简体中文 Lithium battery heating sheet is an electric heating device that mainly uses the principle of resistive heating to convert electrical energy into thermal energy. It is generally made of conductive materials (such as conductive aluminum foil, conductive graphite, etc.), which generate heat through the internal resistance of the conductive material and transfer the heat to the lithium battery to increase the temperature of the lithium battery.
Its main purpose is to improve the performance stability and extend the service life of the lithium battery by increasing its temperature. The following is a detailed explanation of lithium battery insulation heating sheet:
Improve battery performance
Under low temperature environment, the electrolyte inside the lithium battery will become viscous and the ion conductivity will deteriorate, resulting in a decrease in the battery’s charge and discharge performance. Specifically, low temperature will cause the battery capacity to decrease, the internal resistance to increase, the charging speed to slow down, and even the situation of being unable to charge or discharge may occur.
Lithium battery heating sheet generates heat, increases the temperature of the battery, and restores the normal fluidity of the electrolyte, thereby improving the battery’s charge and discharge performance. In this way, the device can also maintain stable battery performance in a low temperature environment to ensure that the use is not affected.
Extend battery life
Low temperature shortens life. Long-term use of lithium batteries in low temperature environments will accelerate the aging process of the battery and shorten the battery life. Using lithium battery insulation heating sheets can ensure that the battery works within the appropriate temperature range and avoid being in a low temperature state for a long time, thereby extending the battery life.
Improve safety
At extremely low temperatures, lithium batteries may have safety hazards such as uneven charging and internal short circuits, and in severe cases may even cause fires or explosions. Increasing the temperature of the battery through the heating sheet can prevent the occurrence of these safety hazards and ensure the safe operation of the equipment.
Improve user experience
In the cold winter, due to the decline in battery performance, the device may take longer to start or charge. Using lithium battery insulation heating sheets can speed up the charging and discharging of the battery, reduce the user’s waiting time, and improve the user experience.
Dealing with extreme weather
In extremely cold areas or extreme weather conditions, traditional lead-acid batteries may not be able to meet the needs of electrical equipment. Although lithium batteries have better performance, they will also be affected at low temperatures. To meet the challenges of extreme weather, lithium battery insulation heating sheets provide an effective solution for equipment to ensure normal operation under extreme weather conditions.
When assembling battery packs, MK factory configures heating plates according to different customer usage environments to ensure the performance of lithium batteries and improve the possibility of using lithium batteries in cold environments.
