About this book

This book focuses on the development of high-performance carbon electrodes for sodium ion batteries (SIBs). By proposing folded-graphene as the high-density cathode with excellent rate capability, it provides insight into the interplay between oxygen functional groups and folded texture. It also highlights the superiority of ether electrolytes matching with carbon anodes, which are shown to deliver largely improved electrochemical performance. The achievements presented offer a valuable contribution to the carbon-based electrodes in SIBs.

Chapter 1. Introduction
Abstract
Energy production and storage has been one of the hottest scientific topics in recent years. With the irreversible consumption of fossil fuel resources and increasingly severe environmental problems, renewable and clean energy source such as solar and wind energy are rapidly developing. However, some challenges are accompanied especially on how to smoothly and safely integrate the intermittent renewable energy into the grid. The application of a proper large-scale energy storage system will be extremely important and urgently needed. Among diverse potential energy storage technologies, electrochemical secondary batteries are competitive due to the advantages such as high energy conversion efficiency and simple maintenance. The major parameters for stationary batteries are low cost, high safety and long life span.

Chapter 3. Folded-Graphene as an Ultrafast Cathode Material
Abstract
For the cathode materials in SIBs, two major types of inorganic materials are dominating, namely layered transition-metal oxides and poly-anionic compounds. They can deliver a relatively high reversible capacity between 100 and 150 mA h g−1, along with a good cycling stability. However, compared with lithium, the larger ion size of sodium usually induces severe structural distortion to electrode and inferior charge storage kinetics due to the limited diffusion capability.

Chapter 4. The Interplay of Oxygen Functional Groups and Folded Texture in Folded-Graphene Cathode
Abstract
As discussed in last chapter, we have originally reported a novel approach toward ultrafast high-volumetric sodium storage of folded-graphene electrodes through surface-induced redox reactions, which successfully preserved the capacitive reactivity in an intensively densified texture and dramatically improve the volumetric efficiency of energy storage, indicating a prospective avenue toward compact electrochemical energy storage. Simply by assembling graphene oxide nanosheets into a hydrogel and controlling the evaporation process, densified graphene electrodes were prepared and excellent long-term stability and rate capability were also witnessed, which were quite competitive among related reports. Whereas, if we want to strive for further advancement, a critical question has to be thoroughly understood, namely what is the interplay of oxygen functional groups and folded texture in densified graphene electrodes.

Chapter 5. Achieving Efficient Sodium Storage on Carbon Anodes with Ether-Derived Solid Electrolyte Interphase (SEI)
Abstract
The development of promising anode materials is also a critical challenge for the application of SIBs, since graphite unfortunately delivered limited capacity around 50 mA h g−1 in commonly used ester-based electrolytes. Carbon materials are still the most widely accepted anode choice, due to their advantages such as low cost and abundance, environmental benignity and facile production, high electrochemical activity, controllable microstructure and surface chemistry.

Chapter 6. Evolution of the Electrochemical Interface with Ether-Based Electrolytes
Abstract
As previously introduced and discussed, in order to improve the electrochemical performance of present anode materials, especially for carbon materials, modifying the electrolyte is an important and effective approach.

Chapter 7. Conclusion and Perspective
Abstract
This thesis focuses on the development and modification of novel carbon-based electrodes for SIBs. Through the self-assembly of graphene oxide and following effective three dimensional densification, highly folded-graphene with high density can be prepared to address the critical obstacle of ultra-low density for pseudo-capacitive cathode. Besides, the interfacial electrochemistry of practical carbon anodes has been regulated by an ether-based electrolyte, dramatically addressing the critical obstacle of ultra-low ICE for carbon anodes. Above research progresses are of vital importance for the practical application of SIBs.
