Abstract
- Lithium ion copper foil is prone to oxidation and discoloration on the surface during production, storage-transportation, and use, which directly affects the product yield, reliability, service life and adhesion of lithium batteries. This requires copper foil to have good anti oxidation performance. In this paper, the changes in surface morphology and oxygen content of the copper foil under different soaking and micro electroplating process conditions were studied using characterization methods such as SEM and ED AX. The impact of soaking and micro plating processes on the surface of copper foil surface anti oxidation performance. The results show that when the current density is 5 A/dm², the plating time is 10 s, the chromic anhydride concentration is 0. 5 g/L, and the glucose concentration is 1. 5 g/L. After the copper foil is baked at high temperature, there is no discoloration on the surface, and the anti oxidant performance is better. [ABSTRACT FROM AUTHOR]
