Pacific Automotive Network utilizes the same battery structure, respectively selects ternary material and lithium iron phosphate material to make the battery, and conducts discharge, charging and cycling tests under different conditions, the ternary material has an advantage in the charging multiplier, discharging multiplier, and the discharge performance at different temperatures, while the lithium iron phosphate material is better in terms of cycling performance, and it is still able to maintain more than 80% of the initial capacity after 5000 times of 1C cycling.
Understanding the difference between lithium iron phosphate batteries and lithium ion batteriesLithium iron phosphate batteriesIntroductionLithium iron phosphate batteries are lithium ion batteries with lithium iron phosphate as the positive electrode. The cathode data of lithium ion batteries are important lithium cobalt oxide, lithium manganese oxide, lithium nickel oxide, ternary data, lithium iron phosphate and so on. Lithium cobalt oxide is the anode material for most lithium ion batteries.
Advantages of lithium iron phosphate batteries:
1. The lithium iron phosphate battery has a long lifespan, with a cycle life of more than 2000 times. Under the same conditions, lithium iron phosphate ion batteries can be used for 7-8 years.
2. Safety in use. Lithium iron phosphate batteries have passed rigorous safety tests and are unlikely to explode even in traffic accidents.
3. Fast charging. Using a special charger, the battery will overflow after 40 minutes of charging at a temperature of 1.5c.
4.Lithium iron phosphate ion batteries are resistant to high temperatures, lithium iron phosphate ion batteries have a hot wind value of 350~500°C.
5.Lithium iron phosphate ion batteries have a large capacity.
6. Lithium iron phosphate ion battery has no memory effect.
7. Iron phosphate lithium ion batteries are green, non-toxic, non-polluting, with a wide range of original sources and low prices.
Defects of lithium iron phosphate ion batteries
1.The positive electrode vibration density of lithium iron phosphate ion batteries is small, generally between 0.8 and 1.3. Large volume.
2. Poor electrical conductivity, lithium ion diffusion is slow, and the actual capacity is low during high-power charging and discharging.
3. Poor low temperature performance of lithium iron phosphate ion batteries.
4. The battery life of lithium iron phosphate ion batteries is longer, about 2,000 times, while the battery life of lithium iron phosphate ion batteries is shorter, about 500 times.
Lithium iron phosphate ion batteries application areas of large electric vehicles: buses, electric cars, tourist cars, hybrid cars; light electric vehicles: electric bicycles, golf carts, small flat battery cars, forklifts, janitorial carts, electric wheelchairs, etc.; electric tools: drills, saws, lawnmowers, etc..
Remote control of toys such as cars, boats, airplanes, etc.; energy storage devices for solar and wind power generation; UPS, emergency lights, warning lights, mining lamps (optimal safety); instead of 3V disposable lithium-ion batteries and 9V nickel-cadmium or nickel-metal hydride rechargeable batteries (of the same size) in the camera; small medical equipment and portable devices.
Lithium-ion BatteriesIntroductionLithium-ion batteries are batteries that use lithium metal or lithium alloy as the anode material and a non-aqueous electrolyte solution as the electrolyte. Because of the chemical properties of lithium metal is very active, so the processing, preservation and use of lithium metal, the environmental requirements are very high. Therefore, lithium-ion batteries have not been used for a long time. With the development of science and technology, lithium-ion batteries have become mainstream.
