AbstractCrystallography is a powerful descriptor of the atomic structure of solid-state matter and can be applied to analyse the phenomena present in functional materials. Especially for ion diffusion – one of the main processes found in electrochemical energy storage materials – crystallography can describe and evaluate the elementary steps for the hopping of mobile species from one crystallographic site to another. By translating this knowledge into parameters and search for similar numbers in other materials, promising compounds for future energy storage materials can be identified. Large crystal structure databases like the ICSD, CSD, and PCD have accumulated millions of measured crystal structures and thus represent valuable sources for future data mining and big-data approaches. In this work we want to present, on the one hand, crystallographic approaches based on geometric and crystal-chemical descriptors that can be easily applied to very large databases. On the other hand, we want to show methodologies based onab initioand electronic modelling which can simulate the structure features more realistically, incorporating also dynamic processes. Their theoretical background, applicability, and selected examples are presented.

Renewable Energy Storage

Sustainable biomass has attracted a great attention in developing green renewable energy storage devices (e.g., supercapacitors) with low-cost, flexible and lightweight characteristics. Therefore, cellulose has been considered as a suitable candidate to meet the requirements of sustainable energy storage devices due to their most abundant nature, renewability, hydrophilicity, and biodegradability. Particularly, cellulose-derived nanostructures (CNS) are more promising due to their low-density, high surface area, high aspect ratio, and excellent mechanical properties. Recently, various research activities based on CNS and/or various conductive materials have been performed for supercapacitors. In addition, CNS-derived carbon nanofibers prepared by carbonization have also drawn considerable scientific interest because of their high conductivity and rational electrochemical properties. Therefore, CNS or carbonized-CNS based functional materials provide ample opportunities in structure and design engineering approaches for sustainable energy storage devices. In this review, we first provide the introduction and then discuss the fundamentals and technologies of supercapacitors and utilized materials (including cellulose). Next, the efficacy of CNS or carbonized-CNS based materials is discussed. Further, various types of CNS are described and compared. Then, the efficacy of these CNS or carbonized-CNS based materials in developing sustainable energy storage devices is highlighted. Finally, the conclusion and future perspectives are briefly conferred.

The Impact

Several polymeric thermal energy storage composites of high density polyethylene and polypropylene with two commercial paraffin waxes (PCM) P27 and P31 were prepared. The compounds were further reinforced with carbon fibers and carbon nanotubes to improve their thermal conductivity and heat transfer efficiency. The impact penetration behavior, service temperature and solvent resistance of the composites were improved by the addition of SEBS. DSC, optical microscopy, SEM, impact penetration and time–temperature history studies of the materials were done to determine the structure and thermal properties of these composites. The paraffins provide energy storage effect by solid–liquid phase change. The polymers encapsulate the paraffins so that the fluid motion of the PCMs is reduced during an application. The composites prepared were used for the construction of a small prototype swimming pool (laboratory scale). The time–temperature history of the composites, water in the container with and without energy storage materials and the environment was recorded. It was found that the composites significantly prolonged the cooling down time for water in the PCM pool. The difference between the cooling down temperature of water in a container with and without PCM composite was almost 4 hours. Moreover a computer program in C++ was written to solve the heat flow equations for the calculation of theoretical temperature–time curves.
