Solid polymer electrolytes (SPEs) for lithium-ion batteries have attracted intensive attention due to their enhanced safety at high temperature. However, SPEs are generally suffering from relatively low ionic conductivity ranging from10-6–10-7 S cm-1, and more importantly, poor interfacial contact of electrode/electrolyte interfaces related to long-term cycle performance. In this research, a series of solid composite electrolytes were successfully prepared by chemically grafting the monomer with bulky non-polar unit, monodisperse ceramic nanocrystals and organic/inorganic hybrid particles to polyethylene oxide (PEO) matrix to improve the ionic conductivity and battery cycle performance. Compared to traditional PEO-based solid polymer electrolytes, this composite electrolyte not only exhibits high thermal stability and good ionic conductivity, but also yields excellent interfacial contact with lithium electrode and outstanding cycle performance in LIBs. It is anticipated that this work provides a new insight for designing advanced electrolytes for LIBs with enhanced safety and cycle performance at high temperature.
