Synergized Tricomponent All-Inorganics Solid Electrolyte for Highly Stable Solid-State Li-Ion Batteries.

ABSTRACT: Garnet-type oxide Li_6.4 La₃ Zr_1.4 Ta_0.6 O₁₂ (LLZTO) features superior ionic conductivity and good stability toward lithium (Li) metal, but requires high-temperature sintering (≈1200 °C) that induces high fabrication cost, poor mechanical processability, and high interface resistance. Here, a novel high-performance tricomponent composite solid electrolyte (CSE) comprising LLZTO-4LiBH₄ /xLi₃ BN₂ H₈ is reported, which is prepared by ball milling the LLZTO-4LiBH₄  mixture followed by hand milling with Li₃ BN₂ H₈ . Green pellets fabricated by heating the cold-pressed CSE powders at 120 °C offer ultrafast room-temperature ionic conductivity (≈1.73 × 10
