Lithium iron phosphate batteries are good.
1. Different Voltages:The rated voltage is 3.2V for lithium iron phosphate batteries and 3.7V for lithium polymer batteries.
2. Different Capacity: The capacity of lithium polymer battery is much larger with the same volume; for example, the 18650 lithium polymer battery has a capacity of 2200 mAh, while the lithium polymer battery has a capacity of 2200 mAh. the iron phosphate battery has a capacity of 1100 mAh, and the lithium iron phosphate battery can recover after being discharged to a voltage of 0V, although the over-discharge protection voltage is generally 2V while that the over-discharge protection voltage of lithium polymer batteries is 2.7; V, if it is lower, it will break.
3. The discharge current isdifferent:The power lithium polymer battery has a maximum discharge current of 5 times, and the lithium iron phosphate battery can discharge a current of 10 times; the same goes for charging, so lithium iron phosphate battery can be charged faster.
The Pacific Automotive Network lithium iron phosphate battery cannot be used when its capacity is attenuated by 50%. The capacity of the lithium iron phosphate battery at -10°C is attenuated to approximately 50%. %, and the maximum cannot exceed - Operates at 20°C. The lower limit of ternary lithium is -30°C, and the attenuation degree at the same temperature is lower than that of lithium iron phosphate.
The performance of lithium iron phosphate batteries is worse than that of ternary lithium batteries at low temperatures. The capacity of the lithium iron phosphate battery decreases to approximately 50% at -10°C and it cannotDo not operate above -20°C. The lower limit of ternary lithium is -30°C, and the attenuation degree at the same temperature is lower than that of lithium iron phosphate. It's no wonder that ternary batteries have become common. During the Northeast winter, -10 degrees Celsius is common and ternary lithium batteries are no good either. The battery dims 30% at -10 degrees, and better batteries should be developed.
What is a lithium iron phosphate battery?
Lithium iron phosphate battery is a type of lithium ion battery, which refers to a lithium ion battery using lithium iron phosphate as the positive electrode material. It features high safety and stability, high temperature resistance and good cycle performance.
The lifespan of lithium iron phosphate batteries is the same as that of bed batteriesternary hium. The theoretical lifespan of lithium iron phosphate batteries also exceeds 2,000 charge and discharge cycles. Even if they are charged once a day, they are charged. can last more than five years. Generally speaking, daily home use requires three days of charging, which can last around eight years. However, due to the poor low temperature performance of lithium iron phosphate batteries, the service life of lithium iron phosphate batteries will be relatively longer in the southern region.
At the same time, the battery life of new energy vehicles is also related to the owner's charging and discharging depth and the frequency of aggressive driving. Of course, there is also the most important technical factor: the battery management system.
