What is a round lithium battery?
The round lithium battery refers to the cylindrical lithium battery. Because the history of the 18650 cylindrical lithium battery is quite long, the market penetration rate is very high. The cylindrical lithium battery adopts various mature replacement processes, the degree of automation is high, and the product mass transfer is stable.
What is a cylindrical battery?
Cylindrical cells are small and round, making it possible to stack them in devices of all sizes. Unlike other battery formats, their shape prevents swelling, an undesired phenomenon in batteries where gasses accumulate in the casing. Cylindrical cells were first used in laptops, which contained between three and nine cells.
Why should you choose a cylindrical battery?
Cylindrical cells benefit from economies of scale and widespread use, contributing to cost-effectiveness. In the ever-evolving landscape of lithium-ion battery technology, the choice between prismatic, pouch, and cylindrical cells depends on the specific requirements of the application.
What are the different types of battery cells?
Battery cells appear in different outer shapes. The shapes can be divided into a cylindrical and prismatic geometry, whereas the prismatic shape can be further divided according to the housing stability into the prismatic hard-case cell and the prismatic pouch cell .
What is a rectangular battery with high energy density?
The aluminum-shell rectangular battery with high battery energy density is mainly because the structure of the rectangular battery is simple, unlike the cylindrical battery, which uses high-strength stainless steel as the housing and accessories such as explosion-proof safety valves, the overall accessory weight is light.
What is a battery cell?
A battery cell consists of at least one, usually more bundled secondary cells which are electrically connected with a tab to increase either the overall voltage or capacity.
