What is the difference between lithium iron phosphate power lithium ion battery and lithium ion battery?

1. Lithium iron phosphate power lithium ion battery is made of positive electrode material LiFeCoPO4 olivine structure. Lithium iron phosphate power lithium ion battery is a kind of lithium metal material or lithium alloy as the battery cathode material, and non-aqueous solution is selected. Acid-alkaline rechargeable batteries; and ordinary lithium-ion batteries are mainly made of lithium manganate battery cathode materials. Spinel lithium manganate battery LiMn2O4 is a three-dimensional lithium-ion battery produced by Hunter for the first time in 1981 Battery cathode material for safe passage. However, along with the development trend of lithium-ion battery cathode materials, a large number of high-quality battery cathode materials are likely to 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 power lithium ion battery and lithium ion battery: The standard working voltage of the lithium iron phosphate power lithium ion battery service platform is, fill up the power, and the charge and discharge cut-off voltage of the lithium iron phosphate battery lithium cell is; Generally, the working voltage of the service platform of lithium-ion battery is, when the battery is fully charged, the charge-discharge cut-off voltage of the lithium battery is. In comparison, the working voltage of lithium-ion battery is higher than that of power lithium-ion battery; lithium iron phosphate battery is resistant to overcharge Over-discharge, the power loss can be repaired to more than 80% after a short period of time; when the lithium-ion battery is overcharged and discharged, irreversible damage will occur. 3. Lithium iron phosphate powered lithium ion battery will not explode if punctured. Generally, lithium ion battery will explode if punctured. 4. Lithium iron phosphate power lithium ion battery is not easy to explode if it is overcharged to 100%; general lithium ion battery reaches the standard value will release vapor surging. 5. The difference between the charge and discharge characteristics of lithium iron phosphate power lithium ion batteries and lithium ion batteries: lithium iron phosphate power lithium ion batteries can be applied to a continuous 30C charge and discharge speed without safety risks. Some rechargeable lithium iron phosphate batteries can achieve 600A instantaneous current, while the general lithium-ion battery is suitable for 3C charging and discharging speed under normal conditions, which will cause the rechargeable battery to die. 6. The net weight difference between lithium iron phosphate power lithium ion battery and lithium ion battery: the net weight of the same volume of lithium iron phosphate power lithium ion battery is basically twice that of ordinary lithium ion batteries. 7. The difference in internal resistance between lithium iron phosphate power lithium-ion batteries and lithium-ion batteries: The internal resistance of lithium iron phosphate power lithium-ion batteries with the same volume is much smaller than that of ordinary lithium-ion batteries. 8. The volume difference between lithium iron phosphate power lithium ion battery and lithium ion battery: the volume of the same volume of lithium iron phosphate power lithium ion battery is smaller than that of ordinary lithium ion batteries, that is, the specific energy ratio of rechargeable batteries made of lithium iron phosphate lithium ion battery cathode materials Generally, lithium-ion batteries are about 60% lower. 9. The price difference between lithium iron phosphate power lithium ion battery and lithium ion battery: the price of lithium iron phosphate power lithium ion battery is about 50% more expensive than general lithium ion batteries. 10. The working temperature difference between lithium iron phosphate power lithium ion battery and lithium ion battery: the operating temperature of lithium iron phosphate power lithium ion battery is higher than that of lithium ion battery, and the operating temperature of lithium ion battery is 6 degrees lower than that of lithium ion battery. . Generally, lithium-ion batteries do not contain metallic lithium. When charging, lithium ions are extracted from the positive electrode lattice under the drive of an electric field, pass through the electrolyte, and are inserted into the negative electrode lattice. When discharging, the process is just the opposite. Lithium ions return to the positive electrode, and the electrons pass through the electrical appliances and reach the positive electrode from the external circuit to recombine with the lithium ions. Since lithium-ion batteries do not contain any precious metals, the raw materials are very cheap, and there is a lot of room for price reduction, so it should be the cheapest battery. The disadvantage is safety. Due to the good tightness of the metal casing, the battery may generate a hidden danger of explosion when it heats up during use. Li-polymer batteries (Li-polymer) are based on lithium-ion batteries with polymer electrolytes instead of traditional liquid organic electrolytes. This polymer electrolyte can be used as an ion-conducting medium and as an isolation membrane. In addition, the reactivity with metal lithium is extremely low, so it effectively prevents the easy burning and easy leakage of lithium-ion batteries. And because the lithium ion polymer battery absorbs the liquid organic electrolyte on a polymer matrix, it is called a colloidal electrolyte. This electrolyte is neither a free electrolyte nor a solid electrolyte, which makes the lithium-lithium polymer battery not only The excellent performance of liquid lithium-ion batteries can also be made into ultra-thin products of any shape and size, making it widely applicable and promising for development. In addition, the safety is better than that of lithium-ion batteries. If they heat up during use, they will only swell or burn without exploding. Lithium iron phosphate battery refers to a lithium ion battery that uses lithium iron phosphate as a positive electrode material. The cycle life of a long-life lead-acid battery is about 300 times, and the highest is 500 times for a lithium iron phosphate battery, while a lithium iron phosphate power lithium battery has a cycle life of more than 2000 times. Standard charging (5 hours rate) can reach 2000 times. Lead-acid batteries of the same quality are new for half a year, old for half a year, and for maintenance and maintenance for half a year, at most 1 to 1.5 years, while lithium iron phosphate batteries will be used for 7 to 8 years under the same conditions. Comprehensive consideration, the performance-price ratio will be more than 4 times that of lead-acid batteries.
