A startling experiment indicates that you may need to ensure that you use the correct charger for your e-cigarette.
London charity "Electric Safety First" has released a video showing a strong explosion caused by a small lithium-ion battery inside an electronic cigarette.
The electronic cigarette is an electronic device, similar to smartphones and electric cars. It contains a lithium-ion battery which, if punctured, damaged, or overheated, can lead to a fire or explosion. Like your phone, the e-cigarette battery also needs to be charged, but only with the included charger.
What are lithium-ion batteries?
Lithium-ion batteries are rechargeable batteries that use lithium ions to move between the negative (anode) and positive (cathode) electrodes during charging and discharging. These batteries contain lithium that exists only in ion form within the electrolyte. Due to their ability to store large amounts of power, lithium-ion batteries are widely used in consumer electronics such as smartphones and personal computers, as well as industrial robots, production equipment, and automobiles.
The video depicts a small silver e-cigarette being overcharged with an incorrect USB connector, causing the battery inside the device to reach a voltage beyond its capacity. This resulted in a state of "thermal runaway" and a violent explosion within a protective organic glass container.
The thin line in the video is a thermocouple, used to measure the temperature of the e-cigarette, monitored by a yellow thermometer. According to the charity organization, the e-cigarette device in the video is unbranded and was purchased from the local market or online.
Meanwhile, the charger in the video is a USB connector, but it's not the one provided with the electronic cigarette at the time of purchase.
The UK government has emphasized the importance of using the correct electronic cigarette charger. They stated that "charging should only be done using the charger provided with the electronic cigarette. Do not leave it charging overnight and regularly check your device while charging. Once it is fully charged, unplug your electronic cigarette.
