Product type
Cylindrical lithium cells are a type of rechargeable battery commonly used in electric vehicles (EVs) due to their high energy density and efficiency. These cells are typically constructed with a cylindrical metal casing that houses the anode, cathode, and electrolyte, allowing for effective ion movement during charging and discharging cycles. Their design enables a compact form factor while maximizing energy storage capacity.
| Cell diameter | 18mm to 26mm |
| Cell height | 65mm to 70mm |
| Nominal voltage | 3.6V to 3.7V |
| Capacity | 1500mAh to 5000mAh |
| Chemistry | Lithium nickel cobalt manganese oxide (NCM) or lithium iron phosphate (LFP) |
| Cycle life | 500 to 2000 cycles |
When selecting cylindrical lithium cells, buyers should consider the specific energy requirements of their application, including capacity and voltage ratings. It is also important to specify the desired cycle life and any necessary certifications, such as UN38.3 for transport safety. Additionally, buyers should evaluate the quantity needed based on their production scale and future demand.
