Know the difference between lithium iron phosphate battery and lithium battery Introduction to lithium iron phosphate battery Lithium iron phosphate battery refers to a lithium battery with lithium iron phosphate as the positive electrode. The positive data of lithium batteries mainly include lithium cobalt acid, lithium manganese acid, lithium nickel acid, ternary data, and lithium iron phosphate. Lithium cobalt oxide is the anode material for most lithium batteries. Advantages of lithium iron phosphate batteries 1. Lithium iron phosphate batteries have a long life, with a cycle life of more than 2000 times. Under the same conditions, lithium iron phosphate batteries can be used for 7-8 years. 2. Safe to use. Lithium iron phosphate batteries have passed strict safety tests and are unlikely to explode even in traffic accidents. 3. Fast charging. Use a dedicated charger and charge it for 40 minutes at a temperature of 1.5c, and the battery will overflow. 4. The lithium iron phosphate battery is resistant to high temperature, and the hot air value of the lithium iron phosphate battery can reach 350~500℃. 5. The lithium iron phosphate battery has a large capacity. 6. The lithium iron phosphate battery has no memory effect. 7. Lithium iron phosphate battery is environmentally friendly, non-toxic, non-polluting, with a wide range of original sources and low price. Defects of lithium iron phosphate batteries 1. The vibration density of the positive electrode of lithium iron phosphate batteries is relatively small, generally between 0.8 and 1.3. Large volume. 2. Poor conductivity, slow diffusion of lithium ions, and low actual capacity during high-power charging and discharging. 3. The low temperature performance of lithium iron phosphate battery is poor. 4. The battery life of the lithium iron phosphate battery is longer, about 2000 times, while the battery life of the lithium iron phosphate battery is shorter, about 500 times. Application areas of lithium iron phosphate batteriesLarge electric vehicles: buses, electric vehicles, tourist cars, hybrid vehicles; light electric vehicles: electric bicycles, golf carts, small flat battery cars, forklifts, cleaning vehicles, electric wheelchairs, etc.; electric tools : Electric drills, saws, lawn mowers, etc. Remote control of toys such as cars, ships, airplanes; energy storage equipment for solar and wind power generation; UPS, emergency lights, warning lights, miner's lamps (best safety); instead of 3V disposable lithium batteries and 9V nickel-cadmium or nickel in the camera Hydrogen rechargeable battery (same size); small medical equipment and portable equipment. Introduction to Lithium Battery Lithium battery is a battery that uses lithium metal or lithium alloy as negative electrode material and non-aqueous electrolyte solution as electrolyte. Because the chemical properties of metal lithium are very active, the production, storage, and use of metal lithium have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have become the mainstream. Advantages of lithium batteries 1. High energy. With high energy storage density, it has reached 460-600wh/kg, which is about 6-7 times that of lead-acid batteries; 2. Long service life, service life up to more than 6 years, 1C (100% DOD) lithium iron phosphate positive battery ) Charge and discharge, it can be used 10,000 times; 3. The rated voltage is high (single working voltage is 3.7v or 3.2v), which is approximately equal to the series voltage of 3 nickel-cadmium or nickel-metal hydride rechargeable batteries, which is conducive to the formation of battery power packs; The lithium battery can adjust the voltage to 3.0v, suitable for small household appliances, through the skills of a new lithium battery regulator. 4. With high power tolerance, the lithium iron phosphate battery used in electric vehicles can reach 15-30c charge and discharge capacity, which is convenient for high-intensity startup and acceleration; 5. The self-discharge rate is very low, which is one of the most prominent advantages of the battery. Generally, it can reach 1%/month, which is less than 1/20 of Ni-MH battery; 6. Light weight, about 1/6-1/5 of the volume of lead-acid products; 7. High and low temperature adaptability, which can be in -20 It can be used in an environment of ℃ to 60℃, through process treatment, it can be used in an environment of -45℃; 8. Green and environmental protection, regardless of processing, use and waste, no lead, mercury, cadmium and other toxic and harmful heavy metal elements and substance. 9. No water is used for processing, which is very beneficial for my country's water shortage. Specific energy refers to the energy per unit component or unit volume. Specific energy is expressed in Wh/kg or Wh/L. Wh is a unit of energy, W is a watt, h is an hour; Kg is a kilogram (a unit of weight), and L is a unit of a liter (a unit of volume). The difference between lithium iron phosphate battery and lithium battery Defects of lithium battery 1. The safety of lithium primary battery is poor and there is a danger of explosion. Lithium cobalt oxide batteries cannot discharge large currents, are expensive, and have poor safety. 3. The circuit of lithium batteries should be maintained to prevent overcharging and discharging of the battery. 4. High processing requirements and high cost. 5. The use conditions are limited, and the use of high temperature and low temperature is dangerous. The application of lithium battery is the first, traffic power supply II. Energy storage power supply 3. Mobile communication power supply New energy storage power supply 5. Aerospace military power supply The difference between lithium iron phosphate battery and lithium battery Lithium iron phosphate battery and lithium battery Lithium iron phosphate battery and lithium battery are different. 1. Lithium iron phosphate batteries are used to manufacture lithium ion secondary batteries. The current important direction is power lithium-ion batteries, which have great advantages over nickel-hydrogen batteries and nickel-cadmium batteries. 2. Lithium battery is a battery with lithium metal or lithium alloy as the positive electrode and non-aqueous electrolyte solution. The chemical properties of lithium metal are very active, which makes the production, storage and application of lithium metal very demanding on the environment. 3. Lithium iron phosphate puncture will not catch fire or explode, and the lithium battery will explode. 4. Lithium iron phosphate will not explode when overcharged to 100%; the lithium battery will be inflated when it reaches the required value.
