Li⁺ selective transport network-assisted high-performance of garnet-based solid electrolyte for Li metal batteries

Abstract

The interface contact of Li/LLZO is addressed by the in situ construction of a 3D cross-linked Li+ selective transport network for Li+ transfer (BiLi3) and electron blockage (LiCl) using thermal lithiation with BiCl3.

Two-step cold sintering of Li1.3Al0.3Ti1.7(PO4)3 composite solid electrolyte with non-equilibrium microstructures for enhanced electrochemical performance

“…The rough surface of the solid electrolyte generates multiple gaps between the solid electrolyte and the LMA, leading to an elevated polarization voltage of the symmetrical battery. 41 The direct contact between LATP and the LMA further intensifies side reactions, resulting in voltage fluctuations during cycling. With the accumulation of side reactions, the polarization voltage steadily increases from 630 h onwards.…”

Computational approach inspired advancements of solid-state electrolytes for lithium secondary batteries: from first-principles to machine learning

“…Recently, the adoption of electronic blocking layers like LiH, LiF, Li 3 N and organic lithium salts on the surfaces of SIE particles has been observed to increase the critical electrical bias for dendrite growth, enhance ionic conductivity and oxidation stability, and has gained popularity as a promising direction for modifying electrode–SSE pairs. 234–236 Surface coating techniques, such as liquid-phase deposition of nanosized SIEs, 237 lithiophilic metallic 238 or electron-blocking interlayers, 239 electrodeposition, 240 and removal of impurities, 241 have also been explored to address various issues encountered by lithium metal batteries and facilitate intimate contact with SSEs, forming nanoscale electronic/ionic transportation networks for high reversibility capacity and superior rate capability. However, achieving the desired rate performances for fast-charging targets of electric vehicles still poses challenges.…”
