LZCO (Li1.75ZrCl4.75O0.5) Powder as Solid-State Electrolyte for Lithium-Ion Battery, 10-50 g/bottle, CLIBSSELZCO

The Li-Zr-Cl-O (Lithium Zirconium Oxychloride or LZCO) system represents a major evolutionary step in the field of Halide Solid-State Electrolytes (HSSEs). While pristine zirconium halides like Li2ZrCl6 (LZC) gained attention due to the extreme earth abundance and low cost of zirconium (~ 6 $/kg), their practical application was severely bottlenecked by low room-temperature ionic conductivity (~10^{-5} S/cm to 10^{-4} S/cm). By partially substituting chlorine (Cl-) with oxygen (O}^{2-}), researchers unlocked a class of mixed-anion oxychloride superionic conductors that dramatically improve lithium-ion kinetics.

The inclusion of oxygen into the halide lattice completely alters the crystal structure and energy landscape for Li+ transport: (1) Phase Transition & Disorder: Introducing the smaller, higher-valence oxide ion (O^{2-}) for Cl- induces severe lattice distortions or drives a phase transition (such as transitioning into a monoclinic structure like Li6ZrCl6O2). This structural perturbation opens up the coordination bottlenecks. (2) Amorphization: At higher oxygen doping thresholds or when synthesized via high-energy ball milling, the coupled cation-anion mismatch breaks down long-range crystalline symmetry entirely. The resulting amorphous oxychloride network offers isotropic ion conduction paths, eliminating grain-boundary resistances. (3) Vacancy Generation: Because O^{2-} has a higher negative charge than Cl-, its incorporation allows for the structural manipulation of Li+ concentration and vacancies, lowering the migration activation energy (0.25 eV) and accelerating long-range cooperative ion hopping.
