Cylindrical LFP Cells
Advantages of cylindrical LFP cells
Compared with other lithium-ion batteries, cylindrical lfp cells have higher safety, longer cycle life and better thermal stability, and are suitable for use in special industrial environments such as mines or deep seas. Its high temperature resistance and reduced risk of thermal runaway give it significant advantages in scenarios that require high safety and long life.
What is a cylindrical battery?
A cylindrical battery is a round, tube-shaped cell widely used for its durability and ease of manufacturing. Common types include Li-ion, NiMH, and NiCd. People more commonly call it by its size. For example, an 18650 lfp battery is 18mm in diameter and 65mm in length.
What material is the casing of a cylindrical battery usually made of?
Cylindrical battery casings are typically made from usually stainless steel or aluminum. These materials provide durability, protection, and help with heat dissipation, ensuring the battery's safety and longevity.
What is the difference between cylinder and pouch battery?
Cylindrical Battery:
Shape: Round, tube-shaped.
Casing: Metal (usually stainless steel or aluminum).
Durability: Highly durable and resistant to physical damage.
Heat Dissipation: Good thermal management due to metal casing.
Common Uses: Electronics, electric vehicles, power tools.
Pouch Battery:
Shape: Flat, flexible, and rectangular.
Casing: Soft, laminated foil.
Durability: Less durable compared to cylindrical batteries, more prone to physical damage.
Heat Dissipation: Less efficient thermal management.
Common Uses: Smartphones, tablets, drones, electric vehicles.
What are the cylinder batteries called?
Cylindrical batteries are commonly named by their size designations, such as 18650 (18mm x 65mm), 21700 (21mm x 70mm), 26650 (26mm x 65mm), 14500 (14mm x 50mm), and CR123A (17mm x 34.5mm). These batteries are widely used in laptops, flashlights, power tools, cameras, and security devices.
What is the voltage of lfp cylinder battery?
The nominal voltage of lithium iron phosphate batteries is usually 3.2V. The voltage when fully charged is about 3.6V, and the minimum safe voltage when discharged is about 2.5V.
