The evil is great. The lithium battery factory is divided into two parts:
If it manufactures battery cells, the elements inside the battery cells are harmful to the human body. It is not recommended to go there. mask or mask when working. Lithium-ion battery production is toxic. Because lithium batteries contain heavy metals such as mercury, they can penetrate the skin and enter the body's circulatory system if they come into contact with the skin.
If you are doing PACK, it has almost no impact on the body (some workstations must be exposed to organic solvents), you can consider it.

Lithium battery characteristics
1. High energy density
The weight of lithium-ion batteries is half that of nickel-cadmium batteries ou nickel-hydrogen of the same capacity, and the volume is 20-30% nickel-cadmium and 35-50% nickel-hydrogen.
2. High voltage
The operating voltage of a lithium-ion battery cell is 3.7 V (on average), which is equivalent to three connected nickel-cadmium or nickel-metal hydride batteries. serial.
3. Pollution-free
Lithium-ion batteries do not contain harmful metal substances such as cadmium, lead and mercury.
4. Does not contain lithium metal
Lithium-ion batteries do not contain lithium metal, so they are not restricted by air transport regulations such as the ban on transporting lithium batteries on board passengers. plane.
5. High service life
Under normal conditions, the charge and discharge cycles of lithium-ion batteries can exceed 500 times, and lithium iron phosphate (hereinaftercalled iron phosphate) can reach 2,000 of second order.
6. No memory effect
The memory effect refers to the phenomenon that the battery capacity decreases during the charge and discharge cycle of nickel-cadmium batteries. This effect does not exist with lithium-ion batteries.
7. Fast charging
Using a constant current and constant voltage charger with a rated voltage of 4.2V, the lithium-ion battery can be fully charged in 1.5-2.5 hours; and The new lithium iron phosphate battery can be fully charged in 35 minutes.
