What is the Principle of Ni-Cd Battery?

As a Ni-Cd Battery Pack Supplier, share with you. The active material on the positive plate of a Ni-Cd Battery is composed of nickel oxide powder and graphite powder. Graphite does not participate in chemical reactions and its main function is to enhance electrical conductivity. The active material on the negative plate is composed of cadmium oxide powder and iron oxide powder. The function of the iron oxide powder is to make the cadmium oxide powder have higher diffusivity, prevent agglomeration, and increase the capacity of the polar plate. The active materials are wrapped in perforated steel strips, and after being pressed and formed, they become the positive and negative plates of the battery. The polar plates are separated by alkali-resistant hard rubber insulating rods or perforated PVC corrugated plates. The electrolyte is usually potassium hydroxide solution. Compared with other batteries, the self-discharge rate of NiCd batteries (that is, the rate of loss of charge when the battery is not in use is moderate). During the use of NiCd batteries, if they are not completely discharged, they will be recharged.

What Is the Basic Characteristic of Ni-Cad Battery?

1.Ni-Cad Battery can be repeated more than 500 times charge and discharge, it is very economical.

2.The internal resistance is small, which can be used for discharging large current. When it discharge, the voltage is small, as a DC power supply, it is a kind of high quality Ni-Cd Rechargeable Battery Pack.

3.Because of the completely sealed type, there will be no electrolyte leakage phenomenon, and no need to add electrolyte.

4.Compared with other types of battery, Ni-Cd battery can withstand overcharge or let electricity, the operation is simple and convenient.

5.Long time placement will not deteriorate the performance, and when the power is fully charged, the original characteristics can be restored.

6.Ni-Cd battery can be used in a wide range of temperature.

Ni-Cd Battery Cell Performance:

1. Ni-Cd Cell Charge Curve At 0.1C For 16h At 55 Degree
