1. Lithium-ion battery is absolutely harmful to human body. The most harmful is electrolyte solution, which is an organic volatile liquid with obvious corrosiveness. Long-term inhalation of volatile gases is harmful to respiratory tract.
If it is made of batteries, the contents of the batteries are harmful to people's health. It is not recommended to go. You should bring a gas mask or a mask to work. Before I unconsciously opened a battery ingredient bucket, I smoked it, and I couldn't eat a meal a day. If I am making a bag, it will have no effect on my health (individual workstations need to be exposed to organic solvents), which is harmful;
3. Radiation. The so-called radiation refers to the phenomenon that radio frequency waves generated by high-frequency oscillation of the circuit are emitted into space. Radiation with a certain frequency and intensity has an impact on the body;
Extended data:
For the "activation" of lithium batteries, there are many sayings: the charging time must exceed 12 hours, and it must be repeated three times before the battery can be activated. This statement that "the first three charges should last more than 12 hours" is obviously a continuation from the statement of nickel batteries (such as nickel cadmium and nickel hydrogen). So this statement can be said to have been misinformed from the beginning.
The charging and discharging characteristics of lithium batteries and Ni-MH batteries are very different. It can be clearly told that all the serious and formal technical materials I have consulted emphasize that overcharge and overdischarge will cause great harm to lithium batteries, especially liquid lithium-ion batteries. Therefore, it is best to charge according to the standard time and method, especially not more than 12 hours (the charger shows full).
