Role of Wadsley Defects and Cation Disorder to Enhance MoNb 12 O 33 Diffusion (Adv. Energy Mater. 12/2026)

Key Points

• The study aims to understand how Wadsley defects and cation disorder affect lithium-ion diffusion in MoNb12O33.
• Analyzed defect-rich shear structures in MoNb12O33.
• Examined the relationship between cation disorder and lithium-ion transport.
• Measured diffusivity of various samples, comparing defect-rich and standard states.
• Defect-rich MoNb12O33 exhibited three times the diffusivity compared to less defective samples.
• Wadsley defects contributed significantly to enhanced lithium-ion transport.
• Cation disorder also played a crucial role in increasing diffusivity.
