Specific Processes for the Treatment of Nickel Cadmium Batteries

2/ SPECIFIC PROCESSES FOR THE TREATMENT OF NICKEL CADMIUM BATTERIES 

The methods specific to the treatment of nickel cadmium, and thus of NiMH, fall into three categories  

In Europe, two companies at least have tried to develop mechanical processes. 

In the magnetic part, the cadmium content was consistently above 1% except for pieces of 10 to 2 mm in which the cadmium content fell to 0.6%. 

In the non-magnetic powders, pieees of 20 to 5 mm had a content below 1% but only represented 4.5% by weight of the batteries.
