Carbons: Multi-functional Energy Storage Materials
Energy Storage Materials in 2016. In 2015, the world market for electric vehicles has significantly increased. In particular, that in China has more than doubled due to the environmental protection legislation and awareness in metropolitan areas and the progress in battery technology. Therefore, the research and development of energy storage materials and devices has become even more important. Following the publication of the first issue of Energy Storage Materials in November 2015, which contained 16 articles with high scientific significance, we hope to continue to present our readers with the latest and most exciting discoveries in the fields of energy storage and conversion materials and devices in 2016. As editors, we will do our best to guarantee prompt and fair review and a rapid decision to authors on the suitability of their submissions, and our publishing staff at Elsevier will also do their best to rapidly publish accepted manuscripts online for fast and wide circulation in the community. The goal of our journal is to publish the top discoveries in the field that have a high impact. In this coming year of 2016, our focus will be on, but not limited to, materials and related devices for the storage and conversion of energy in different forms. Energy storage by an electrochemical route, in a battery, cell or capacitor, has been paid the most attention and has been developed very rapidly in recent years. We believe this will have a significant influence on science and technology in the near future. In these devices, carbon materials of various forms are almost inevitably used. Here in the On Energy Editorial for this issue, we emphasize and highlight carbon materials with different features and functionalities used in different applications or devices (Fig. 1) [1–3]. The first of these, especially for carbon nanotubes and graphene, is their mechanical flexibility. Novel designs of configurations and devices have been achieved using this property. For example, a continuous film or yarn can been drawn from vertically-grown carbon nanotubes and then wrapped around an anodic-oxidized titanium wire to form a bendable all-solid-state micro-supercapacitor [4]. This interesting wire-shaped device can be woven into various textiles and connected in series or parallel to meet different energy demands. In another case, flexible graphene nanosheets were used as a support for Fe3O4 as anode material in a Li ion battery. The good conductivity, flexibility and unique pore structure of graphene facilitate electron transport and stabilize the active Fe3O4. As a result, a good and reversible performance for Li ion storage was obtained with this material [5]. Another important feature of carbon materials is the ease with which they can be made with different microstructures. Pores with desired shapes and sizes can be introduced into carbons, with or without templates, to fulfill the special requirements of various applications. For a supercapacitor, an ordered mesoporous carbon is especially desirable because of its high surface area and tubular pore structure [6]. By suitably decorating its pore surface, this
material has shown a high capacity, good stability and high rate capability as a Li ion supercapacitor. In addition, the crystallinity of carbon materials can also be tuned by selecting appropriate precursors and processing. An amorphous carbon has been produced by pyrolyzing a mixture of low-cost pitch and phenolic resin, and used as the anode material in a Na ion battery [7]. Its graphitization degree can be adjusted by changing the ratio of the two precursors and/or the pyrolysis temperature. By carefully tuning these parameters to meet the requirements of Na ion storage, this low-cost amorphous carbon shows excellent electrochemical performance in Na ion batteries, and provides a new approach for the development of low-cost energy storage systems. The third interesting characteristic of carbon materials is their high chemical versatility. They can be doped or decorated on the basal plane and/or on the plane edges. These hetero-species have been incorporated into carbon either by post treatment or in-situ synthesis [8,9]. The dopants have been controlled by precisely adjusting the synthesis conditions, and a deep understanding of the relationship between the materials' chemistry and the corresponding performance has been obtained. Increasing attention has been paid to carbons with specific features and functionalities. In addition to original research studies, we have also selected three comprehensive review articles, covering the emerging research hotspots in both materials and devices [1–3]. We hope they will bring new insights and inspiration to boost new ideas in these areas. Last but not least, we would like to take this opportunity to express our sincere wishes for a happy and prosperous New Year as well as our great appreciation to all our readers, authors,
