Electronic cigarette battery cathode materials include three kinds: pure cobalt series, ternary series, and the two mixed series. 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 ternary discharge platform is mainly 3.6-3.7V. There are also high requirements for discharge rates, with 8-10C discharge rates, such as 13350 and 13400 models, to achieve 3A continuous discharge capacity. The disadvantage of pure cobalt batteries is that they are slightly more expensive.
The models with more market shipments include 08570 300mah, 13350 500mah, 13400 550mah, 17350 850mah, 18350 950mah, 651545 350mah and so on.
