What is NiCd Battery?
A Nickel-cadmium (Ni-Cd) battery is a type of rechargeable battery that uses nickel oxide hydroxide and metallic cadmium as electrodes. It is a popular type of battery due to its reliability, long cycle life, and high energy density.
Ni-Cd batteries are often used in portable electronic devices, such as cordless phones, power tools, and digital cameras. They are also used in emergency lighting, backup power systems, and other applications that require reliable and long-lasting power.
Advantages of Ni-Cd battery:
1.Reliability: Ni-Cd batteries are known for their long cycle life and consistent performance over many charge-discharge cycles. They can typically withstand hundreds to thousands of cycles without significant degradation, making them reliable for various applications.
2.High Discharge Rates: Ni-Cd batteries can deliver high discharge currents, which makes them suitable for applications that require bursts of power or high-energy output, such as power tools and some portable electronic devices.
-
3.Temperature Tolerance: Ni-Cd batteries can operate effectively in a wide range of temperatures, from sub-zero conditions to relatively high temperatures, without significant loss of performance. This attribute makes them suitable for use in extreme environments.
-
-
4.Fast Charging: Ni-Cd batteries have relatively fast charging times compared to some other rechargeable battery chemistries. They can accept a high rate of charge without sustaining damage, making them convenient for applications where quick recharge times are essential.
-
-
5.Stable Voltage Output: Ni-Cd batteries provide a stable voltage output throughout the discharge cycle, which is advantageous for devices that require consistent power delivery.
-
-
6.Low Self-Discharge Rate: While Ni-Cd batteries do experience some self-discharge over time, it is relatively low compared to other rechargeable battery types. This characteristic makes Ni-Cd batteries suitable for applications where long-term storage is required.
-
-
7.Economical: Although newer battery technologies have emerged, Ni-Cd batteries remain cost-effective for certain applications. They typically have a lower upfront cost compared to some other rechargeable battery chemistries.
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
Brief Introduction of Ni-Cd Battery
Ni-Cd Battery is a DC power supply battery, it can be repeated more than 500 times charge and discharge, economical and durable. Its internal resistance is small, can quickly charge, but also for the load to provide large current, and discharge voltage change is very small. It is the earliest type of battery used in mobile phones, super instruments, Emergency Lighting Products, it has good high current discharge characteristics, strong ability of overcharge and discharge, simple maintenance and so on.
The most fatal disadvantage of Ni-Cad Battery is that if memory is not handled properly during charging and discharging, serious “memory effect” will occur, which will shorten service life greatly. Of course, we can reduce the “memory effect” by mastering the reasonable charging and discharging method.
