What are the differences between lithium iron phosphate lithium ion power lithium ion battery and lithium ion battery?

1. Lithium iron phosphate power lithium ion battery is mainly made of olivine structure structure of lithium iron phosphate lithium ion LiFeCoPO4. Lithium iron phosphate power lithium ion battery is a kind of lithium ion metal material or lithium ion alloy as the battery cathode material. , Select non-aqueous acid-alkaline rechargeable batteries; and ordinary lithium-ion batteries are mainly made of lithium manganate battery cathode materials, spinel lithium manganate battery LiMn2O4 was first processed and manufactured by Hunter in 1981 A battery cathode material with a safe channel for three-dimensional lithium-ion batteries. However, along 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 lithium ion battery and lithium ion battery: The standard operating voltage of the lithium iron phosphate lithium ion power lithium ion battery service platform is, fill up the power, and charge and discharge the lithium iron phosphate lithium ion battery. The cut-off voltage is; the working voltage of the service platform of the general lithium-ion battery is, when the battery is full, the charge-discharge cut-off voltage of the lithium-ion battery is, in comparison, the working voltage of the lithium-ion battery is higher than that of the power lithium-ion battery; iron phosphate Lithium-ion batteries are resistant to overcharge and overdischarge, and can be repaired to more than 80% after a short period of time when the power is lost to zero; irreversible damage will occur when lithium-ion batteries are overcharged and discharged. 3. Lithium iron phosphate lithium ion battery will not fire and will not explode if punctured. Generally, lithium ion battery will explode if punctured. 4. Lithium iron phosphate lithium ion battery is not easy to explode if it is overcharged to 100%; generally, if the lithium ion battery reaches the standard value, it will release vapor swelling. 5. The difference between the charge and discharge characteristics of lithium iron phosphate lithium ion batteries and lithium ion batteries: lithium iron phosphate lithium ion batteries can be used for continuous 30C charge and discharge speeds, and there is no safety risk. 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 lithium ion battery and lithium ion battery: the net weight of the same volume of lithium iron phosphate 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 lithium ion battery and lithium ion battery: the volume of the same volume of lithium iron phosphate lithium ion power lithium ion battery is smaller than that of ordinary lithium ion batteries, that is, the ratio of rechargeable batteries made of lithium iron phosphate lithium ion battery cathode material Energy is about 60% lower than that of ordinary lithium-ion batteries. 9. The price difference between lithium iron phosphate lithium ion battery and lithium ion battery: the price of lithium iron phosphate lithium ion battery is about 50% more expensive than ordinary lithium ion batteries. 10. The working temperature difference between lithium iron phosphate lithium ion battery and lithium ion battery: the operating temperature of lithium iron phosphate lithium ion battery is higher than that of lithium ion battery, and the operating temperature of lithium ion battery is 6 lower than that of lithium ion battery. Degrees up and down. Generally, lithium-ion batteries do not contain metallic lithium ions. During charging, lithium is extracted from the positive electrode lattice under the drive of an electric field, passes through the electrolyte, and is inserted into the negative electrode lattice. When discharging, the process is just the opposite. Lithium returns to the positive electrode, and the electrons pass through the electrical appliances and reach the positive electrode from the external circuit to combine with lithium. 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-ion 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 ions is extremely low, so it effectively prevents the easy burning and easy leakage of lithium-ion batteries. And because the lithium 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 ion lithium ion sub-polymer battery not only With the excellent performance of liquid lithium-ion batteries, it 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 ions as a positive electrode material. The cycle life of long-life lead-acid batteries is about 300 times, and the highest is 500 times for lithium iron phosphate batteries, while lithium iron phosphate power lithium batteries have a cycle life of more than 2000 times. Standard charging (5 hours rate) can be used. Reached 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.
