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.

Abstract

Wadsley Defects Defect-rich shear structures fill space with a variety of different block sizes. These Wadsley defects can be associated with additional cation disorder and vacancies where the effect of each upon lithium-ion transport was studied. The resulting insights explained the three-times enhancement found in the diffusivity of a defect-rich sample.
