What is Nickel-Cadmium Battery?
The nickel-cadmium battery (Ni-Cd battery or NiCad battery) is a
rechargeable battery that uses nickel oxide and the metal cadmium
as electrodes.
It is a device that produces a direct current voltage based on a
chemical reaction between related substances. In nickel-cadmium
cells, the REDOX material is used as the base and a nickel layer
and separator are used around it. Nickel-cadmium batteries have a
voltage of about 1.2 V. When in series, usually 3 or 4 cells are
packed together for a 3.6 to 4.8V output.
What is the Principle of Nickel-Cadmium Battery?
As a nickel cadmium battery pack supplier, share with you. The
active material on the positive plate of nickel-cadmium battery
consists of nickel oxide powder and graphite powder. Graphite does
not take part in chemical reactions. Its main role is to enhance
electrical conductivity. The active substance on the negative plate
is composed of cadmium oxide powder and iron oxide powder. The role
of iron oxide powder is to make cadmium oxide powder has a higher
diffusion coefficient, prevent caking, increase the plate capacity.
The active material is wrapped in the perforated steel strip, which
is pressed and formed into the positive and negative plates of the
battery. Plates are separated by alkali resistant hard rubber
insulation rods or perforated PVC corrugated plates. The
electrolyte is usually a potassium hydroxide solution. Compared
with other batteries, nickel-cadmium batteries have a moderate
self-discharge rate, or the rate of charge loss when the battery is
not in use. Nickel-cadmium batteries are charged if they are not
fully discharged during use.
Nickel-cadmium battery features:
The maximum discharge rate of nickel-cadmium batteries varies by
size. For ordinary aa sized batteries, the maximum discharge rate
is about 1.8 amps; The D-size battery can discharge up to 3.5 amps.
Ni-Cd Battery Cell Performance:
1. Ni-Cd Cell Charge Curve At 0.1C For 16h At 55 Degree
2. Ni-Cd Cell Discharge Curve At 0.25C At 55 Degree
3. Ni-Cd Cell Charge Efficiency At Different Temperature
4. Ni-Cd Cell Capacity Change At Permanent Charge At 55 Degree
(0.05C Floating)
5. Ni-Cd Cell Cycle Life Curve
