What about lithium iron phosphate batteries?

For current radio enthusiasts, one of the changes brought about by technological advances is that enthusiasts have gradually replaced with portable lithium iron phosphate batteries. The use of new technologies requires enthusiasts to have a new understanding of it. Lithium iron phosphate batteries are loved by many enthusiasts because of their lighter weight under the same capacity, but this does not mean that traditional lithium batteries can be thrown away. , Replaced with lithium iron phosphate battery. Under the current technical conditions, there is no battery that can meet all the needs of use. Phosphate lithium batteries were invented in the second half of the 1990s. Like many other inventions, it took several years for this battery to become cheap and practical. This compound is very stable, but the intrinsic internal resistance is usually too large, and people use good conductors such as graphite coated compounds to reduce the internal resistance. This kind of battery has many advantages, the biggest advantage for radio enthusiasts is the more stable discharge voltage. When the traditional battery is fully charged, the discharge voltage is very high, and then as the discharge process, the voltage gradually decreases. The voltage of the lithium iron phosphate battery hardly changes with the progress of the discharge. Lithium iron phosphate is a very stable compound, which makes this battery much safer than lithium batteries. There are often news of lithium battery explosions, and in many cases, it burns on its own when it is left there without moving anything. This phenomenon is generally called thermal runaway. Lithium iron phosphate batteries are basically not thermally runaway. To make this kind of battery burn, you have to destroy it carelessly or deliberately. As for the hazards in general, there is definitely pollution, but the pollution is not related to lead-acid batteries because it does not use heavy metals and belongs to light-polluting industrial projects. However, the following aspects should be paid attention to during processing: 1. No powder materials Toxic, but must be protected against inhalation 2. SBR has a certain toxicity, beware of inhalation; NMP is slightly toxic, but has no obvious effect, beware of strong corrosive contact with the body 3. Electrolyte has a certain toxicity , Beware of excessive inhalation and corrosiveness. Statement: Some pictures and content of articles published on this site are from the Internet.
