Sodium and Potassium Ion Battery Electrodes and Electrolytes
This community develops rechargeable battery technologies based on sodium and potassium ions, focusing on the materials and chemistry required to store and release electrical energy.
The research centers on the development of anode and cathode materials for these batteries, with a heavy emphasis on hard carbon and porous carbon structures for sodium storage. Significant work involves layered oxide cathodes and Prussian blue analogues to improve energy density and stability. The community also addresses electrolyte formulations, including ether-based and deep eutectic systems, to enhance safety, wide-temperature tolerance, and anti-oxidation properties. While sodium-ion technology is the primary focus, potassium-ion battery chemistry is a substantial secondary strand, particularly regarding anode design and electrolyte desolvation. The work aims to create high-performance, stable, and industrially viable alternatives to lithium-ion systems.
This community represents 7.1% of all tracked sodium research and 2.9% of potassium research. It also accounts for 3.1% of lithium research, likely due to comparative studies or shared material chemistries.
The community comprises 25,267 papers, published primarily in Chemical Engineering Journal, Journal of Materials Chemistry A, and Journal of Power Sources.
Recent work continues to refine hard carbon pore structures for faster sodium storage and develops electrolytes that improve safety and operational temperature ranges for both sodium and potassium systems.
