What is it about?

This is about improving cathodes for sodium-ion batteries. They use a material called NASICON, which is good for conducting ions and staying stable. To make it more cost-effective and eco-friendly, they've mixed vanadium with cheaper elements like iron and manganese. They created a special structure where tiny "pearl-like" chains surround the NASICON material, making it conduct ions better and keeping its shape stable during use. This research has been featured in The Rising Stars of Wiley (Advanced Science) theme collection for the year 2023. The Rising Stars series showcases notable research articles originating from studies led by emerging researchers of international acclaim.

Why is it important?

This research is important because it makes sodium-ion batteries more affordable and environmentally friendly. They've found a way to use cheaper materials and improve the battery's performance. This could lead to better energy storage systems for large-scale applications, which is crucial for renewable energy and electric vehicles.


This study focuses on enhancing the cathodes of sodium-ion batteries. By modifying vanadium with more abundant and less toxic elements, they've created a structure that improves ion conductivity and battery stability. This innovation could have practical implications for more cost-effective and environmentally friendly energy storage solutions.
