The lithium ion battery is widely applied to the power battery fields of automobiles, electric bicycles and the like, the energy storage fields of electric power grids, industrial energy storage, household energy storage, communication energy storage and the like, and the 3C digital fields of smart phones, notebook computers, intelligent wearing equipment, mobile power supplies and the like.
The lithium battery can generate chemical reaction in the battery during discharging, and a large amount of heat energy is generated, so that the temperature of an electric core in the battery is increased, and the temperature can be felt when the lithium battery is touched by hands, which is a common phenomenon in most lithium batteries. The battery can be aged due to frequent heating of the battery core, and if the internal air is severely expanded for a long time, the battery is outwards protruded, and the battery can be seriously burnt. Therefore, in order to ensure that heat is not generated between the cells due to heat transfer, a buffer heat insulating pad is often sandwiched between the two cells. However, the prior buffer heat insulation pad is insulated by aerogel, and most of the aerogel is coated and packaged by PET film, and the PET film can be directly melted at 120 ℃, so after the battery cell works for a long time, the PET film can be melted by the heat emitted by the battery cell, and after the aerogel has less packaging film, the aerogel is easy to crack and leak, so that the service life of the buffer heat insulation pad is shortened. Accordingly, there is a need for improvements over existing cushioning insulation pads.
