Copper Foil (Anode Current Collector)

Product Overview

Electrolytic copper foil is widely used as the current collector for the anode of lithium-ion batteries. It provides excellent electrical conductivity, mechanical flexibility, and stable electrochemical performance during battery cycling.

In laboratory battery research, copper foil is typically used as the substrate for coating graphite, silicon, or other anode materials. Due to its stable structure and mature manufacturing process, it remains one of the most commonly used current collector materials in battery R&D and pilot production.
