Abstract

Abstract: Paper is emerging as a promising flexible, high surface‐area substrate for various new applications such as printed electronics, energy storage, and paper‐based diagnostics. Many applications, however, require paper that reaches metallic conductivity levels, ideally at low cost. Here, an aqueous electroless copper‐plating method is presented, which forms a conducting thin film of fused copper nanoparticles on the surface of the cellulose fibers. This paper can be used as a current collector for anodes of lithium‐ion batteries. Owing to the porous structure and the large surface area of cellulose fibers, the copper‐plated paper‐based half‐cell of the lithium‐ion battery exhibits excellent rate performance and cycling stability, and even outperforms commercially available planar copper foil‐based anode at ultra‐high charge/discharge rates of 100 C and 200 C. This mechanically robust metallic‐paper composite has promising applications as the current collector for light‐weight, flexible, and foldable paper‐based 3D Li‐ion battery anodes. Abstract : A copper‐plated paper‐based half‐cell of Li‐ion battery (LIB) exhibits excellent rate performance and cycling stability. The paper‐based anode outperforms planar copper foil‐based anodes at ultra‐high charge/discharge rates, benefitting from the porous structure and the large surface area of cellulose fibers. This mechanically robust metallic paper composite has promising application for light‐weight and foldable 3D LIB anodes.
