What is Sodium Battery Current Collector?
Sodium Battery Current Collector is a critical structural component used in sodium ion batteries, designed to collect current for external output while simultaneously serving as a carrier for positive and negative electrode materials. The performance of current collector materials directly affects the Coulombic efficiency, rate performance, and cycling stability of the battery. Key material types include aluminum foil and composite aluminum foil, with aluminum foil emerging as the preferred negative electrode current collector owing to sodium's electrochemical compatibility-a notable distinction from lithium-ion systems where copper foil is conventionally used.
Sodium resources are abundant, accounting for approximately 2.74% of the earth's crust, and the substitution of aluminum foil for copper foil as the negative electrode current collector reduces material costs by 30%–40%-a significant competitive advantage. Furthermore, advancements such as surface coating of aluminum foil with carbon nanotubes and graphene have reduced contact resistance by 20%–30%.
