Simple analysis of 32650 lithium iron phosphate battery

The 32650 lithium iron phosphate battery has a diameter of 32MM and a length (height) of 65/70. The positive electrode uses lithium iron phosphate as the positive electrode material, the rated voltage is 3.2V, and the overflow voltage is 3.6V. The capacity ranges from 4500mAh to 6500mAh. It has the advantages of higher energy density, good safety performance, long cycle life, environmental protection and pollution-free. According to reports, the energy density of the square aluminum-shell lithium iron phosphate batteries mass-produced in 2018 is about 160Wh/kg. In 2019, some excellent battery manufacturers can probably achieve the level of 175-180Wh/kg. Some powerful manufacturers use stacks. The film technology and capacity can be made larger, or 185Wh/kg can be achieved. The electrochemical performance of the 32650 lithium battery cathode material is relatively stable, which determines that it has a stable charging and discharging platform. Therefore, the structure of the battery will not change during the charging and discharging process, and it will not burn and explode, and even in short circuit or overcharge It is still very safe under special conditions such as squeezing and acupuncture. The 1C cycle life of 32650 lithium iron phosphate batteries generally reaches 2000 times, or even more than 3,500 times, and the energy storage market requires 4000-5000 times or more, guaranteeing a service life of 8-10 years, which is higher than the ternary battery more than 1,000 times Cycle life, while the cycle life of long-life lead-acid batteries is about 300 times. The 32650 lithium iron phosphate battery does not contain any heavy metals and rare metals, is safe, non-toxic and pollution-free, and is an absolute green battery. As the lithium iron phosphate material is clean and non-toxic during the entire processing process, all raw materials are non-toxic and non-polluting. 32650 lithium iron phosphate batteries are widely used in large electric vehicles (such as electric buses, electric trucks, sightseeing cars, etc.). Light electric vehicles: (such as electric bicycles, golf carts, small flat battery vehicles, forklifts, cleaning vehicles, electric Wheelchairs, etc.) UPS, outdoor mobile power supplies, emergency lights, miners’ lamps, solar energy storage, etc. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
