With the significant growth and development of battery pack technologies, manufacturers of electric vehicles (EVs) are placing an increased emphasis on pack design optimization seeking lighter weight and more compact solutions to gain additional energy density and reduce cost. In our whitepaper, we will discuss our evaluation of the dielectric protection, process application advantages and disadvantages, edge coverage, adhesion properties, and environmental resistance of each of these categories of materials.
Test results presented will include hi-pot breakdown voltage before & after environmental exposures (i.e. 85/85 and thermal shock), cross-hatch & lap-shear adhesion, thickness measurements on edges & corner radius, and thermal conductivity.
