Is BYD negative workshop feed harmful?

Feeding in BYD negative electrode workshop is harmful. The reason for this is the following：

1, BYD's cathode workshop feeding materials are generally polluted, but the pollution is not big compared with lead-acid batteries, because it does not use heavy metals, which belongs to light pollution industrial projects, but the following aspects should also be paid attention to in production.

2. Powder material is nontoxic, but it needs inhalation protection.

3. Styrene-butadiene rubber has certain toxicity, NMP has slight toxicity, which can prevent inhalation, but it has no obvious effect, so it needs to be highly corrosive to prevent contact with the body.

4. Electrolyte has certain toxicity to prevent excessive inhalation and corrosiveness.
