Lithium Iron Phosphate Battery Life Is 4-5 Times Longer Than Lead-acid Batteries, And The Price Is Only Twice. Why Can't It Replace Lead-acid Batteries?

Lithium Iron Phosphate Battery Life Is 4-5 Times Longer Than Lead-acid Batteries, And The Price Is Only Twice. Why Can't It Replace Lead-acid Batteries?

In automotive start-up battery applications, the life of lead-acid batteries is about 3 years, and 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, the safety of lead-acid batteries is much higher than that of lithium iron phosphate batteries. Finally, the low temperature start of lithium iron phosphate has not been well resolved, thanks to Frei Liu. In terms of UPS applications, the market for lead-acid batteries has been eroded. Although small UPS uses lead-acid batteries in a clear manner, the proportion of large and medium-sized UPS lithium iron phosphate batteries is increasing. Since last year, China Mobile Netcom Telecom Communications Base Station has begun to use lithium iron phosphate batteries. As a base station UPS, the price advantage of lithium iron phosphate has been reflected, and the lithium iron phosphate battery has better tolerance to high temperature than lead-acid batteries, which can save temperature control costs. In the application 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 not good, and the battery capacity of dozens of kilometers is not attenuated. less. In terms of energy storage in power plants, lithium iron phosphate batteries have completely crushed lead-acid batteries, but at present there is no energy storage technology that can fully meet the grid-level requirements, and it can only be said that the big ones are big. Finally, the production of lithium iron phosphate is a patent dispute in foreign countries, which is one reason why foreign electric vehicles generally use ternary cathode material lithium batteries.
