To deal with battery self-discharge during the storage of electronic cigarettes, measures can be taken from aspects such as storage conditions, charging management, battery quality, usage habits, and regular maintenance. The following are specific countermeasures:
Storage condition optimization
Control temperature: Temperature is one of the important factors affecting battery self-discharge. High temperatures can accelerate the self-discharge rate of batteries. Therefore, electronic cigarettes should be stored in a dry and cool place as much as possible to avoid being exposed to high temperatures for a long time. Generally speaking, 0℃ to 25℃ is a relatively suitable storage temperature range.
Maintain appropriate humidity: An overly humid environment may cause rust and corrosion of the external metal components of the battery, affecting the battery's conductivity and internal circuit connections, and thereby intensifying self-discharge. Therefore, the environmental humidity for storing batteries should be maintained at a moderate level.
Charging management
Avoid overcharging: Overcharging can cause the battery to heat up, increase the side reactions inside the battery, and thereby accelerate self-discharge. The original or compatible charger should be used and the charging should be carried out in accordance with the correct charging method. When the battery is fully charged, the charger should be unplugged in time to avoid overcharging the battery for a long time.
Avoid complete discharge: Lithium-ion batteries should be prevented from being over-discharged until their power is completely depleted. Try to charge the battery when the remaining power is around 20% to 30% to maintain its activity and reduce self-discharge.
Regular charging and discharging: For electronic cigarette batteries that have not been used for a long time, it is recommended to perform a charging and discharging cycle every few months. This can stir and reactivate the chemical substances inside the battery, thereby reducing the rate of self-discharge. When charging, charge the battery to about 40% to 60% before storing it, which can better maintain the battery's performance.
Battery Quality and selection
Select high-quality batteries: The positive and negative electrode materials, electrolyte, etc. of the battery have a significant impact on its self-discharge performance. The use of high-purity raw materials, high-performance electrolytes and electrode materials that have been optimized in design can reduce the side reactions inside the battery, thereby slowing down self-discharge. Some high-end batteries adopt advanced technologies, such as the use of high-quality electrolytes and improved negative electrode designs, which can effectively slow down the self-discharge rate of the battery.
Avoid purchasing inferior products: The self-discharge phenomenon of counterfeit and substandard products will occur more frequently. Therefore, when purchasing e-cigarette batteries, one should choose reputable brands and channels to ensure the quality of the batteries.
Usage habits and maintenance
Avoid the mixture of metal impurities: During the production and use of batteries, the purity of raw materials must be strictly controlled to prevent metal impurities from mixing into the positive and negative electrode materials, electrolyte or other auxiliary materials. These metal impurities may cause micro-short circuits inside the battery, accelerating self-discharge.
Regularly check the battery status: Regularly inspect the voltage, power and appearance condition of the e-cigarette battery. If the battery voltage drops too rapidly or there are other abnormal phenomena, the battery should be dealt with or replaced in a timely manner.
Store the battery properly: When the e-cigarette is not in use, the battery should be removed from the device and stored properly. Avoid storing batteries together with metal objects to prevent metal objects from touching the positive and negative terminals of the battery, which may cause short circuits or accelerate self-discharge.
