With present technology the risk in manufacturing Cadmium is certainly less than what is used to produce a Lithium-Ion battery. The major danger from Cadmium during processing is inhalation and that is not terribly difficult to counteract as it's a concern with many different materials. Most iron ore processing spews cadmium dust all over the place, frankly.

In any case, you'll find that Cadmium use is still very extensive in specialized, commerical batteries and is very heavily used in electroplating and in the production of PVC.


I suspect the real reason that Cadmium may have disappeared is that you can't easily store large amounts of it and the price volatility tends to be ridiculous. It can swing 300% in a quarter in either direction.
