Abstract

Concerning the safety aspects of Li⁺ ion batteries, an epoxy-reinforced thin ceramic film (ERTCF) is prepared by firing and sintering a slurry-casted composite powder film. The ERTCF is composed of Li⁺ ion conduction channels and is made of high amounts of sintered ceramic Li₁₊_xTi_2-_xAl_x(PO₄)₃ (LATP) and epoxy polymer with enhanced mechanical properties for solid-state batteries. The 2D and 3D characterizations are conducted not only for showing continuous Li⁺ ion channels thorough LATP ceramic channels with over 10⁻⁴ S cm⁻¹ of ionic conductivity but also to investigate small amounts of epoxy polymer with enhanced mechanical properties. Solid-state Li⁺ ion cells are fabricated using the ERTCF and they show initial charge–discharge capacities of 139/133 mAh g⁻¹. Furthermore, the scope of the ERTCF is expanded to high-voltage (>8 V) solid-state Li⁺ ion batteries through a bipolar stacked cell design. Hence, it is expected that the present investigation will significantly contribute in the preparation of the next generation reinforced thin ceramic film electrolytes for high-voltage solid-state batteries.
