New three-dimensional porous electrode concept: vertically-aligned carbon nanotubes directly grown on embroidered copper structures

New three-dimensional (3D) porous electrode concepts are required to overcome limitations in Li-ion batteries in terms of morphology (e.g., shapes, dimensions), mechanical stability (e.g., flexibility, high electroactive mass loadings), and electrochemical performance (e.g., low volumetric energy de...
