Panama Container NiCd Battery Life

What is a nickel cadmium battery?

Nickel cadmium (NiCd) batteries are electrochemical devices that consist of a cadmium hydroxide negative anode and a nickel hydroxide positive cathode, capable of operating well at low temperatures, with a higher energy density and lifespan compared to lead acid batteries, but hindered by a memory effect and environmental concerns due to cadmium.

Why are Ni-Cd batteries so expensive?

One of the most remarkable problems associated with a Ni–Cd battery is based on their high cost due to expensive cadmium and nickel materials used in the construction. Environmental constraint is most likely encountered using the battery on the circumstance that the heavy metallic materials used are not well disposed-off.

What are the advantages and disadvantages of Ni-Cd battery?

Ni-Cd battery advantages consist of long cycle life, durability, good charge retention, excellent long-term storage, low maintenance, and flat discharge. The major disadvantages are low energy density, high cost relative to Pb-A batteries, and strong memory effects .

Can Ni-Cd be used for energy storage?

An application of Ni–Cd can be found in the battery energy storage system of Golden Valley Association project in Alaska where it provides 27 MW for 15 min. The battery string can be reconfigured to produce a full 40 MW also in 15 min .
