Lithium iron phosphate power lithium battery is mainly made of olivine structure of lithium iron phosphate LiFePO4;Ordinary lithium batteries are mainly made of lithium manganate battery cathode materials.

Difference between LiFePO4 battery and lithium battery

1. Lithium iron phosphate power lithium battery is mainly made of olivine structure of lithium iron phosphate lifecopo4, the cathode material. Lithium iron phosphate power lithium battery is a non-aqueous acid-base rechargeable battery with lithium metal material or lithium alloy as the cathode material; Ordinary lithium batteries are mainly made of lithium manganate battery cathode materials. Spinel lithium manganate battery LiMn2O4 is a battery cathode material with three-dimensional lithium ion battery safety channel first manufactured by hunter in 1981. However, with the development trend of lithium battery cathode materials, it is likely that a large number of high-quality battery cathode materials will replace the current raw materials, but anyway, the safe application of lithium battery materials is very important.

2. Working voltage difference between lithium iron phosphate power battery and lithium battery: the standard working voltage of lithium iron phosphate power battery service platform is, filled with power, and the cut-off voltage of lithium iron phosphate battery is; Generally, the working voltage of the service platform of lithium battery is. When the battery is fully charged, the cut-off voltage of lithium battery cell is. In contrast, the working voltage of lithium battery is higher than that of power lithium battery; Lithium iron phosphate battery can withstand overcharge and discharge, and can repair more than 80% after power loss reaches 0 in a short time; Lithium ion battery will cause irreversible damage when it is overcharged and discharged.


3. Lithium iron phosphate power lithium battery will not catch fire or explode if punctured. Generally, lithium battery will explode if punctured.


4. Lithium iron phosphate power lithium battery is not easy to explode when overcharged 100%; Generally, the standard value of lithium battery will release steam surge.

5. Difference in charge and discharge characteristics between lithium iron phosphate power battery and lithium battery: lithium iron phosphate power battery can be applied to continuous 30C charge and discharge speed without safety risk. Some lithium iron phosphate rechargeable batteries can achieve 600A instantaneous current, while the general lithium battery is applicable to 3C charge and discharge speed under all normal conditions, which will lead to the death of the rechargeable battery.

6. Difference in net weight between lithium iron phosphate power battery and lithium battery: the net weight of lithium iron phosphate power battery with the same volume is basically twice that of ordinary lithium battery.

7. Difference in internal resistance between lithium iron phosphate power battery and lithium battery: the internal resistance of lithium iron phosphate power battery with the same volume is much smaller than that of ordinary lithium battery.

8. Volume difference between lithium iron phosphate power battery and lithium battery: the volume of lithium iron phosphate power battery with the same volume is smaller than that of ordinary lithium battery, that is, the specific energy of rechargeable battery made of lithium iron phosphate battery cathode material is about 60% lower than that of ordinary lithium battery.

9. Price difference between lithium iron phosphate power battery and lithium battery: the price of lithium iron phosphate power battery is about 50% higher than that of general lithium battery.

10. Temperature difference between lithium iron phosphate power battery and lithium battery: the operating temperature of lithium iron phosphate power battery is higher than that of lithium battery, and the operating temperature of lithium battery is about 6 degrees lower than that of lithium battery.
