Special Issue Information

Dear Colleagues,

The application of carbon materials dates back from the past decades, sighting a speedy scientific importance incited by the innovations in carbon-based nanostructured materials. The most popular nanomaterials of the carbon family to date are fullerenes, CNTs, and graphenes, with dimensions ranging from 0.5 to 100 nm. These carbon-based nanomaterials possess unique and novel properties, such as remarkable mechanical strength, electrical conductivity, and optical, chemical, and thermal properties due to their unique and intriguing size. The prime advantages of the carbon nanomaterials include high surface-area-to-volume ratio and unique thermal, optical, mechanical, and electrical properties to name a few. The characteristic structures of carbon-based nanomaterials promote them to interact with another material for various advanced applications, such as in energy storage and conversion.

The present Special Issue is aimed at presenting the current state-of-the-art in carbon nanostructures for energy storage and conversion to address the various challenging issues researchers are confronted with in this field.

This Special Issue of Nanomaterials invites innovative contributions in terms of research articles, reviews, communications, and letters from around the globe.

Abstract
New three-dimensional (3D) porous electrode concepts are required to overcome limitations in Li-ion batteries in terms of morphology (e.g., shapes, dimensions), mechanical stability (e.g., flexibility, high electroactive mass loadings), and electrochemical performance (e.g., low volumetric energy densities and rate capabilities).

New three-dimensional (3D) porous electrode concepts are required to overcome limitations in Li-ion batteries in terms of morphology (e.g., shapes, dimensions), mechanical stability (e.g., flexibility, high electroactive mass loadings), and electrochemical performance (e.g., low volumetric energy densities and rate capabilities). Here a new electrode concept is introduced based on the direct growth of vertically-aligned carbon nanotubes (VA-CNTs) on embroidered Cu current collectors. The direct growth of VA-CNTs was achieved by plasma-enhanced chemical vapor deposition (PECVD), and there was no application of any post-treatment or cleaning procedure. The electrochemical behavior of the as-grown VA-CNTs was analyzed by charge/discharge cycles at different specific currents and with electrochemical impedance spectroscopy (EIS) measurements. The results were compared with values found in the literature. The as-grown VA-CNTs exhibit higher specific capacities than graphite and pristine VA-CNTs found in the literature. This together with the possibilities that the Cu embroidered structures offer in terms of specific surface area, total surface area, and designs provide a breakthrough in new 3D electrode concepts.

Graphene aerogels (GAs) have attracted extensive interest in diverse fields, owing to their ultrahigh surface area, low density and decent electrical conductivity. However, the undesirable thermal conductivity of GAs may limit their applications in energy storage devices. Here, we report a facile hydrothermal method to modulate both the electrical and thermal properties of GAs by including bulk molybdenum disulfide (MoS2). It was found that MoS2 can help to reduce the size of graphene sheets and improve their dispersion, leading to the uniform porous micro-structure of GAs. The electrical measurement showed that the electrical conductivity of GAs could be decreased by 87% by adding 0.132 vol % of MoS2. On the contrary, the thermal conductivity of GAs could be increased by ~51% by including 0.2 vol % of MoS2. The quantitative investigation demonstrated that the effective medium theories (EMTs) could be applied to predict the thermal conductivity of composite GAs. Our findings indicated that the electrical and thermal properties of GAs can be tuned for the applications in various fields. Full article
