Abstract

A rapid rise in the development of portable electronic devices and telecommunication technologies has led to an ever-growing demand for high safety, large energy density, and cost-effective systems for storing energy. Rechargeable all-solid-state lithium-ion batteries are extremely productive without compromising performance. In this study, garnet-type Li<subscript>7</subscript>La<subscript>3</subscript>Zr<subscript>2</subscript>O<subscript>12</subscript> (LLZO) filler was prepared employing the sol–gel method. That follows, the high-performance poly(ethylene oxide)/lithium perborate (LiBO<subscript>3</subscript>)/LLZO composite solid polymer electrolyte was fabricated using a simple solution-casting technique. The morphology and composition of the prepared CSPE (composite solid polymer electrolyte) (PEO-LiBO<subscript>3</subscript>-LLZO) were investigated using X-ray diffraction and scanning electron microscopy in addition to other physicochemical characterization techniques. The composite solid polymer electrolyte exhibits a maximum ionic conductivity of 2.8 × 10<superscript>−4</superscript> S cm<superscript>−1</superscript> with LLZO filler and a wide electrochemical window of 4.5 V vs. Li<superscript>+</superscript>/Li. The prepared electrolyte reveals good electrochemical efficiencies with elevated discharge capacity of 73.4 mAhg<superscript>−1</superscript> and excellent coulombic efficiency of 99% since 100 cycles. Based on these results, the prepared composite solid polymer electrolyte furnishes an auspicious methodology for the advancement of high-performing rechargeable all-solid-state lithium-ion batteries.
