The current application status of molybdenum foil in new energy vehicles
Molybdenum foil has specific applications in new energy vehicles, but its usage scenarios are relatively professional and are limited by cost and technical requirements. At present, its applications are mainly concentrated in fields such as power batteries, heat dissipation of power semiconductors, hydrogen fuel cell technology, sensors and electronic components.
In the field of power batteries, molybdenum foil can be used as an electrode current collector or interface layer material in the research and development of solid-state batteries, avoiding side reactions with the electrolyte and enhancing the battery's cycle life. However, it is still in the laboratory stage at present. In addition, molybdenum foil can also be used as an alternative current collector for high-voltage cathode materials, but due to its high cost, it has not yet been commercially used on a large scale.
In terms of heat dissipation for power semiconductors, metal substrates made by combining molybdenum foil with copper and aluminum can be used for the heat dissipation of IGBT modules, balancing thermal conductivity and a low coefficient of thermal expansion, and reducing thermal stress damage. They are mainly applied in high-end vehicle models. In hydrogen fuel cell technology, molybdenum compounds have been studied as catalyst carriers or alternative materials, but the direct use of moly strip is relatively rare. In the field of sensors and electronic components, molybdenum foil can be used as a substrate for high-temperature sensors and as an electromagnetic shielding layer. However, due to cost factors, its application scope is limited.
Advantages and Bottlenecks
The application of molybdenum strip in new energy vehicles has significant advantages, but it also faces some bottlenecks. Its advantages lie in high-temperature stability, corrosion resistance and low coefficient of thermal expansion. These characteristics enable it to maintain stable performance in extreme environments. However, molybdenum foil is difficult to process, has high brittleness, and its electrical conductivity is slightly inferior to that of copper and aluminum. These factors limit its wide application in new energy vehicles.
Future application trends
Although the application of molybdenum strip in new energy vehicles is relatively niche at present, its future potential cannot be ignored. If breakthroughs are made in solid-state battery or ultra-high voltage battery technology, the application of molybdenum foil in the field of current collectors is expected to be expanded. However, to achieve this goal, it is necessary to reduce costs through composite technologies (such as molybdenum/aluminum laminated foil). In addition, with the rapid development of the new energy vehicle industry, the demand for high-performance materials is constantly increasing. The high-temperature stability and corrosion resistance of molybdenum foil may enable it to play a more important role in specific fields.
To sum up, molybdenum foil is currently a niche high-end material in new energy vehicles, mainly used in specific heat dissipation components, experimental battery technologies, and precision electronic parts. Whether it can be popularized in the future will depend on the commercialization process of solid-state batteries and the cost optimization of molybdenum processing technology. Despite facing cost and technical challenges, molybdenum foil, with its unique advantages, is still expected to play a greater role in the field of new energy vehicles.
