rechargeable batteries > Nickel Cadmium (NiCd)

NiCad makes an efficient and very cost-effective source of rechargeable power for a wide range of portable electrical and electronics equipment: cordless power tools and appliances, test instruments, radio transceivers, model boats, cars and aircraft, etc.

Nickel-cadmium rechargeable cells are constructed of alternating layers of porous, negative cadmium anode and porous, positive nickel oxide cathode separated by absorbent layers, all permeated by electrolyte and surrounded by a nickel-plated steel case.”

 

 

Advantages

Disadvantages

Low Cost.	Poor Shelf Life.
Rapid Recharge Capability.	Environmental Impact of Cadmium.
	"Memory-Effect"- develops when cells are constantly partially discharged to the same %.
	Lowest Energy Density - Requires larger size cells for same energy output.
