نویسندگان
چکیده
Li 6.4 Ga 0.2 La 3 Zr 2 O 12 can be reduced by Li, which results in leaching out of the garnet structure to form Li–Ga alloy. The penetrated alloy short-circuit battery when Ga-substituted LLZO is used as a solid electrolyte.

Toward garnet electrolyte–based Li metal batteries: An ultrathin, highly effective, artificial solid-state electrolyte/metallic Li interface
Solid-state batteries are a promising option toward high energy and power densities due to the use of lithium (Li) metal as an anode. Among all solid electrolyte materials ranging from sulfides to oxides and oxynitrides, cubic garnet-type Li7La3Zr2O12 (LLZO) ceramic electrolytes are superior candidates because of their high ionic conductivity (10-3 to 10-4 S/cm) and good stability against Li me...
متن کاملComputational Study of Ga NMR Shielding in Metallic Gallides
We present first-principles calculations of the isotropic NMR Ga shielding in metallic MGa2 with M = Ca, Sr, Ba and MGa4 with M = Na, Ca, Sr and Ba. We show that the experimentally observed trend of Ga NMR shifts is as expected driven mainly by the spin part of the response, but the orbital contribution must not be neglected. For all analyzed compounds the spin contact term constitute the major...
متن کاملPhysical and Magnetic Properties of Calcium-Substituted Li-Zn Ferrite
The effect of Ca-substitution on the physical and magnetic properties of Li0.3-0.5xZn0.4CaxFe2.3-0.5xO4 ferrites (x = 0.0, 0.01, 0.02, 0.03, and 0.05), prepared by the standard ceramic method, has been studied. It is found that the saturation magnetization increases up to x = 0.01 and then it decreases. On the other hand, the initial permeability decreased while the Curie temperature remained a...
متن کاملCavitation instability in bulk metallic glasses
Recent experiments have shown that fracture surfaces of bulk metallic glasses (BMGs) usually exhibit an intriguing nanoscale corrugation like fractographic feature mediated by nanoscale void formation. We attribute the onset of this nanoscale corrugation to TTZs (tension transformation zones) mediated cavitation. In our recent study, the spall experiments of Zr-based BMG using a single-stage li...
متن کاملInterface Instability of Fe-Stabilized Li7La3Zr2O12 versus Li Metal
The interface stability versus Li represents a major challenge in the development of next-generation all-solid-state batteries (ASSB), which take advantage of the inherently safe ceramic electrolytes. Cubic Li7La3Zr2O12 garnets represent the most promising electrolytes for this technology. The high interfacial impedance versus Li is, however, still a bottleneck toward future devices. Herein, we...
