Synthesis and characterization of argyrodite solid electrolytes for all-solid-state Li-ion batteries

Li₆PS₅X (X = Cl, Br, I) argyrodites possess high ionic conductivity but with rather scattered values due to various processing conditions. In this work, Li₆PS₅X solid electrolytes were prepared by solid-state sintering or mechanical alloying and optimized with or without excess Li₂S....

Synthesis of severe lattice distorted MoS₂ coupled with hetero-bonds as anode for superior lithium-ion batteries

Exploration of advanced anode materials is a highly relevant research topic for next generation lithium-ion batteries. Here, we report severe lattice distorted MoS₂ nanosheets with a flower-like morphology prepared with PEG400 as additive, which acts not only as surfactant but importantly, also as reactant. Notably, in the absence...

Interface-Engineered Li₇La₃Zr₂O₁₂-Based Garnet Solid Electrolytes with Suppressed Li-Dendrite Formation and Enhanced Electrochemical Performance

High grain-boundary resistance, Li-dendrite formation, and electrode/Li interfacial resistance are three major issues facing garnet-based solid electrolytes. Herein, interfacial architecture engineering by incorporating 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl) imide (BMP-TFSI) ionic liquid into a garnet oxide is proposed....
