NiMH Battery Recycling?

NiMH Battery Recycling?Even though
the emphasis in battery research has shifted away from NiCd to newer technologies, the
NiCd battery continues to be one of the most used
rechargeable batteries. Over 75 million NiCd batteries were sold in the US during the year
2000. Market reports indicate that the demand of NiCd

until 2003. The demand for other chemistries, such as the NiMH and Li-ion family,You are not allowed to view links. Register or Login, is
rising at a more rapid pace. Where will the mountains of

The lead acid battery has led the way in
recycling. The automotive industry should be given credit in organizing ways to dispose of
spent car batteries. In the USA, 98 percent of all lead acid

(65 percent), newspaper (59 percent) and glass bottles (37 percent), lead acid

part to legislation.
Only one in six households in North America recycle rechargeable

batteries to a recycling center is a challenging task. Homeowners have the lowest return
ratios, but this should improve once more recycling repositories become available and
better environmental awareness is emphasized.
Careless disposal of the NiCd is very hazardous to the environment. If used in
landfills, the cadmium will eventually dissolve itself and the toxic substance will seep
into the water supply, causing serious health problems. Our oceans are already beginning
to show traces of cadmium (along with aspirin, penicillin and antidepressants) but the
source of the contamination is unknown.
Although NiMH batteries are considered environmentally friendly,You are not allowed to view links. Register or Login, this chemistry is
also being recycled. The main derivative is nickel, which is considered semi-toxic. NiMH
also contains an electrolyte that, in large amounts, is hazardous to the environment.

wastes. If ten or more batteries are accumulated, the user should consider disposing the
batteries in a secure waste landfill.
