Sodium-Ion Battery Materials and Electrochemistry
This research community develops the electrode materials and electrolytes required for rechargeable sodium-ion batteries, focusing on high-performance anodes and cathodes for grid-scale energy storage.
The work centers on the synthesis and characterization of hard carbon anodes, layered oxide cathodes, and Prussian blue analogues. Researchers investigate the structural stability of these materials during charge and discharge cycles, with a specific emphasis on optimizing pore structures in carbon to enhance sodium storage capacity and rate capability. The community also explores potassium-ion and lithium-ion variants, utilizing porous carbon frameworks and nitrogen-doped materials to improve electrochemical performance. Key methods include the engineering of closed-pore structures in hard carbon and the development of air-stable layered oxides. These materials are designed to serve as cost-effective alternatives to lithium-ion chemistry for stationary energy applications.
