We report a novel chemical aliovalent substitution strategy that induces lithium vacancy generation, expands 3D Li migration channels, and reduces activation energy. The optimized composition LiZrNbCl achieves a room-temperature ionic conductivity twice higher than that of pristine LiZrCl, realizing stable cycling in all-solid-state lithium-ion batteries.

Lithium-ion conductors are one of the key features of all-solid-state lithium-ion batteries. To modify their properties and enable their implementation in high-performance devices, an understanding of the relationship between the crystal structure and the transport properties of the mobile species is important. Lithium phosphidotetrelates and -trielates are classes of lithium-ion conductors reaching ionic conductivities of up to 4.

Halide electrolytes have gained interest due to their decent conductivities in the mS·cm range and wide electrochemical stability windows. The ionic transport can be influenced by changing the Li concentration in the structure. Due to the high cost of the rare-earth elements in the halide electrolytes, the substitution of lower-cost elements is favored.

Solid-state electrolytes enable next-generation batteries that can theoretically deliver higher energy densities while improving device safety. However, when fabricating cathodes for all-solid-state batteries, solid-state electrolytes must be combined with the active materials in high weight fractions in order to achieve sufficient ionic percolation within the cathode composite. This requirement drastically hinders the practicality of solid-state batteries as the solid-state electrolyte is conventionally designed to be electrochemically inactive and is effectively electrochemical "dead weight", lowering both the gravimetric and volumetric energy density of the cell.

Mid-infrared (MIR) nonlinear optical (NLO) materials play a crucial role in laser technology applications, yet their rational structural design remains a significant challenge. In this article, guided by the aliovalent substitution strategy, two novel MIR NLO crystals, RbCdVOBr and RbCdVOBr, were designed and successfully synthesized. RbCdVOBr crystallizes in noncentrosymmetric tetragonal space group 4, featuring the two-dimensional (2D) [CdVOBr] layer structure.
