Summary
A high-efficiency, long-cycle-life, and high-specific-capacity Rechargeable Energy Storage Systems is indispensable for meeting the growing energy demands of modern technologies, including mobile communications, portable electronics, and electric vehicles. This Special Issue focuses on the synthesis and characterization of nanostructured electrode materials for next-generation Energy Storage Systems.
The development of nanostructured electrode materials offers a promising strategy for enhancing the electrochemical performance of lithium-ion batteries as one of Rechargeable Energy Storage Systems. Their implementation can significantly increase energy density, enabling smaller and lighter battery packs to deliver the same or even greater power output. Owing to their large specific surface area, short lithium-ion diffusion pathways, and improved electrode–electrolyte contact, nanostructured materials facilitate faster Li-ion insertion and extraction kinetics. Consequently, they contribute to higher power density, improved rate capability, enhanced specific capacity, and prolonged cycling stability. These advantages make nanotechnology a key enabler in the advancement of high-performance, durable, and energy-efficient lithium-ion batteries.
The areas that are particularly considered for publication include, but are not limited to, the following:
• Synthesis and design of novel nanostructured anode and cathode materials for lithium-ion batteries
• Nanostructured materials for sodium-ion, potassium-ion, and multivalent-ion batteries
•Advanced characterization techniques for understanding nanoscale electrochemical mechanisms
• Theoretical modeling and simulation of nanostructured electrode behavior
• Interface engineering and electrode–electrolyte interactions at the nanoscale
• Nanostructured materials for solid-state batteries and flexible energy storage devices
• Scalable synthesis methods and commercialization pathways for nanomaterials
•Degradation mechanisms and strategies for extending cycle life in nanostructured electrodes
• Hybrid and composite nanostructures for enhanced energy and power density
•Nanostructured materials for supercapacitors and beyond-lithium energy storage systems
• In-situ and operando studies of nanostructured electrode dynamics
• Safety, sustainability, and lifecycle assessment of nanomaterial-based batteries
We welcome original research articles, comprehensive reviews, and critical perspectives that advance the fundamental understanding and practical application of nanostructured electrode materials for next-generation energy storage technologies.
