What about lithium iron phosphate batteries?

For today's radio enthusiasts, one of the changes brought about by technological progress is the gradual replacement of portable lithium iron phosphate batteries. New technology applications require new understanding among enthusiasts.

lithium iron phosphate battery has gained a lot of fans because of its light weight under the same capacity, but this does not mean that the traditional lithium iron phosphate battery can be thrown away and replaced by lithium iron phosphate battery. Currently, there is no single battery that can meet the requirements of all applications.

Lithium phosphate batteries were invented in the late 1990s, and like many other inventions, they took years to become cheap and practical. This compound is very stable, but usually the intrinsic resistance is too high, and people use good conductors, such as graphite, to wrap the compound to reduce the internal resistance.

This kind of battery has many advantages, the biggest advantage for radio lovers is a more stable discharge voltage. Conventional batteries discharge at high voltages when fully charged, and then gradually lower as they discharge. The voltage of the lithium iron phosphate battery hardly changes with the process of discharge.

Lithium iron phosphate is a very stable compound, which makes it much safer than lithium batteries. There's a lot of news about lithium batteries exploding, and in many cases it just sits there and doesn't move, and it just burns. This phenomenon is commonly referred to as thermal runaway. Lithium iron phosphate batteries rarely lose their heat. To get it to burn, you have to be very careful or very deliberate about destroying it.

As for the overall harm, there is definitely some pollution, but compared with lead-acid batteries, the pollution is not large, because it does not use heavy metals, which is a light pollution industrial project. However, the following aspects should be paid attention to in the production:

1.powder material non-toxic, but need to do inhalation protection

2.SBR has certain toxicity, prevent inhalation; NMP is slightly toxic, but has no obvious effect, and it needs to be well prepared to prevent strong corrosion in contact with the body

3.the electrolyte has a certain toxicity, prevent excessive inhalation and corrosion.
