Silver coated copper technology is a composite metal material technology, and its core product silver coated copper powder is composed of copper in the core and silver shell covering its surface. A typical silver layer thickness is between 50-200 nanometers, with a silver content (mass ratio) of 5% -30%. In this structure, the copper core plays a role in providing low cost and high conductivity, while the silver shell is crucial in ensuring that the particles resist oxidation during processes such as pulping and printing, while forming good ohmic contact with the battery silicon wafer or TCO film. After sintering, the silver shell acts as a conductive medium, ensuring low contact resistance and reliable adhesion of the electrode, while the copper core reduces material costs while endowing the slurry with certain mechanical strength and thermal stability.
When carrying out the airflow crushing process, it is usually encountered that the moisture absorption of the crushed material significantly increases, and it still absorbs water after drying. How to control it.
Thermal conductive filler is a functional material added to matrix materials such as plastics, rubber, adhesives, etc. to improve their thermal conductivity. They significantly improve the thermal conductivity efficiency of composite materials by forming thermal conduction pathways or networks, and are widely used in electronic device heat dissipation, LED lighting, energy storage, aerospace and other fields.
Single layer graphene is known as the "king of materials" due to its unique two-dimensional honeycomb lattice structure and electronic band characteristics, which exhibit excellent performance in conductivity and thermal conductivity. The following is a detailed analysis of its conductivity and thermal conductivity:
