Introduction to the storage conditions of lithium-ion batteries

Storage conditions of lithium-ion batteries Lithium-ion batteries were invented in the second half of the 1990s. Like many other inventions, it takes two years for rechargeable batteries to get better. This chemical substance is very stable, but generally the inherent internal resistance is too large. We use high-purity graphite capsules and other good-conducting chemicals to reduce the internal resistance. Lithium-ion batteries have many advantages, the most important of which is the stable discharge voltage. A traditional battery will discharge at a very high voltage when it is fully charged, and then gradually decrease when it is discharged. The voltage of the lithium iron phosphate battery does not change much with the discharge process. So what are its advantages? High-temperature performance lithium-ion batteries can reach a maximum temperature of 350 ℃-500 ℃, while the maximum temperature of lithium manganese oxide and lithium cobalt oxide is only about 200 ℃. The operating temperature range is wide (-20c75C), and the high temperature resistant lithium iron phosphate can reach a maximum temperature of 350℃-500℃, while lithium manganese and lithium cobalt acid are only about 200℃. Large capacity and light weight When the battery continues to run at full load, it will quickly drop below the rated capacity. This phenomenon is called the memory effect. Like nickel-metal hydride batteries and nickel-cadmium batteries have memory, but lithium iron phosphate batteries do not have this phenomenon. No matter what state the battery is in, it can be charged and used at any time without having to turn it off before charging. The volume of a lithium iron phosphate battery with the same capacity is 2/3 of that of a lead-acid battery, and its weight is 1/3 of that of a lead-acid battery. Life improvement lithium-ion battery wholesale lead-acid battery cycle life is about 300 times, the highest is about 500 times, while the cycle life of lithium ion batteries is more than 2000 times, using standard charging (5 hours rate), it can reach about 2000 times.
