How to choose thermal conductive silicon film for electric vehicle battery?

Electric vehicle battery research is a very popular industry, many large companies are committed to this field of research, in the production and research process of electric vehicle battery, there is a material that can not be ignored at any time, that is, thermal conductive silica gel sheet. Its use is like his name, the main need to do is heat conduction and heat dissipation, but not all silicon Film is suitable, want to make a good battery needs to be selected properly, so today we have a look: electric vehicle battery thermal conductive silicon film how to choose?



Thermal conductive silica gel sheet



The first is safety and life



In the daily use of electric vehicles, we will encounter many extreme environments, such as high temperature and high corrosion. However, our batteries are not short-term products. After many people buy a battery car, they often need to spend a long time. If there is such a requirement, we should consider the life of any material. Generally speaking, the service life of many battery cars is in In ten years or so, if there is a material such as thermal conductive silica gel chip, it will cause unnecessary loss. Therefore, when choosing silicon film, the first thing to consider is the service life. In order to select enough excellent products, it is a more efficient method to pass the third party's inspection certificate. Generally, there will be a third party's inspection certificate.



The second is thermal conductivity



If a thermal conductive silicon film has no way to play its most valuable role, it is better not to use it and waste materials. In terms of thermal conductivity, we mainly look at the thermal conductivity of a thermal conductive silicon film. However, the greater the coefficient is, the better. It needs to meet a certain range. After many experiments, we determine that the material in the range of 1.0-3.0w / (m · K) is suitable Material is what we need. These parameters can't appear in the product description. Please read it carefully before purchasing, and then we can determine whether it is what we want.

Last consideration: density

This consideration is mainly determined according to the development trend of power battery, because in the current development prospect, lightweight treatment is an irreversible trend, because lightweight treatment will save a lot of energy, which is very helpful for the sustainable development of our battery industry. With this requirement, when selecting various materials, we should choose the light weight one Because the proportion of thermal conductive silica gel sheet in the overall battery is very large, it can be said that most of the weight is provided by him, and his reduction is imminent, so in practical application, we need to choose the density is relatively small.
