Lithium Battery Cell vs ICR21700 Comparison

Lithium Battery Cell Advantages

Lightweight and flexible aluminum-plastic packaging under 1mm thickness
20-40% lighter than equivalent capacity steel/aluminum-cased batteries
High safety with bulging/leakage rather than explosion during abuse
Excellent low-temperature performance with over 70% capacity in sub-zero environments
Low internal resistance

Lithium Battery Cell Disadvantages

Lower mechanical strength, susceptible to puncture or compression damage
Higher cost due to customized production

21700 Lithium-ion Battery Advantages

High energy density
Cost-effective standardized production
Rugged metal casing for mechanical protection
High rate discharge capability
Long cycle life exceeding 500 cycles

21700 Lithium-ion Battery Disadvantages

Fixed cylindrical shape with low space utilization
Higher safety risks with potential thermal runaway
Larger size and weight (Φ21.4mm * 70.6mm, ~69-70g)

Typical Applications

Li-Po Applications

Portable electronics, smartphones, tablets, wearables, drones, RC toys, and thin devices requiring flexible power solutions

Cylindrical Li-ion Applications
