Graphitization and Pore Structure Adjustment of Graphene for Energy Storage and Conversion | Bentham Science

摘要

Background: Energy and power density are two key parameters to evaluate the performanceof devices related to energy storage and conversion.Objective: To realize high energy and power density simultaneously, one of the core issues is the exploitationof 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 candidateowing 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, itis highly necessary to consider the graphitization and pore structure simultaneously during graphenepreparation.Review: In this review, we focus on the summary of the latest advances on adjustment methods towardsgraphitization and pore distribution of graphene. Then, the applications to energy storage and conversiondevices are introduced including supercapacitors, lithium-ion batteries and fuel cells. Finally, thechallenges and perspectives are presented, to offer a guideline for the exploration of high-quality porousgraphene-based electrode materials.
