Why can't lithium iron phosphate batteries replace lead-acid batteries?

First, let us talk about the scale of lead-acid batteries. Important markets for lead-acid batteries are car batteries, uninterruptible power supplies (UPS), electric bicycles, and power station storage. Taking car batteries as an example, the lifespan of lead-acid batteries is about 3 years, while the calendar life of lithium iron phosphate batteries is 5 years, so the price of lithium iron phosphate batteries is definitely a disadvantage. In addition, lead-acid batteries are much safer than lithium iron phosphate batteries. Finally, due to Freyliu's reminder, the low-temperature lithium iron phosphate engine is not being handled well now. In the case of UPS, the market for lead-acid batteries has been steadily eroded. Although lead-acid batteries are only used for small UPS, the proportion of large and medium-sized UPS lithium iron phosphate batteries is increasing. Since the beginning of last year, the batteries of my country Mobile and Netcom Telecom's communication base stations have now all started to use lithium iron phosphate batteries. As a base station using UPS, the price advantage of lithium iron phosphate has been reflected. The resistance of lithium iron phosphate batteries to high temperatures is better than that of lead-acid batteries, which can save the cost of temperature control. The use of electric bicycles, the price of lithium iron phosphate battery bicycles and the price of lead-acid battery bicycles are very different. The choice is in the hands of consumers, and the quality of bicycle batteries is uneven. The state of battery capacity degradation after tens of kilometers is not much . In terms of energy storage in power stations, lithium iron phosphate batteries have completely crushed lead-acid batteries, but currently they cannot fully meet the grid-level energy storage technology. It can only be said to be short-term. Finally, the processing of lithium iron phosphate has been patented abroad, which is one of the reasons why ternary cathode material lithium batteries are widely used in foreign electric vehicles. The lifespan of lithium iron phosphate batteries is not necessarily 4-5 times longer than that of lead-acid batteries. At present, the technical content of lead-acid batteries is relatively high, and the 5-year lifespan is no problem. However, due to the breakdown of the structure of the negative electrode material graphite, even if it is not used for five years, the lithium battery will be abandoned. Different quality batteries cannot be compared, and Nanfu and Dongfang are also far apart. Lithium batteries do not pollute the environment more than lead-acid batteries, but they are certainly not environmentally friendly.
