As the name shows, e-cigarette must be powered by electricity. Therefore, battery is one of the necessary components of vapes. Battery life and safety are important factors affecting the quality experience of e-cigarette products. You can check Vaporesso XROS 3 VS XROS 2 POD here.
E-cigarette batteries can be divided into soft pack and hard shell, cylindrical and square, combined with cylindrical soft pack battery, square soft pack battery, cylindrical steel shell battery and other types.
Early tobacco use is more cylindrical hard shell battery, well-known models such as 18650. And now the main application of electronic cigarettes is soft pack battery, the specific square or cylinder depends on the product design, it has good safety, high capacity, ultra-thin and lightweight volume, strong stability, high rate discharge, elastic design and other advantages.
There are three types of cathode materials for e-cigarette batteries: pure cobalt, ternary, and a combination of the two.
The mainstream material in the market is pure cobalt, which has the advantages of high discharge voltage platform, large rate discharge, high energy density, etc. The voltage platform of pure cobalt is between 3.4-3.9V, and the three-way discharge platform is mainly 3.6-3.7V. There are also higher requirements for discharge rate, with 8-10C discharge rate, such as 13350 and 13400 models, to achieve 3A continuous discharge capacity.
The development of disposable e-cigarettes is driving the demand for batteries, and is also pushing e-cigarette batteries toward higher energy density (higher battery life), smaller size, and higher safety. So the battery maker is more and more important in the electronic cigarette industry chain.
