Analysis of Cylindrical Lithium Battery Advantages and Common Models
1. Definition of cylindrical lithium battery Cylindrical lithium battery is a kind of lithium ion battery, its shape is cylindrical, so it is called cylindrical lithium battery. The structure of a typical cylindrical battery includes: casing, cap, cathode, anode, separator, electrolyte, PTC element, gasket, safety valve, etc. Generally, the battery shell is the anode of the battery, the cap is the cathode of the battery, and the battery shell is made of nickel-plated steel plate. They are able to supply stable power with a flat discharge voltage and a high reliability. Last but not least, their low self-discharge is impressive. The usage of our Li-Ion batteries requires a safety unit. 2. The Development History of Cylindrical Lithium Batteries Since Tesla’s Battery Day in September 2020 introduced the 4680 large cylindrical cells, these cells have once again become a focal point in the battery industry. In addition to Tesla, leading battery manufacturers in China have also ...
