Amorphous modified silyl-terminated 3D polymer electrolyte for high-performance lithium metal battery

Amorphous polymer electrolyte using a novel modified silyl-terminated polyether possess high ionic conductivity (~ 0.36 mS cm−1) at room temperature, much higher thermal stability (Tm = 379 °C), high lithium ion transference number (~ 0.65), stable electrochemical window up to 5.0 V (vs. Li+/Li) and an excellent compatibility to the electrode. The lithium metal battery with developed polymer electrolyte present excellent electrochemical performance, showing strong potential for practical applications.309
