Intimate Interaction of TFSI− Anions with MoO3−x Oxygen Vacancies Boost Ionic Conductivity of Cathode-Supported Solid Polymer Electrolyte

Actual operation of SSB

Schematic illustration of ion dissociation in the presence of MNBs.

MoO3−x nanobelts (MNBs) were used a passive nanofillers in a PEO/LiTFSI matrix to enhance the ionic conductivity of solid polymer electrolyte.
The O2 vacancies on the MNBs surface act as Lewis acid sites and dissociate the LiTFSI salt into Li+ cation and TFSI- anions. This phenomenon help to increase the ionic conductivity of the polymer matrix.

Capillary-Induced Self-Crumpled and Sulfur-Deficient MoS2 Nanosheets Inhibit Polysulfide Cycling in Lithium-Sulfur Batteries

Specially designed 3D crumpled MoS2 was utilized as a shielding layer to suppress the migration of Li-Polysulfides.
The strained sulfur vacancies on the MoS2 surface initiate the adsorption and reutilization of LiPSs during battery cycling.

Li Dendrite Growth

Ball Milling Method

Spray Coating Technique

Oxygen-Enriched α-MoO3–x Nanobelts (MNBs) were utilized to suppress the formation of Li dendrites on Li metal anode.
MNBs can shorten the diffusion length of Li with a large surface area and a high number of edges and corners.
The MNBs provide sufficient diffusion pathways for the Li+ ions to diffuse during cycling, which decreases the electrode's interfacial resistance.
