Hybrid electrolytes with an ultrahigh Li-ion transference number for lithium-metal batteries with fast and stable charge/discharge capability

An ultra-high Li + transference number of 0.92 and an ionic conductivity of 0.85 mS cm −1 at room temperature are achieved by using anion-anchoring α-LiAlO 2 @γ-Al 2 O 3 nanosheets as fillers in PVDF-based electrolytes.
