Abstract

Lithium-metal batteries (LMBs) are promising energy storage devices due to the high capacity and minimum negative electrochemical potential. Their concrete applications remain disturbed by unbalanced electrolyte-electrode interfaces, limited electrochemical window, and high-risk. Herein, a novel strategy to prepare ceramic-based electrolyte that possess great potential in energy storage due to their higher level of energy densities in LMBs. lanthanum titanate (LTO) and Aluminum Titanium Phosphate (LTP) film developed via the UV system, aimed to prepare flexible Li+ interpenetrating network film to integrate the ceramic structure with polymer to yield the free-standing electrolyte film for better battery safety and desired interfacial stability. The electrolyte presented a satisfactory electrochemical performance, including, good ionic conductivity, large transference number, and wide electrochemical stability window (ESW) at room temperature. The fundamental function of nano fillers is to support building a stable (SEI) and limits the growth of dendrites. Thus, prepared ceramic-based electrolytes effectively renders to inhibit lithium dendrite growth in a symmetrical cell during charge/discharge at a current density of 2 mA/cm2 above standards without short-circuiting at room temperature. The battery assembled that exhibits superior cyclic stability with high columbic efficiency. This work recommends that the structures of Li-ion conductor help to design a prime solution of promising electrolyte for high-performance applications.
