Special Issue Information
Dear Colleagues,
With the rapid depletion of fossil fuels, along with the serious pollution of the environment, the development and utilization of clean and sustainable energy have attracted a lot of attention. As an important component of energy storage technology, electrochemical energy storage devices, such as supercapacitors and batteries, have become increasingly important. However, these energy storage devices suffer from unsatisfactory energy density and relatively poor rate performances. Designing and developing novel electrodes with the desired structures is an effective strategy to address these issues. Based on the charge–discharge mechanism and ion/electron transport kinetics, an ordered structure with abundant straight channels and a large surface area is the decisive factor that determines the performance of an energy storage device because such kind of structures could promote the ion diffusion capacity and energy storage processes. Carbon materials encompass excellent electrical conductivity, chemical stability, and large surface areas, which makes them attractive as electrodes for high-performance energy storage devices. Among them, graphene and carbon nanotubes (CNTs) provide the widest diversity and versatility in rationally designing the desired electrode. The vertically aligned structure and well-defined tube spacing in CNT arrays could provide abundant straight electrolyte-accessible channels. Graphene sheets can carry large current densities and fast electron transfer processes when used as electrodes due to their high conductivity and large contact surface areas. Moreover, the bonding scheme for the vertical CNT array and parallel graphene could realize a synergistic effect and further extend the diversity of carbon-based micro/macrostructures. Additionally, the easy functionalization property could endow the graphene and CNT with high catalytic abilities. Designing multidimensional and multifunctional carbon material-based electrodes provide infinite possibilities for developing novel energy conversion and storage devices.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Crystals is an international peer-reviewed open access monthly journal published by MDPI.
