Solid electrolytes are highly important materials for improving safety, energy density, and reversibility of electrochemical storage batteries. However, it is a challenge to modulate the coordination structure conducting ions, which limits improvement ionic conductivity hampers further development practical solid electrolytes. Here, we present skeleton-retained cationic exchange approach produce high-performance electrolyte Li 3 Zr 2 Si PO 12 stemming from NASICON-type superionic conductor...
Air sensitivity remains a substantial barrier to the commercialization of sodium (Na)-layered oxides (NLOs). This problem has puzzled community for decades because complexity interactions between air components and their impact on both bulk surfaces NLOs. We show here that water vapor plays pivotal role in initiating destructive acid oxidative degradations NLOs only when coupled with carbon dioxide or oxygen, respectively. Quantification analysis revealed reducing defined cation competition...
A novel room-temperature molten salt electrolyte based on urea and lithium bis(trifluoromethane sulfone)imide (LiN(SO2CF3)2, LiTFSI) has been synthesized characterized by differential scanning calorimetry (DSC), Raman spectroscopy, ac impedance, cyclic voltammetry. This appears as a liquid at room temperature, though it is composed of two solids. DSC shows that its eutectic temperature about −37.60 °C. Strong interactions between the components observed spectroscopy weaken bonding anions...
Sulfide solid electrolytes (SEs) with high ionic conductivity and facile formability provide great promise to construct energy density safe all-solid-state batteries (ASSBs). However, the poor air stability of sulfide feedstock SEs makes synthesis, storage, postprocessing materials in a dry inert-gas atmosphere, which increases complexity cost production process. Here, boron-assisted sulfurization synthesis method is reported for preparing various from oxide raw materials, including Li4SnS4,...
Combining high-throughput first-principles calculations and experimental measurements, we have identified a novel family of fast lithium-ion chalcogenide conductors in Li$_2$BMQ$_4$ (2114, B = Ca, Sr Ba; M Si, Ge Sn; Q O, S Se) systems. Our demonstrate that most the thermodynamically kinetically stable sulfides selenides this new system exhibit ultralow Li$^+$ ion migration activation energy (0.16 eV ~ 0.56 eV) considerable bandgaps varying between 2 3.5 eV. We successfully synthesized...
