Are nickel cadmium batteries better than lead-acid batteries?
Lining up lead-acid and nickel-cadmium we discover the following according to Technopedia: Nickel-cadmium batteries have great energy density, are more compact, and recycle longer. Both nickel-cadmium and deep-cycle lead-acid batteries can tolerate deep discharges. But lead-acid self-discharges at a rate of 6% per month, compared to NiCad’s 20%.
What happens if you overcharge a lead acid battery?
Over-charging a lead acid battery can produce hydrogen-sulfide. The gas is colorless, very poisonous, flammable and has the odor of rotten eggs. Hydrogen sulfate also occurs naturally gases, natural gas, and some well waters. Being heavier than air, the gas accumulates at the bottom of poorly ventilated spaces.
How do lead-acid batteries work?
Lead-acid batteries use lead derivatives for their electrodes, and a diluted solution of sulfuric acid for their electrolytes. Their chemistry takes place inside stout cases, and there are few incidents provided they are correctly handled.
Can cadmium be replaced with metal hydrides?
Some progress has been made already by battery companies in their development of environmentally safe batteries, notably by the reduction of the mercury content of batteries and the development of a technology that may make it possible to replace the cadmium in Ni/Cd batteries with metal hydrides.
How can cadmium be removed from a battery?
Foremost is the reduction of mercury in alkaline cells to <.025%, with a continuin effort to completely eliminate mercury from this system. In the area of Ni/C batteries, much work is underway to develop a Ni/metal hydride system, to eliminate cadmium.
Why do battery manufacturers recycle lead?
Although battery manufacturers began to recycle lead for economic reasons long before its harmful effects were fully recognized, the general awareness of its toxicity had led them to limit worker exposures and to limit the amount of lead discharged from their lants. The case of mercury is similar in some respects.
