2D Nanochannel Interlayer Realizing High-Performance Lithium-Sulfur Batteries.

Commercialization of lithium-sulfur (Li-S) batteries is largely limited by polysulfide shuttling and sluggish kinetics. Herein, 2D nanochannel interlayer composed of alternatively-stacked porous silica nanosheets (PSN) and TiCT-MXene are developed. The 2D nanochannels with selective cation transport characteristics facilitate lithium ion rapid transport, while reject the translocation of polysulfide anions across the separator.

Clay-Originated Two-Dimensional Holey Silica Separator for Dendrite-Free Lithium Metal Anode.

Lithium metal anode is the ultimate choice to obtain next-generation high-energy-density lithium batteries, while the dendritic lithium growth owing to the unstable lithium anode/electrolyte interface largely limits its practical application. Separator is an important component in batteries and separator engineering is believed to be a tractable and effective way to address the above issue. Separators can play the role of ion redistributors to guide the transport of lithium ions and regulate the uniform electrodeposition of Li.

Cation Vacancy-Boosted Lewis Acid-Base Interactions in a Polymer Electrolyte for High-Performance Lithium Metal Batteries.

Polymer electrolytes have gained extensive attention owing to their high flexibility, easy processibility, intrinsic safety, and compatibility with current fabrication technologies. However, their low ionic conductivity and lithium transference number have largely impaired their real application. Herein, novel two-dimensional clay nanosheets with abundant cation vacancies are created and incorporated in a poly(ethylene oxide) (PEO)/poly(vinylidene fluoride-co-hexafluoropropylene)-blended polymer-based electrolyte.

Intestinal epithelial chemokine (C-C motif) ligand 7 overexpression protects against high fat diet-induced obesity and hepatic steatosis in mice.

Background: We previously found that the intestinal epithelial chemokine (C-C motif) ligand 7 (CCL7) plays an important role in the development of toxin-induced acute liver damage. The detailed effects of intestinal epithelial CCL7 on chronic diseases; however, are still unclear. Here, we aimed to investigate the impact of intestinal epithelial CCL7 overexpression on high-fat diet (HFD)-induced obesity and steatohepatitis in mice.
