How To Choose A Disposable E-Cigarette Battery

January 16, 2024

Electronic cigarettes as consumer electronics products, battery life, safety is an important factor affecting the quality of electronic cigarette product experience.

First, electronic cigarette battery types
According to the shape and hard and soft to see, electronic cigarette batteries are divided into soft pack and hard shell, cylindrical and square, the combination of cylindrical soft pack batteries, square soft pack batteries, cylindrical steel shell batteries and other types.
Early big cigarettes used more cylindrical hard shell batteries, there are well-known models such as 18650, while today's e-cigarettes are mainly used in soft pack batteries, specifically square or cylindrical depends on the product design, which has a good safety, high capacity, ultra-thin and lightweight, high stability, high rate of discharge, design with flexibility and other aspects of the advantages.
According to different anode materials, there are three kinds of e-cigarette batteries: pure cobalt series, ternary series, and mixed series.
Pure cobalt is the main material in the market, which has the advantages of high discharge voltage platform, large discharge rate and high energy density, etc. The voltage platform of pure cobalt is between 3.4-3.9 V, and the discharge platform of ternary is mainly 3.6-3.7 V. There are also high requirements for the discharge rate, and it has a discharge rate of 8-10 C. For example, the 13350 and 13400 models have to achieve the capacity of continuous discharge of 3A.

Second, the characteristics of the electronic cigarette battery
Currently in the electronic cigarette market, the battery is divided into two categories, disposable e-cigarette batteries and repeatable e-cigarette batteries.
Disposable e-cigarette battery characteristics:
● Fast consumables, high demand
● The cost is basically the same as that of secondary recyclable batteries.
● Difficulty in recycling, not easy to handle
● High resource consumption, which is not conducive to sustainable human development.
Repeatable e-cigarette battery characteristics:
● Battery technology is higher than disposable
● Batteries are shipped in a semi-electrified state and stored in a stable state.
● Relatively low resource consumption
● Can make full use of fast charging technology and high cycle technology

Third, the choice of electronic cigarette battery

The selection of e-cigarette batteries can be considered in terms of shape, size, electrical performance, environmental performance, safety performance and other aspects.

Battery Selection Items	Selection principles	Cautions
Shape	Decide whether to use cylindrical or square batteries according to the design of the electronic cigarette structure	When choosing to use cylindrical batteries, be sure to pay attention to the space occupied by the microphone cable.
Dimension	According to the design of the battery compartment to determine the size of the battery	The dimensions in the direction of the battery thickness must allow for the expansion space of the battery
Electrical Performance	Generally, disposable e-cigarette batteries can meet more than 300 puffs, and secondary performance batteries should also meet the cycle of 300 weeks.	Too high energy ratio requirement will reduce the consistency and safety of the battery.
Environmental Performance	-20℃-60℃ use environment	Considering the use environment and charging environment of the battery, low temperature is not conducive to charging.
Safety	Meet the standard of GBT31241	Generally, the battery is easy to be crushed and impacted by heavy objects.
	Meet the standard of IEC62133
	Meet the standard of UL1642
