Product FAQ's

What are the cylindrical cell formats?

Cylindrical cells come in standard formats like 18650 (18×65 mm), 21700 (21×70 mm), 26650 (26×65 mm), and 32650 (32×65 mm). The numbers indicate diameter and length in millimeters. 21700 cylindrical cells are widely used in EVs and energy storage for higher energy density.

What are the characteristics of cylindrical cells?

Cylindrical cells offer high mechanical stability, easy heat dissipation, standardized sizes, and good energy density. They are commonly used in power tools, electric vehicles, and battery packs due to their reliability and long cycle life.

What is the specification of a cylindrical cell?

A typical 21700 cylindrical cell has:

Nominal Voltage: 3.6V–3.7V

Capacity: 4000–5000 mAh

Cycle Life: 500–2000+ cycles

Max Charge/Discharge Current: Varies by model (up to 10A or more)
Specifications can vary based on the chemistry (e.g., NMC, LFP, LCO) and manufacturer.

What are the main components of a cylindrical battery cell?

A cylindrical cell includes the anode (usually graphite), cathode (like NMC or LFP), separator, electrolyte, metal casing, current collectors, and safety components like a PTC and CID.

What is the standard size and format of 21700 cylindrical cells?

A 21700 cylindrical cell measures 21 mm in diameter and 70 mm in length. It is widely used in EVs and energy storage due to its higher capacity compared to 18650 cells.

How is cylindrical cell preparation different from coin cell preparation?

In cylindrical cell preparation, electrodes are wound into a jelly-roll structure, inserted into a metal casing, filled with electrolyte, sealed, and aged. Coin cell preparation uses stacked layers and crimping in stainless steel cases.

What safety features are included in cylindrical cell components?

Cylindrical cells contain built-in safety elements like PTC (positive temperature coefficient), CID (current interrupt device), and vent caps to prevent overpressure, overheating, or short circuits.
