Cylindrical lithium-ion battery cells are a type of rechargeable battery commonly used in a wide range of electronic devices, electric vehicles, and energy storage systems. They are characterized by their cylindrical shape, standardized sizes, and high energy density, making them versatile and suitable for various applications.
Cylindrical lithium battery capacity The rated energy density of a single cylindrical lithium battery is between 300 and 500Wh/kg. Its specific power can reach more than 100W. According to different models and specifications of cylindrical batteries, the actual performance of this type of battery varies.
Common cylindrical battery cell capacities are as follows: 3. Cylindrical battery pack voltage Common cylindrical battery pack voltages are 3.2V, 3.7V, 6.4V, 7.4V, 9.6V, 11.1V, 12V, 14.8V, 22.2V, 24V, 36V, 48V, etc.
Cylindrical lithium batteries are more suitable for large-volume automated combination production. Large-volume lithium-ion batteries such as electric bicycles and electric motorcycles are basically produced from cylindrical lithium batteries.
