Thermodynamics as a Driving Factor of LiCoO Grain Growth on Nanocrystalline Ta-LLZO Thin Films for All-Solid-State Batteries.

All-solid-state batteries primarily focus on macrocrystalline solid electrolyte/cathode interfaces, and little is explored on the growth and stability of nanograined Li-garnet and cathode ones. In this work, a thin (∼500 nm) film of LiCoO (LCO) has been grown on top of the polycrystalline layer of Ta-doped LiLaZrO (Ta-LLZO) solid electrolyte using the pulsed laser deposition (PLD) technique. Scanning transmission electron microscopy, electron diffraction, and electron tomography demonstrated that the LCO film is formed by columnar elements with the shape of inverted cones.

Li-based layered nickel-tin oxide obtained through electrochemically-driven cation exchange.

The Li-based layered nickel-tin oxide LiNaNiSnO has been synthesized electrochemically-driven Li for Na exchange in O3-NaNiSnO. The crystal structure of LiNaNiSnO was Rietveld-refined from powder X-ray diffraction data ( = 3.03431(7) Å, = 14.

Chemistry, Local Molybdenum Clustering, and Electrochemistry in the LiMoO Solid Solutions.

A broad range of cationic nonstoichiometry has been demonstrated for the Li-rich layered rock-salt-type oxide LiMoO, which has generally been considered as a phase with a well-defined chemical composition. LiMoO (-0.037 ≤ ≤ 0.
