Nickel-Cadmium (Ni-Cd) batteries are one of the oldest and most reliable types of rechargeable batteries. They have been widely used in various industries due to their durability, high discharge rates, and ability to perform in extreme temperatures.
Key Features of Ni-Cd Batteries:
- Rechargeable: Can be recharged hundreds to thousands of times.
- High Discharge Rate: Suitable for high-power applications.
- Wide Temperature Range: Operates efficiently in both cold and hot environments (-20°C to 60°C).
- Long Shelf Life: Holds charge well when not in use.
Common Applications:
- Emergency lighting systems
- Power tools
- Medical equipment
- Aviation and military devices
- Portable electronics (older models)
Despite being overshadowed by newer technologies like lithium-ion, Ni-Cd batteries remain relevant in scenarios where reliability and robustness are critical.
