The difference between lithium iron phosphate battery and lithium ion battery

1. The key of the lithium iron phosphate battery is made of the positive electrode material lithium iron phosphate LiFeCoPO4 olivine structure. The lithium iron phosphate battery is a kind of lithium metal material or lithium alloy as the battery cathode material, and the non-aqueous acid-alkaline rechargeable battery is selected. ; Ordinary lithium ion 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 safe channels produced by Hunter for the first time in 1981. . However, with the development trend of lithium-ion battery cathode materials, it is very likely that a large number of high-quality battery cathode materials will replace the current raw materials, but the safe use of lithium-ion battery materials is of paramount importance. 2. The working voltage difference between lithium iron phosphate battery and lithium ion battery: The standard working voltage of the lithium iron phosphate battery service platform is, fill up the power, and the charge and discharge cut-off voltage of the lithium iron phosphate battery lithium battery; general lithium ion battery service The working voltage of the platform is, when the battery is fully charged, the charging and discharging cut-off voltage of the lithium battery is. In comparison, the working voltage of the lithium-ion battery is higher than that of the power lithium-ion battery; the lithium iron phosphate battery is resistant to overcharge and overdischarge, and short-term loss After being charged to 0, more than 80% can be repaired; when the lithium-ion battery is overcharged and discharged, irreversible damage will occur. 3. If a lithium iron phosphate battery is punctured, it will not fire and will not explode. Generally, a lithium-ion battery will explode if it is punctured. 4. Lithium iron phosphate battery is not easy to explode if it is overcharged to 100%; general lithium-ion battery will release vapor surging if it reaches the standard value. 5. The difference between the charge and discharge characteristics of lithium iron phosphate batteries and lithium ion batteries: Lithium iron phosphate batteries can be applied to a continuous 30C charge and discharge speed without safety risks. Some lithium iron phosphate battery rechargeable batteries can achieve 600A instantaneous current, while the general lithium-ion battery is suitable for 3C charge and discharge speed under normal conditions, which will cause the rechargeable battery to die. 6. The difference in net weight between lithium iron phosphate batteries and lithium ion batteries: the net weight of lithium iron phosphate power lithium ion batteries with the same volume is basically twice that of ordinary lithium ion batteries. 7. The difference in internal resistance between lithium iron phosphate batteries and lithium-ion batteries: The internal resistance of lithium iron phosphate batteries with the same volume is much smaller than that of ordinary lithium-ion batteries. 8. The volume difference between lithium iron phosphate battery and lithium ion battery: the volume of the same volume of lithium iron phosphate battery is smaller than that of ordinary lithium ion batteries, that is, the rechargeable battery made of lithium iron phosphate battery cathode material has 60% lower energy than ordinary lithium ion batteries. up and down. 9. The price difference between lithium iron phosphate batteries and lithium ion batteries: the price of lithium iron phosphate batteries is about 50% more expensive than ordinary lithium ion batteries. 10. The working temperature difference between lithium iron phosphate battery and lithium ion battery: the operating temperature of lithium iron phosphate battery is higher than that of lithium ion battery, while the operating temperature of lithium ion battery is 6 degrees lower than that of lithium ion battery.
