nickel cadmium
Old rechargeable cell
Nickel cadmium describes a type of rechargeable battery using nickel oxide hydroxide and metallic cadmium as electrodes.
These batteries were standard in portable electronics before lithium-ion technology displaced them: My old cordless drill still runs on nickel cadmium.
Often abbreviated NiCad or NiCd.
The cadmium content makes disposal an environmental concern.
