High‐Density Monolith of N‐Doped Holey Graphene for Ultrahigh Volumetric Capacity of Li‐Ion Batteries

Abstract

A convenient and scalable strategy to prepare N-doped holey-graphene monolith (NHGM) electrodes with high volumetric capacity for lithium-ion batteries is shown. The holey-graphene sheets are an excellent material featuring a high Li-ion storage, unimpeded ion channels, and high volumetric capacity. NHGM possesses the advantageous features of a high packing density, efficient ion channels, and favorable mass transport, resulting in a high volumetric capacity, high rate capability, and excellent stability as anode material for lithium-ion batteries.
