Summary

Led comprehensive research on advanced solid electrolytes for solid-state metal batteries, focusing on synthesis, interface engineering, and electrochemical performance.

Highlights

Developed a scalable synthesis route for neck-fused cubic LLZO (Li7La3Zr2O12), integrating solvated ionic liquid (SIL) and interfacial liquid therapy to enable facile Li+ transport.

Engineered novel "plate-like" and "interconnected" LLZO architectures using bio-templating (water hyacinth, cellulose) to significantly minimize grain-boundary resistance and enhance ion conduction.

Introduced an innovative solid-liquid dual therapy utilizing NiO sintering aid and SIL to fabricate highly conductive, dense, and mechanically robust hybrid electrolytes.

Established dual interfacial engineering through NH4F fluorination and SIL infusion, achieving stable Li/LLZO interfaces with a critical current density (CCD) greater than 1 mA cm².

Developed Al/S-modified LLZO, enhancing bulk conductivity and extending liquid therapy strategies to NZSP for high-performance sodium metal batteries.

Fabricated flexible LLZO impregnated composite membranes (polymer and paper-polymer systems), demonstrating high ionic conductivity and long-term Li cycling stability exceeding 500 cycles.
