APCVD Graphene-Based Composite Electrodes for Li-Ion Batteries

Abstract

Lithium-ion batteries have numerous advantages, including excellent energy density with high stability. One of the limitations regards the preparation of anode materials at low cost and high safety with good performance. Over the past decade, research has been focused on their improvement as composites, taking advantage of the synergistic effects between the materials. The object of this mini review is to summarize the synthetic strategies of composite electrodes based on graphene that are utilized for lithium-ion chemistries. Emphasis will be given on chemical vapor deposition and how this route can overcome the electrode issues for large-scale deployment.

Graphene Synthesis Techniques and Environmental Applications

“…Since its discovery, graphene has seen an overwhelming response from scientists working in diverse research areas such as engineering, energy storage/management, medicine, electronics, material science, and many other disciplines. Graphene, graphene oxide, reduced graphene oxides, and its composites have been widely adopted as active materials in a wide range of applications including electrochemical energy-storage devices (EESDs) such as supercapacitors and electrochemical batteries [ 116 , 117 , 118 ]. Thanks to their superior characteristics such as excellent thermal, electrical, mechanical, and optical properties, graphene-based materials have also been widely used in electronic applications.…”

Micron-Sized SiOx-Graphite Compound as Anode Materials for Commercializable Lithium-Ion Batteries

“…For example, morphological design providing void space is one of the most well-known strategies, and representative designs include hollow nanoparticles (2725 mAh/g initial capacity and 52% capacity retention after 700 cycles), nanotubes (1780 mAh/g initial capacity and 88% capacity retention after 6000 cycles) and yolk-shells (2833 mAh/g initial capacity and 74% capacity retention after 1000 cycles) [7,[12][13][14][15]. Another familiar strategy is forming a robust buffer matrix with various materials, such as carbon (1950 mAh/g initial capacity and ~100% capacity retention after 100 cycles) and metal oxide materials (~1000 mAh/g initial capacity and ~65% capacity retention after 1000 cycles) [16][17][18][19]. Beyond the physical/chemical material design of Si, Si-graphite-blending-based materials were recently introduced to compensate for the limitation of Si via diluting its content in the anode.…”

Review—Rational Design of Nitrogen-doped Graphene as Anode Material for Lithium-ion Batteries

“…22,23 For these reasons, new materials to be used as anodes in LIBs are continuously investigated. Among the most outstanding options as an alternative to graphite is the use of nano-structured silicon, 24 the renewed interest in metallic lithium, 25 the development of innovative carbon-based materials, [26][27][28] etc. Among these options, the use of graphene in LIBs is the subject of incessant interest due to its extraordinary properties.…”

“…Graphene is a two-dimensional (2D) allotrope of carbon that, compared to graphite, has greater surface area of 2360 m 2 /g, compared to 10 − 20 m 2 /g for graphite, 29 best electrical conductivity, chemical stability, mechanical stability and flexibility. 30,31 For this reason, graphene has been investigated as an anodic material for LIBs, reporting a higher charging capacity compared to graphite, 28,[32][33][34] mainly caused by the adsorption of Li + that can occur on both sides of graphene, so its theoretical specific capacity is two times greater (744 mAh g −1 ) than that of graphite (372 mAh g −1 ). 7,[35][36][37][38] In addition, Li + can also be adsorbed on the edges and on the structural defects of the material, increasing z E-mail: toro@uni.edu.pe the specific capacity of the material.…”
