How long is the true life of the lithium iron phosphate battery?

1. Lithium iron phosphate battery is used under normal temperature environment (1) The use of low current charging and discharging is basically used in 3C electronic products. If the lithium iron phosphate battery is used normally in this category, if it is Battery brand manufacturers are relatively strong, with good quality, and basically have a cycle life of more than 2000 times; small lithium battery manufacturers have a cycle life of more than 1000 times; (2) high-rate stable charging and discharging, high use The use of rate discharge is mostly power-type lithium batteries, and most of them are used to supply power to motors, such as new energy vehicles, electric vehicles, and fishing boat electromechanical power supplies. Since most of the lithium iron phosphate batteries are operated under high load conditions, the decay time of battery materials is accelerated, and the cycle life is sharply reduced. Poor quality batteries may have about 500 cycles; strong lithium iron phosphate battery brands Manufacturers will be better in the use of equipment technology and materials, and the quality of the cells will be better, but the cycle life will be about 800 times. (3) The lithium iron phosphate battery used in this case will have a shorter lifespan, and it will be scrapped after 300 times. The unstable discharge of the battery, which is high and sometimes low, will promote the use of the battery attenuation will be greater. 2. The high temperature performance of lithium iron phosphate battery used in high temperature environment is not very mature. The operating temperature is -20℃ to 125℃. This temperature range is theoretical value, and the actual temperature range is smaller. (1) If the lithium iron phosphate battery is used normally in this area for low-current charging and discharging, if the battery brand manufacturer is relatively strong and of good quality, it will basically have a cycle life of more than 1,000 times; small lithium battery manufacturers, The lower quality ones also have a cycle life of more than 500 times; because the battery is used at high temperature, the damage to the battery is relatively large. (2) High-rate stable charging and discharging The use of high-rate discharge of the battery in a high-temperature environment, most of which are power-type lithium batteries, and most of them are used to power the motor. The batteries are processed by strong domestic lithium battery manufacturers. It is mostly used in new energy vehicles, electric vehicles, fishing boat electromechanical power supplies, etc. Battery manufacturers with poor capabilities are mostly used in some relatively niche areas, such as medical treatment and boiler equipment startup. Since most lithium iron phosphate batteries are operated under high load conditions, the decay time of battery materials is accelerated, and the cycle life is sharply reduced. Poor quality batteries may only have about 300 cycles; strong battery brand manufacturers The equipment technology and materials will be better, and the quality of the cells will be better, but the cycle life will be about 500 times. (3) High-rate and unstable charging and discharging use high temperature and discharge rate to run unstable, which will damage the battery more and have a relatively low cycle life. After testing the cells of several battery manufacturers, it is found that the battery is basically used after 250 to 300 times. Not anymore. 3. The use of lithium iron phosphate batteries in a low temperature environment has a greater impact on the performance of lithium iron phosphate batteries than high. According to the current market situation, lithium iron phosphate batteries work under -20°C to -40°C. , Life is clearly reduced, the discharge current range is 0.2C to 1C, the discharge capacity is 50% to 60%, and the temperature is lower, the worse the discharge capacity. Therefore, there are not many low-temperature lithium iron phosphate batteries that are maturely used in the market today, with a temperature range of -20°C to 55°C, and a cycle life of about 300 times.
