What chemistry does a nickel cadmium battery use?

Electrochemistry of nickel-cadmium batteries The nickel-cadmium battery uses nickel hydroxide as the active material for the positive plate, and cadmium hydroxide for the negative plate.

How long do nickel cadmium batteries last?

Nickel-cadmium (NiCd) batteries typically last 15–20 years in emergency applications due to their robust thermal stability, deep discharge tolerance, and low self-discharge rate. They excel in critical systems like fire alarms and backup power where reliability is paramount. Regular maintenance, such as periodic full discharges, ensures longevity.

Why is nickel cadmium battery better than lead acid battery?

Thus, through its electrochemistry, the nickel-cadmium battery has a more stable behavior than the lead acid battery, giving it a longer life, superior characteristics and a greater resistance against abusive conditions. Nickel-cadmium cells have a nominal voltage of 1.2 volts. Material: hard PVC plastic. Material: polypropylene.

What is a nickel cadmium cell?

fulfill all requirements specified 60623. The nickel-cadmium cell consists of two groups of plates, the positive containing nickel hydroxide and the negative containing cadmium hydroxide. The active materials of the Saft Nife pocket plate block battery are retained in pockets formed from steel strips double-perforated by a patented process.

How to choose a nickel-cadmium battery?

In discharging the nickel-cadmium battery, the cell voltage should be taken as low as possible in order to find the most economic and efficient battery. This is the electrical performance required from the battery for the application.

Can Ni-Cd batteries be recycled?

Ni-Cd batteries must not be discarded as harmless waste and should be treated carefully in accordance with local and national regulations. Your Saft representative can assist with further information on these regulations and with the overall recycling procedure.
