Study on Mechanical Properties and Microstructural Evolution of Composite Copper Foils Following Long-Term Storage

Composite copper foil, a novel negative electrode current collector developed in recent years, can significantly enhance battery safety and energy density while also conserving metallic resources. It is found that after 9 months of long-term storage, the tensile strength of the composite copper foil...
