nickel cadmium uses

What are nickel cadmium batteries used for?

A nickel-cadmium battery (NiCd or NiCad) is a rechargeable battery used for portable computers, drills, camcorders and other small battery-operated devices requiring an even power discharge.NiCds use electrodes made of nickel oxide hydroxide, metallic cadmium and an alkaline electrolyte of potassium hydroxide.

Ni-Cd or NICKEL-CADMIUM CELLS

1. Active materials are nickel hydrate (NiOOH) in the charged positive (+ve)plate (Anode) and . 2. sponge cadmium (Cd) in the charged negative(-ve) plate (Cathode).. 3. The electrolyte is a potassium hydroxide (KOH) solution in concentration of 20-34 percent by weight pure KOH in distilled water.. What happens during the end of the charging cycle? 1. the cells emit gas.

5 Important Uses of Nickel | Refractory Metals and Alloys

5 Important Uses of Nickel. Nickel is a silver-white metal with element symbol Ni and a relative atomic mass of 58.69. Nickel has a density of 8.9g / cm³, a melting point of 1455 ° C, and a boiling point of 2730 ° C. Because nickel is hard, has good ductility, magnetic and corrosion resistance, and can be highly polished, it has been widely used in industry and our daily lives.

Nickel–cadmium battery - Wikipedia

Cadmium (Cd) is a soft, malleable, bluish white metal found in zinc ores, and to a much lesser extent, in the cadmium mineral greenockite. Most of the cadmium produced today is obtained from zinc byproducts and recovered from spent nickel-cadmium batteries. First discovered in Germany in 1817, cadmium found early use as a pigment because of its ...

Nickel Cadmium Battery - an overview | ScienceDirect Topics

Nickel–cadmium batteries. Nickel–cadmium batteries at the 1–2h rate yield twice the energy density of lead-acid batteries, i.e. about 50 W-h/kg. They operate over a wide temperature range, give approximately 2000 cycles, and can be charged in less than 1 h. Nickel–cadmium batteries are used in various developmental electric vehicles.
