Advantages and disadvantages of lithium iron phosphate battery and "lithium battery"

The lithium phosphate battery refers to a lithium ion battery using lithium iron phosphate as a positive electrode material. The positive electrode material of the lithium-ion battery mainly has lithium cobalt organte, lithium manganate, lithium nickel acid, and lithium iron phosphate. Lithium cobaltate is a positive material currently used in most lithium ion batteries. I. Advantages of lithium iron phosphate battery 1. The lithium phosphate battery has a long life and a cycle life is more than 2,000 times. Under the same conditions, lithium iron phosphate batteries can use 7 to 8 years. 2, use safety. Lithium iron phosphate batteries have undergone strict safety tests even in traffic accidents. 3, fast charging. Using a dedicated charger, 1.5C charge 40 minutes to make the battery. 4, lithium iron phosphate battery high temperature resistance, iron phosphate battery thermal value can reach 350 to 500 degrees Celsius. 5, the amount of lithium iron phosphate battery is large. 6. There is no memory effect of lithium iron phosphate battery. 7, lithium iron phosphate battery green environmental protection, non-toxic, no pollution, extensive source of raw materials, cheap. Disadvantages of lithium iron phosphate battery 1. The positive vibration density of the lithium iron phosphate battery is small, and the density is generally about 0.8 to 1.3. huge size. 2, poor conductivity, slow dissipation speed, high-speed charging, the actual amount is low. 3, the low temperature performance of lithium iron phosphate battery. 4 Second, the application field of lithium iron phosphate battery Large electric vehicle: bus, electric forklift, AGV, energy storage, photovoltaic, electric car, attraction tour and hybrid vehicles, etc .; Light electric car: electric bicycle, golf cart, small flat battery car, forklift, cleaning car, electric wheelchair, etc .; Electric tools: electric drill, chainsaw, lawn mower, etc .; Remote control car, ship, aircraft and other toys; Solar energy and wind power energy storage equipment; UPS and emergency lights, warning lights and mine lights (best security); Instead of the disposable lithium battery of 3V in the camera and 9V nickel cadmium or nickel hydride rechargeable battery (identified); Small medical instruments and portable instruments, etc. Third, lithium iron phosphate battery and lithium battery difference Lithium battery introduction The lithium battery is a class of a battery having a no-water electrolyte solution using a lithium metal or lithium alloy. Since the chemical properties of lithium metal are very lively, the processing, preservation, and use of lithium metal is very high. Therefore, the lithium battery has not been applied for a long time. With the development of science and technology, the lithium battery now has become mainstream. Advantages of lithium batteries 1, the energy is relatively high. It has high storage energy densities, has reached 460-600Wh / kg, and is about 6-7 times the lead-acid battery; 2, long service life, can reach more than 6 years, phosphate is a positive battery 1C (100% DOD) charge and discharge, there is a 10,000 times records; 3, the rated voltage is high (single operating voltage is 3.7V or 3.2V), which is about 3 nickel-bad or nickel-hydrogen charging batteries, which is convenient to constitute a battery power supply group; lithium battery can pass through a new lithium battery The technique of the press is adjusted to 3.0V to suit the use of small electrical appliances; 4, with high power tolerance, where the phosphate lithium ion battery for electric vehicles can reach 15-30C charge and discharge, easy to start acceleration; 5, the self-discharge rate is very low, this is one of the most prominent superiority of the battery, generally 1% / month or less, less than 1/20 of the NiMH battery; 6, light weight, weight of the same volume of about 1/6-1 / 5; 7, high and low temperature adaptability, can be used in an environment of -20 ¡ã C - 60 ¡ã C, after processes, can be used at -45 ¡ã C; 8. Green environmental protection, no matter in production, use and scrap, it does not contain any lead, mercury, cadmium and other toxic and harmful metallic elements and substances. 9. Production is basically not consumed, and my country is very beneficial to China. Compared to energy refers to the energy of unit weight or unit volume. It is represented by WH / kg or WH / L than energy. The unit is the unit of energy, W is the watt, H is hour; kg is a kilogram (weight unit), L is a liter (volume unit). Disadvantages of lithium battery 1. The lithium-organized battery is poor, and there is a danger of explosion. 2. Lithium-ion batteries of lithium cobaltate cannot be large current discharge, and the price is expensive and poor safety. 3. The lithium ion battery needs to protect the line to prevent the battery from being overcharged. 4. The production requirement is high and the cost is high. 5. Use conditions are limited, and the high and low temperature is dangerous. Lithium battery application field First, traffic power supply Second, power storage power supply Third, mobile communication power Fourth, new energy storage power electricity Five, aerospace military power supply Fourth, lithium iron phosphate battery and lithium battery difference Be Lithium iron phosphate batteries and lithium batteries are different. 1, the lithium phosphate battery is used to do lithium ion secondary batteries, and now the main direction is a power battery, which has great advantages in the relative Ni-H, Ni-CD battery. 2, lithium battery is a class of a battery having a nonaqueous electrolyte solution using a lithium metal or lithium alloy as a positive electrode material using a nonaqueous electrolyte solution. The chemical properties of lithium metal are very lively, allowing lithium metal processing, preservation, use, very high environmental requirements. 3, lithium iron phosphate wear thorn does not afford the fire, the lithium battery will. 4, lithium iron phosphate is resistant to 100% will not fire explosion; the lithium battery will be paid to the specified val Recommend: LiFePO4 Battery Manufacturer Energy storage battery Manufacturer Integrated machine energy storage battery series Manufacturer Lead lithium battery Manufacturer Outdoor Backup Battery Manufacturer Portable outdoor power supply Manufacturer Power battery Manufacturer Powerwall LiFePO4 Battery Manufacturer Battery rack Manufacturers Telecom LiFePO4 Battery Manufacturer Wall mounted battery storage Manufacturer China Lifepo4 Battery
