Method for manufacturing leaf-like CuO nanostructures using in-situ solution precipitation and their lithium ion battery application

摘要

The present invention relates to a method for manufacturing a leaf-like copper oxide nanostructure through an in-situ precipitation method, and specifically, (a) preparing a copper-nickel alloy foil; (b) immersing the copper-nickel foil in an oxalic acid solution containing strong oxidizing agents sodium persulfate and hydrogen peroxide to form leaf-like copper (II) oxalate hydrate (CuC 2 O 4 ·xH 2 O, 0
