Advancing lithium-ion battery technology with heteroatom doped graphene anodes

Abstract

Graphene, with its exceptional and unrivaled properties, has solidified its position as the leading contender for the next generation of lithium-ion batteries. However, the trajectory of progress for graphene-based lithium-ion batteries hinges entirely upon a profound comprehension of its underlying structural intricacies and the avenues for enhancement made possible through heteroatom doping. This chapter serves as a concise exploration of the concept of heteroatom doping in graphene—a paradigm-shifting approach that reshapes graphene’s electronic attributes, conductivity, and structural framework alongside its far-reaching applications in the realm of lithium-ion batteries. The contiguous three-dimensional graphene matrix, thoughtfully integrated, emerges as a pivotal element in the optimization of ion and electron transport within the electrode materials. The judicious introduction of heteroatoms, in this context, further augments these intrinsic properties, thus fortifying electrode stability to an even greater degree. Within the confines of this chapter, we summarized recent advancements in the utilization of heteroatom-doped graphene for lithium-ion batteries, illuminating the exciting developments in this dynamic field.
