Supramolecular polymer electrolyte with fast molecular shuttles for solid-state lithium batteries |
초록 |
The fast molecular shuttle inside a supramolecular polymer can enhance the ionic conductivity and charge transport capability of the solid polymer electrolyte and maintain mechanically tough properties. The supramolecular polymer electrolyte with fast molecular shuttles exhibits high ionic conductivity (σ>1 mS cm−1), Li+-ion transference number (t+=0.71), and electrochemical oxidation stability (≈4.7 V versus Li+/Li) at room temperature. Applications of the polymer electrolyte in LiFePO4-Li, LiNi0.8Mn0.1Co0.1O2-Li, and LiNi0.8Mn0.1Co0.1O2-graphite batteries further demonstrate that high Coulombic efficiency (≥98.5%) with excellent rate-capability and quick charge performance (≥2C) can be achieved with a fast molecular shuttle design. |
