except they use a metal alloy negative electrode which adsorbs hydrogen. The hydride electrode has a higherenergy densitythan Cd, thus a higher capacity for the same size. NiMH batteries are more environmentally safe than Ni-Cd since there is no cadmium, making disposal easier. Like Ni-Cd, ...
Although nickel metal hydride cells do not have the same memory effect seen in NiCd cells, that is, the formation of intermetallic crystals of nickel and cadmium, they do have considerable passivation if the cells are not maintained well. Storing nickel metal hydride batteries on the shelf at ...

Nickel(II) hydroxide also finds use in batteries, specifically in nickel-metal hydride (NiMH) batteries, where it serves as the positive electrode material. Additionally, it has been studied for its potential in wastewater treatment and as a precursor for the synthesis of other nickel compounds. ...
Finely divided nickel absorbs a large volume of hydrogen at high temperatures. Even at ordinary temperatures, considerable occlusion of hydrogen occurs on to the metal surface and no definite composition of any hydride formed is known. The metal activates molecular hydrogen to its atomic state, contr...

There is nothing new about recycling batteries and waste products from nickel鈥揷admium batteries. Several developments have occurred in the past few years. National and international regulations are prohibiting to an ever-increasing extent the disposal of nickel-cadmium batteries on rubbish tips as ...
