Product performance:

1. High life. The Ni Cd battery can provide more than 500 charge and discharge cycles, and its service life is almost equal to the service life of the equipment using the battery.More charge/discharge cycles than other rechargeable batteries to extend battery life.

2. Excellent discharge performance. In the case of high current discharge, nickel cadmium battery has low internal resistance and high voltage discharge characteristics, so it is widely used ang withstand long periods of deep discharge.

3. Reliable safety valve. The safety valve provides maintenance free function. Nickel cadmium battery can be used freely in the process of charge discharge or storage. Due to the special material used in the sealing ring and the effect of sealant, the leakage phenomenon of Ni Cd battery is rare.

4. High rate charging performance. The nickel cadmium battery can be quickly charged according to the application needs, and the full charge time is only 1.2 hours.

5. Wide range temperature adaptability.Ordinary nickel cadmium batteries can be used in high or low temperature environment. High temperature batteries can be used at temperatures of 70 degrees Celsius or higher.

6. A wide range of applications. The capacity of nickel cadmium battery ranges from 100mah to 7000mah. There are four types commonly used: standard type, consumer type, high temperature type and high current discharge type, which can be applied to any wireless device.

7.Higher energy density, lighter and more compact than lead-acid batteries Ni-Cd is preferred when size and weight are critical factors, such as in aircraft.

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

How Ni-Cd Batteries are Special?

'NiCd' is the chemical abbreviation for the composition of Ni-Cd Battery, which are a type of secondary (rechargeable) batteries. Nickel-Cadmium batteries consist of the chemicals Nickel (Ni) and also Cadmium (Cd), in numerous types and also make-ups. Normally the positive electrode is made of Nickel hydroxide (Ni (OH) 2) as well as the negative electrode is made up of Cadmium hydroxide (Cd (OH) 2), with the electrolyte itself being Potassium hydroxide (KOH).

NiCd batteries are different from normal alkaline batteries or lead-acid batteries in a number of key methods. One of the primary vital distinctions is in cell voltage. A common alkaline or lead-acid battery has a cell voltage of about 2V, which after that gradually hands over as it is depleted. NiCad batteries are unique because they will maintain a consistent voltage of 1.2 v per cell up till it is nearly totally diminished. This causes the NiCad batteries to have the ability to provide full power outcome up till completion of its discharge cycle. So, while they have a reduced voltage per cell, they have a more powerful delivery throughout the entirety of the application. Some suppliers comprise the voltage difference by adding an added cell to the battery pack. This allows for the voltage to be the like the standard kind batteries, while still keeping the continuous voltage that is so unique of NiCads. Another factor the NiCad batteries can provide such high power output, is they have very low interior resistance. Since their internal resistance is so reduced, they can releasing a lot of power extremely swiftly, along with accepting a great deal of power really swiftly. Having such a low inner resistance maintains the internal temperature level reduced as well, permitting fast fee as well as discharge times. This attribute, incorporated with the constant voltage of the cells, permits them to produce a high quantity of amperage, at a constantly greater voltage than equivalent alkaline batteries.
