Electrochemical Stability of Li₁₀GeP₂S₁₂ and Li₇La₃Zr₂O₁₂ Solid Electrolytes

DOI: 10.1002/aenm.201501590 electrochemical stability window, and (3) chemical compatibility with the anode and cathode. In the past few years, major advances have been achieved in increasing the Li ionic conductivity of the solid electrolytes. The state-of-the-art solid electrolyte materials, such as Li-garnet Li 7 La 3 Zr 2 O 12 (LLZO) and Li 10 GeP 2 S 12 (LGPS) have achieved an ionic conduc...

Effect of Rb and Ta Doping on the Ionic Conductivity and Stability of the Garnet Li_{7+2<italic>x</italic><italic>y</italic>}(La_{3<italic>x</italic>}Rb_{<italic>x</italic>})(Zr_{2<italic>y</italic>}Ta_{<italic>y</italic>})O₁₂ (0 <italic>x</italic> 0.375, 0 <italic>y</italic> 1) Superionic Conductor: A First Principles Investigation

In this work, we investigated the effect of Rb and Ta doping on the ionic conductivity and stability of the garnet Li7+2x−y(La3−xRbx)(Zr2−yTay)O12 (0 ≤ x ≤ 0.375, 0 ≤ y ≤ 1) superionic conductor using first principles calculations. Our results indicate that doping does not greatly alter the topology of the migration pathway, but instead acts primarily to change the lithium concentration. The st...

A Novel Phase of Li₁₅Si₄ Synthesized under Pressure

However, in situ X-ray diffraction (XRD) studies on the lithiation /delithiation of Si anodes confi rmed the absence of the above-mentioned stable compounds in the electrochemical reaction in Li-ion batteries at room temperature. [ 12,13 ] The only crystalline lithium silicide formed is Li 15 Si 4 (space group 43 I d), a metastable phase that decomposes to Li 13 Si 4 , Li 17 Si 4 /Li 4.11 Si, o...
