Discover how to select the right cylindrical lithium battery models for your industrial applications. Explore technical specifications, industry applications, and market trends in this detailed guide.
Why Model Classification Matters in Energy Storage?
With global lithium battery demand projected to reach 4.7 TWh by 2030 (BloombergNEF 2023), understanding cylindrical battery models has become critical for engineers and procurement specialists. These standardized power cells form the backbone of modern energy solutions across industries.
Standard Models and Dimensions
- 18650: 18mm diameter × 65mm length – the "AA battery" of lithium cells
- 21700: 21mm × 70mm – balances capacity and compactness
- 26650: 26mm × 65mm – preferred for high-drain applications
- 32650: 32mm × 67.7mm – industrial-grade power solutions
Model | Capacity (mAh) | Continuous Discharge (A) | Typical Applications |
---|---|---|---|
18650 | 2000-3500 | 10-20 | Portable devices, e-bikes |
21700 | 4000-5000 | 30-45 | EVs, power tools |
26650 | 5000-6000 | 20-35 | Solar storage, UPS |
Industry-Specific Selection Guide
Choosing the right model resembles selecting shoes - you need the perfect fit for your application:
