When a nickel-cadmium battery
is overcharged at a low temperature, the positive electrode active material generally swells, and its operational life is shortened.
The clean, consumer-type nickel-cadmium battery cells are placed in a cadmium recovery furnace.
The cadmium reclaimed from this new operation is returned to nickel-cadmium battery manufacturers.

Market Drivers and Technology Factors
ERC's non-metallic nickel electrode contains approximately 40 percent less nickel than that which is found in the typical nickel-cadmium battery
," said Allen Charkey, general manager of ERC's battery division.
Each PowerBook includes a rechargeable nickel-cadmium battery
, AC adapter, video-out cable, System 7.
When comparing rechargeable power, the Discman drive's use of the superior lithium-ion battery gives it a competitive advantage over drives that use a nickel-cadmium battery
This contract award will keep ERC in the forefront of its unique high energy nickel-cadmium battery
Memory effect results from repeatedly charging a Nickel-Cadmium battery
before it is fully discharged.
Like the liquid lithium-ion battery (which was on the R & D 100 list last year), the plastic lithium-ion battery delivers three times more high-energy density than a nickel-cadmium battery
of the same weight, and can be recharged 1,000 times while keeping 90 percent of its original capacity.
