What factors affect the service life of lithium iron phosphate batteries?

What are the effects on the service life of lithium iron phosphate batteries? What is the impact on the service life of lithium iron phosphate batteries? The lithium iron phosphate battery mentioned in this article is one of the more common lithium battery UPSs. Because lithium iron phosphate batteries are made of lithium iron phosphate cathode materials, compared with other types of lithium batteries, the price is relatively cheap, and it is environmentally friendly and pollution-free, and has high safety and stability. Based on the above reasons, the application of lithium iron phosphate batteries is widely planned. Since we are familiar with lithium iron phosphate batteries, we will naturally pay attention to all aspects of it. Today let us talk about the service life of lithium iron phosphate batteries. 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. Lithium cobalt oxide is the negative electrode material for most lithium batteries. After 5000 cycles of recycling lithium iron phosphate batteries, the capacity of the lithium iron phosphate batteries reached 84%, and the 1C cycle life of the lithium iron phosphate battery laboratory reached more than 3500 times, and some reached more than 5000 times. Factors affecting the service life of lithium iron phosphate batteries. When choosing a charger, it is best to use a charger with correct terminal charging equipment (such as reverse overcharge time equipment, negative voltage difference (-dv) to cut off charging and reverse Overheating induction equipment) to prevent lithium iron phosphate batteries from shortening their service life due to overcharging. Generally speaking, slow charging can extend battery life better than fast charging. Depth of discharge is an important factor affecting the life of lithium iron phosphate batteries. The higher the depth of discharge, the shorter the life of the lithium iron phosphate battery. In other words, as long as the depth of discharge is reduced, the service life of the lithium iron phosphate battery can be greatly extended. Therefore, we should prevent the extremely low voltage of lithium battery UPS from over-discharge. Lithium iron phosphate batteries have different capacities, chemical structures or different charging levels, and the mixed use of new and old batteries will also cause excessive discharge of lithium iron phosphate batteries, and even reverse charging. If the lithium iron phosphate battery is not charged for a long time, its life will be reduced. Lithium iron phosphate batteries need a long period of electron flow to reach the expected service life. II. Operating environment If a lithium iron phosphate battery is used at high temperature for a long period of time, it will attenuate the electrode activity and shorten the service life. Therefore, maintaining an appropriate working temperature as much as possible is a good way to expand the lithium iron phosphate battery. life. Prevent dust accumulation in the box and maintain the battery in the power supply in time. Battery maintenance is also an important point to extend battery life. Dust accumulation is caused by static electricity caused by battery operation to attract dust. Dust accumulation will prevent the operation of components. Therefore, it is important to clean the dust to ensure a good operating environment for lithium iron phosphate batteries. . Experimental results show that with the increase in the number of recharges, the life of the lithium iron phosphate battery continues to decline. In general, the number of recharges for lithium iron phosphate batteries is 3000-5000 times. In order to measure the performance of rechargeable batteries, we mean the number of cycles. The user's practice is diverse, because experiments under different conditions are not comparable. To compare, the life cycle must be standardized. The service life number of lithium iron phosphate batteries can generally be obtained from the theoretical life number on the label, but the actual service life number is generally different from the theoretical life number, and the use habits are prominent, which makes our battery life longer.
