Sodium and Potassium Ion Battery Materials
This community develops electrode materials and electrolytes for rechargeable batteries that use sodium or potassium ions instead of lithium, primarily for grid-scale energy storage and applications where cost and resource availability are critical constraints.
The research focuses heavily on hard carbon anodes, including the engineering of closed pores to enhance capacity and rate capability. On the cathode side, work centers on layered oxides, Prussian blue analogues, and mixed metal phosphates, with significant attention to structural stability and air sensitivity. A substantial portion of the literature addresses electrolyte chemistry, including ether-based systems and solid electrolyte interphase mechanisms, to improve cycling stability and safety. While the primary focus is sodium, a distinct strand of research applies similar material design principles to potassium-ion systems, particularly regarding anode materials and cathode doping strategies.
The largest share of this community's output is found in sodium research, accounting for 38.2% of all sodium research and comprising 11,654 papers within this group. Potassium research represents the second largest share at 13.8%, with 3,439 papers.
The community comprises 19,170 papers, with the highest publication volumes in Chemical Engineering Journal, Journal of Power Sources, and Journal of Materials Chemistry A.
Recent work continues to refine hard carbon pore structures for faster sodium storage, develop sulfur-doped porous carbons, and investigate electrolyte additives to improve oxidation stability in full-cell configurations.
