Abstract

Background: Energy and power density are two key parameters to evaluate the performance of devices related to energy storage and conversion.

Objective: To realize high energy and power density simultaneously, one of the core issues is the exploitation of high-efficiency electrode materials which could expose plentiful accessible active sites, promote electron transfer and accelerate ion transport.

Strategy: High-quality porous graphene, porous graphene with good graphitization, is a promising candidate owing to its large accessible surface area, high conductivity and suitable pore distribution. However, pore-drilling can introduce defects which would reduce the graphitization inevitably. Therefore, it is highly necessary to consider the graphitization and pore structure simultaneously during graphene preparation.

Review: In this review, we focus on the summary of the latest advances on adjustment methods towards graphitization and pore distribution of graphene. Then, the applications to energy storage and conversion devices are introduced including supercapacitors, lithium-ion batteries and fuel cells. Finally, the challenges and perspectives are presented, to offer a guideline for the exploration of high-quality porous graphene-based electrode materials.

Keywords: Energy storage and conversion, fuel cells, graphene, graphitization, lithium-ion batteries, porous structure, supercapacitors.
