For radio enthusiasts nowadays, one of the changes brought about by technological advances is that they are gradually replaced by lightweight lithium iron phosphate batteries. New technology applications require enthusiasts to have a new understanding of them.
Lithium iron phosphate batteries are popular with many enthusiasts because of their lighter weight under the same capacity, but this does not mean that traditional lithium iron phosphate batteries can be discarded and replaced by lithium iron phosphate batteries. Nowadays, there is no battery that can meet the needs of all applications.
Lithium phosphate batteries were invented in the second half of the 1990s. Like many other inventions, it took several years for these batteries to become inexpensive and practical. This compound is very stable, but usually the intrinsic internal resistance is too large. People use good conductors, such as graphite, to encapsulate compounds to reduce the internal resistance.
This kind of battery has many advantages, the biggest advantage for radio enthusiasts is the stable discharge voltage. The discharge voltage of traditional batteries is very high when they are fully charged, and then gradually decreases with the discharge process. The voltage of lithium iron phosphate battery hardly changes with the discharge process.
Lithium iron phosphate is a very stable compound, which makes this battery much safer than lithium battery. There are often stories of lithium battery explosions, and in many cases it burns itself without moving anything there. This phenomenon is commonly referred to as thermal runaway. Lithium iron phosphate batteries will not run out of heat. If you want this battery to burn, you have to destroy it carelessly or intentionally.
As for the hazards in general, there must be some pollution, but the pollution is relatively small compared with lead-acid batteries, because it does not use heavy metals and belongs to light pollution industrial projects, but attention should also be paid to the following aspects in production:
1. Powder material is non-toxic, but inhalation protection should be done well.
2. SBR has certain toxicity to prevent inhalation; NMP has slight toxicity, but has no obvious effect. It is necessary to do a good job to prevent strong corrosiveness in contact with the body.
3. Electrolyte has certain toxicity to prevent excessive inhalation and corrosiveness.
