Today's life is increasingly fast-paced, and this fast-paced brings a variety of problems in various areas have been manifested, take fast charging.

       Fast charging is a relatively traditional concept, which generally refers to a charging method that can bring the battery to or near a fully charged state in a short period of time. There are two types of fast charging technologies for cell phones in the real sense: one is flash charging technology (OPPO's VOOC flash charging technology) and the other is Qualcomm's Quick Charge 2.0 technology.

The essence of both Flash Charge and Qualcomm QuickCharge 2.0 is to increase the voltage/current reaching the battery as much as possible under certain constraints. In the case of a certain battery capacity, according to the energy: W (battery capacity) = power P * time T = voltage U * battery I * time T, so increase the voltage and current, then you can significantly reduce the charging time. So the heat generation in the process of charging is much larger compared to the general charging, and the interface thermal conductive material (thermal conductive silicone film) etc. that solves the heat generation problem can relatively reduce the pressure brought by heat.

As the charging process, a part of the energy generated will become heat, and this part of the heat will be concentrated in the charging device and the body respectively. We can also clearly feel the charger and the body have different degrees of heating phenomenon when charging.

Because of the small size of the charger head, only a single-component insulating thermal conductive silicone or thermal conductive silicone film can be used to conduct heat out. The heat dissipation of the cell phone body is conducted through the heat-conducting silicone film to conduct the heat generated by the CPU or circuit board operation to the graphite sheet or case to conduct
