The nickel–cadmium battery (Ni–Cd battery or NiCad battery) is a type of rechargeable battery using nickel oxide hydroxide and metallic cadmium as electrodes. At that time, the only direct competitor was the , which was less physically and chemically robust. Larger flooded cells are used for ,and marginally in ,Vented-cell (wet cell, flooded cell) Ni–Cd batteries are used when large capacities and high discharge rates are required. A fully charged Ni–Cd cell contains:• apositive • anegative electrode plate• a
Most of the uses described below are shown for historical purposes, as sealed (portable) Ni-Cd batteries have progressively been displaced by higher performance Li-ion cells, and their placing on the EU market has, for the most part, been prohibited since 2006 by the 2006/66/EC EU. Ni–Cd cells are available in the same sizes as , from AAA through D, as well as several multi-cell sizes, including the equivalent of a 9-volt.
