppliers cannot keep up. Good lithium iron phosphate battery manufacturers are from Imported raw materials from abroad. At present, the price of imported raw materials from abroad is more than 120,000 yuan per ton. Domestic raw materials are relatively cheap, only 70,000-90,000 yuan per ton, but the quality of the processed batteries is not as good as the former. 2. The actual data supports the large-scale use of a new product, and it has to go through at least three stages. The first is that there should be no problems in theory. Secondly, there must be data support of aging test. Third, it is necessary to try the live network according to the time and scale. Theoretically, lithium iron phosphate batteries are safer and more reliable than lead-acid batteries, with a cycle charge and discharge life of up to 10 years, which can solve the latter's problems of high pollution and short life. However, in terms of the data of the aging test, the current lithium iron phosphate battery can not provide enough credible data support. As for live network applications, the longest trial period of lithium iron phosphate batteries in the communications industry is only about two years, and it is not yet possible to conclude that they can be used on a large scale. 3. Over-discharge of Lithium-Fe-Ion Battery Over-discharge of Li-Fe-Ion battery will not cause damage to the battery. The battery capacity will be restored after charging, and the current BMS of Li-Fe-Ion battery module has overcharge and over-discharge protection functions. However, if the iron-lithium-ion battery is over-discharged, the lagging battery in the battery pack module will be discharged to 0V first, and there is a possibility of battery polarity reversal. According to the manufacturer's inspection, the battery with reversed polarity will cause permanent damage. Therefore, BMS plays a very important role in iron-lithium-ion battery modules.
