I work in battery manufacturing and it's not. The type of cells used in vapes are Lithiun iron phosphate. Once you open the cells up, they're essentially rust.

I work in battery manufacturing and it's not. The type of cells used in vapes are Lithiun iron phosphate. Once you open the cells up, they're essentially rust. There is some material that can be pulled from them but companies pay to remove them because the cost of extraction is more Than the cost of using fresh materials. This is the dirty secret regarding lithium cells. At the very least, using C grade cells in this manner ensures a working product gets used for some application even if it is disposable. Take solice in the fact that when you throw batteries out in landfill trash that most are picked up by high powered magnets and are separated out for recycling.
