Application of Carbon Materials for Lithium Metal Batteries
The use of fossil fuels has made invaluable contributions to the development of human society. However, problems such as resource depletion and environmental pollution force human beings to develop new energy systems and adjust the energy structure. New systems such as wind, hydro, solar, and fuel cells are expected to provide clean and sustainable energy for human society. As an effective way to store and transfer energy, electrochemical energy storage has gradually become an indispensable part of the transformation of energy structure. Since the advent of lithium-ion batteries in the 19th century, they have become an irreplaceable energy storage device in various fields.

Enhance the Solvent Potential of Water
Water is considered the greenest solvent. Nonetheless, the water solubility of natural products is still an incredibly challenging issue. Indeed, it is nearly impossible to solubilize or to extract many natural products properly using solely water due to their low solubility in this solvent.

Electric Double Layer Structure
The electric double layer (EDL) is the most important electrochemical and heterogeneous catalysis region. Because of it, its modeling and investigation are something that can be found in the literature for a long time. However, it is still something in debate, since nowadays a series of new techniques are available for the investigation of this interfacial area at the molecular level by experiments and simulations.

Cyclo- and Polyphosphazenes for Biomedical Applications
Cyclic and polyphosphazenes are extremely interesting and versatile substrates characterized by the presence of -P=N- repeating units. The chlorine atoms on the P atoms in the starting materials can be easily substituted with a variety of organic substituents, thus giving rise to a huge number of new materials for industrial applications. A wide variety of new phosphazene systems, either trimeric or polymeric, have been developed as biomaterials in view of different applications. The materials to apply in biomedical applications should be biocompatible.

The Gel-State Electrolytes in Zinc-Ion Batteries
Zinc-ion batteries (ZIBs) are receiving increasing research attention due to their high energy density, resource abundance, low-cost, intrinsic high-safety properties, and the appropriate plating/stripping voltage. Gel-state electrolytes possess merits of having a wide electrochemical window, good flexibility, superior water retainability, and excellent compatibility with aqueous electrolytes, which makes them potential candidates for flexible batteries. However, the practical applications of ZIBs with gel-state electrolytes still have some issues of water content easily dropping, poor mechanical stability, and the interface problem.
