It is understood that 3M has always tap the potential of various new materials during the production of batteries. Based on the research results of new materials, 3M provides a perfect, mature battery power program for the electric vehicle market, and has successfully developed a non-solubility nanoscale coating process for electric vehicle battery current collectors. The technology increases the electrical conductivity and capacity performance of the current collector, which has greatly narrowed the battery volume, which can provide strong engine power for electric vehicles, and successfully solve the problem of high volume and weak conductivity in electric vehicle battery.
3M also solves the battery in the event of too high or low in the case, and develops a new battery packing heat management program, by air, liquid or phase change material is medium heat Management technology, enhances the overall performance of the battery, extending the life of electric vehicle batteries.
