Despite lithium-ion batteries being more widely used and environmentally friendly, nickel-cadmium (NiCd) batteries still have applications where they are preferred due to their unique characteristics:
Why NiCd Batteries Are Still Preferred
1. Robustness and Durability
- Handling Extreme Conditions: NiCd batteries can withstand rough handling, shocks, and vibrations, making them suitable for environments where durability is crucial.
- Wide Temperature Range: They operate well from -20°C to 60°C, which is beneficial for applications requiring flexibility in different climates.
2. Cost and Availability
- Affordability: NiCd batteries are generally cheaper than lithium-ion batteries, making them a cost-effective choice for certain applications.
- Supply Chain: In some regions or industries, NiCd batteries might be more readily available.
3. Specific Industrial Needs
- Power Tools and Equipment: NiCd batteries are still used in power tools like drills and saws due to their ability to deliver high discharge rates, which is important for these energy-intensive applications.
- Aviation and Industrial Equipment: They are used in some industrial and aviation applications where their durability and consistent performance are beneficial.
4. Emergency Backup Power
- Reliability in Emergencies: NiCd batteries are sometimes chosen for emergency backup systems due to their robustness and ability to perform well under harsh conditions.
Overall, while lithium-ion batteries have surpassed NiCd in many areas, the latter still holds its ground in scenarios requiring specific durability and cost benefits. However, environmental concerns and the presence of toxic cadmium in NiCd batteries mean that their use is diminishing in favor of more sustainable options.
