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
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
