| Abstract Scope |
The widespread adoption of electric vehicles (EVs) is crucial for reducing carbon emissions and protecting the environment, but it also presents technical challenges. The conductivity of coatings on charging sockets and terminals directly affects charging efficiency— higher conductivity results in lower energy consumption during charging. The mechanical strength and wear resistance of these coatings determine their long-term reliability. Silver has the highest conductivity among metals, but its poor mechanical strength causes reliability issues with frequent insertion/withdrawal cycles. This study employs unique cyanide-free electroplating silver nanotwins to enhance strength while maintaining high conductivity. Additionally, the graphene with its self-lubricating, high-strength, and conductive properties, was co-deposited to bring in the dispersion strengthening. And then discuss the impact of co-deposited graphene on silver’s microstructure, hardness, and wear resistance. This approach ensures that the silver coating on charging terminals combines high conductivity with enhanced mechanical strength to meet future usage demands. |
