Layered Oxide Cathode Materials for Lithium-Ion Batteries
This community focuses on the development and stabilization of positive electrode materials, specifically layered oxides and iron phosphates, to improve the energy density and cycle life of rechargeable batteries.
The research is dominated by the engineering of cathode chemistries, with a heavy emphasis on nickel-rich layered oxides and lithium iron phosphate. Recurring themes include enhancing cycling stability through surface coating, doping, and structural modification to prevent degradation. The work addresses specific failure modes such as voltage fade, lattice rotation, and interfacial instability. Methods range from high-entropy doping and single-crystal synthesis to the analysis of cathode–electrolyte interphases. The goal is to create electrode materials that maintain structural integrity and electrochemical performance over repeated charge and discharge cycles.
Lithium research accounts for 7.6% of all tracked lithium studies, representing 18,165 papers within this group. Manganese contributes 2.7% of its total research volume, and cobalt contributes 2.0%.
The community comprises 22,894 papers, published primarily in the Journal of Power Sources, Journal of The Electrochemical Society, and Electrochimica Acta.
Recent work continues to focus on degradation mechanisms in high-nickel and Li-rich cathodes, with specific attention to single-crystal structures, oxygen vacancy stabilization, and interfacial evolution in pouch cells.
