Advantages and disadvantages of lithium iron phosphate batteries as UPS batteries

Lithium iron phosphate batteries have the disadvantages of UPS batteries. What are the advantages and disadvantages of lithium iron phosphate batteries? What are the technical shortcomings of lithium batteries as a backup power source for UPS batteries? Lithium iron phosphate batteries are used to make lithium ion secondary batteries, and the current important direction is power lithium ion batteries , But we also need to know the shortcomings of lithium iron phosphate batteries, we must pay attention to the process of use. The author will talk about the shortcomings and other aspects of the lithium iron phosphate battery as a UPS battery. Lithium iron phosphate battery: The so-called lithium iron phosphate battery refers to a lithium battery using lithium iron phosphate as the positive electrode material. Lithium battery cathode materials mainly include lithium cobalt acid, lithium manganese acid, lithium nickel acid, ternary materials, and lithium iron phosphate. At the same time, lithium cobalt oxide is the negative electrode material of most lithium batteries. Advantages of lithium iron phosphate battery as a UPS battery: 1. The life of lithium iron phosphate battery, the cycle life is more than 2000 times. Under the same conditions, lithium iron phosphate batteries can be used for 7-8 years. 2. Safe operation. Lithium iron phosphate batteries have passed strict safety inspections and will not explode even in traffic accidents. 3. Fast charging. Using a dedicated charger, the battery can be fully charged by charging at 1.5C for 40 minutes. 4. The lithium iron phosphate battery is resistant to high temperatures, and the hot air value of the lithium iron phosphate battery can reach 350 to 500 degrees Celsius. 5. Lithium iron phosphate battery has a large capacity, which is larger than that of ordinary batteries (lead-acid, etc.). 6. The lithium iron phosphate battery has no recall effect. No matter the battery is under any circumstances, it can be used with recharge, do not take it out and recharge it. 7. Lithium iron phosphate battery is environmentally friendly, non-toxic, non-polluting, in line with European RoHS regulations, and is a positive green battery. Disadvantages of lithium iron phosphate batteries as UPS batteries: 1. The vibration density of the positive electrode of lithium iron phosphate batteries is relatively small, generally between 0.8 and 1.3. 2. Poor conductivity, slow loosening of lithium ions, and lower actual specific capacity during high-power charging and discharging. 3. The low temperature performance of lithium iron phosphate battery is poor, the capacity drops rapidly when the temperature is lower than 0 degrees, and the low temperature cycle performance is extremely poor. 4. The life of lithium iron phosphate battery is longer, about 2000 times, while the life of lithium iron phosphate battery pack is shorter, generally about 500 times. 5. UPS batteries are expensive, process costs are high, and patent fees are expensive. 6. Large volume and large components. The same component is small in size and not suitable for small monomers. 7. Does not tolerate abuse. Compared with lead acid, the negative electrode material of lithium iron phosphate battery has poor conductivity and high internal resistance. The overcharge receiving capability is low, and the proposed function is far smaller than that of lead-acid batteries. 8. Poor product consistency. At present, there is no lithium iron phosphate material factory in my country that can solve this problem.
