Multifunctional BN-Enabled Li7La3Zr2O12 Composite Electrolytes with Enhanced Toughness and Ionic Conductivity
This study demonstrates that an ultrafast sintering strategy incorporating a minimal amount of hexagonal boron nitride (BN) significantly enhances both the toughness and ionic conductivity of Li7La3Zr2O12 (LLZO) composite electrolytes by promoting densification and reducing interfacial resistance through the formation of Li3BO3.
