About this collection
The International Conference on Nanomaterials and Advanced Energy Storage Systems (INESS), launched in 2013, has become a leading scientific event in Central Asia for sharing new ideas and discoveries in materials science, energy storage, nanotechnology, and sustainability. Held annually in Kazakhstan and occasionally abroad, INESS brings together researchers from across the world to foster innovation and address the challenges of developing cleaner, more efficient technologies.
This special issue features a selection of exciting research presented at INESS-2024, held at Nazarbayev University in Astana, Kazakhstan. The studies highlight recent advances in next-generation energy storage materials and systems—such as magnetic field effects on lithium-ion cathodes, carbon anodes derived from bio-waste, hydrogel-based electrolytes for hybrid batteries, polyaniline-based supercapacitors enhanced via nanoreactor synthesis, separator-free lithium-sulfur batteries, novel polymer electrolytes, and others. Together, these contributions highlight the latest progress in material innovation and design strategies to improve energy density, cycle stability, and overall performance of modern energy storage technologies.
