Yes there is, lithium battery factories are divided into two major blocks:
If you are doing the core, the inside of the core is harmful to the human body, it is not recommended to go to work to bring gas masks or masks. Producing lithium-ion batteries is toxic. Because lithium batteries contain heavy metals such as mercury, contact with the skin may seep into the skin and enter the body's circulatory system.
If you are doing PACKs, which basically have no effect on your body (individual stations need to be exposed to organic solvents), you can consider going.
Lithium battery features
1, high energy density
Lithium-ion batteries are half the weight of nickel-cadmium or nickel-metal hydride batteries with the same capacity, and the volume is 20-30% of nickel-cadmium and 35-50% of nickel-metal hydride.
2, high voltage
A single lithium-ion battery has an operating voltage of 3.7V (average), which is equivalent to three series-connected nickel-cadmium or nickel-metal hydride batteries.
3, no pollution
Lithium-ion batteries do not contain such harmful metal substances as cadmium, lead, mercury.
4, does not contain lithium metal
Lithium-ion batteries do not contain lithium metal, and therefore are not subject to the restrictions of aircraft transportation on the prohibition of lithium batteries in passenger aircraft.
5, high cycle life
Under normal conditions, lithium-ion batteries can be charged and discharged more than 500 times, and lithium ferrous phosphate (hereinafter referred to as ferrophosphorus) can reach 2000 times.
