A new 3D metallic carbon allotrope composed of penta-graphene nanoribbons as a high-performance anode material for sodium-ion batteries

Abstract

We propose a new 3D metallic carbon allotrope constructed by penta-graphene nanoribbons as promising anode material for sodium-ion batteries, which expands the family of pentagon-based carbon allotropes from 2D penta-graphene to 3D metallic material.
