“…[ 315,319 ] In addition, high‐voltage SIBs assembled with ternary solvent‐based electrolytes with high ionic conductivity and low viscosity, such as EC/PC/DMC (0.45/0.45/0.1), EC/PC/DEC (5/3/2), and EC/DMC/DEC (1/1/1), exhibited excellent electrochemical performance. [ 320,321 ] However, there is currently no consensus on the optimal solvent composition. Considering the influence of the solvation structures of different electrolyte components on battery performance, it is necessary to further optimize the solvent design.…”

In recent decades, sodium‐ion batteries (SIBs) have received increasing attention because they offer cost and safety advantages and avoid the challenges related to limited lithium/cobalt/nickel resources and environmental pollution. Because the sodium storage performance and production cost of SIBs are dominated by the cathode performance, developing cathode materials with large‐scale production capacity is the key to achieving commercial applications of SIBs. Therefore, developing host materials with high energy density, long cycling life, low production cost, and high chemical/environmental stability is crucial for implementing advanced SIBs. Among the developed cathode materials for SIBs, O3‐type sodiated transition‐metal oxides have attracted extensive attention owing to their simple synthesis methods, high theoretical specific capacity, and sufficient Na content. However, the relatively large Na‐ion radius leads to sluggish diffusion kinetics and inevitable complex phase transitions during the deintercalation/intercalation process, resulting in poor rate capability and cycling stability. Therefore, this review comprehensively summarizes the research progress and modification strategies for O3‐type cathodes, including the component design, surface modification, and optimization of synthesis methods. This work aims to guide the development of commercial layered oxides and provide technical support for the next generation of energy‐storage systems.

The unique site substitution of Zn in the structure of tetragonal Cu3Zn2Sb2 and the substitution of Cu in the binary InPd3, followed by the formation of Cu5Zn3Sb2 and InPd2Cu has been addressed from fundamental perspectives. First principles total energy calculations, and semi-empirical electronic structure calculations using both the density of states, crystal orbital Hamilton population, and Mulliken population analysis were performed to understand the observed compositional range for both the titled cases and to address the “coloring problem” for the experimentally observed site preferences.

To increase the capacity of battery pack and boost the development of high‐rate performance, a growing number of positive electrode and negative electrode materials and electrolyte materials are being researched and used 10–12 . The production and use of battery packs can cause environmental burdens, and BEVs do not seem to be as environmentally friendly as the public thinks 13 .…”

Vehicle lightweight and carbon neutrality turn out to be the critical goals in developing new energy vehicles. As an important part of electric vehicles, power battery packs have an impact on the environment. In this study, multiple environmental assessment indicators were grouped into a comprehensive index, namely the green characteristic index, and the green characteristic index was used to comprehensively evaluate the environmental impact of 11 kinds of battery packs. This study calculates
