| Summary: | This study aims to develop a single-cell prototype of a bulk all-solid-state electrolyte lithium-ion battery (ASSELIB) using the multi-layer co-fired ceramic (MLCC) method. The primary active materials selected for these experiments were as follows: i) solid-state electrolyte material: lithium aluminium titanium phosphate (Li1.3Al0.3Ti1.7(PO4)3, LATP) with a NaSICON structure, ii) cathode material: lithium nickel cobalt manganese oxide (LiNi0.8Co0.1Mn0.1O2, NCM) and iii) anode material: a mixture of lithium titanium oxide (Li4Ti5O12, LTO) with a spinel structure and titanium dioxide with a rutile structure (R-TiO2). The powders of these three components were sequentially layered into a specific mould, forming three distinct layers: cathode, electrolyte and anode. The electrolyte layer was placed between the cathode and anode layers to ensure effective separation and prevent direct contact. The layered sample was then subjected to high pressure, creating a solid laminated bulk structure. At high temperatures, the solid components were co-sintered to form a well-connected interface that allows lithium ions to migrate smoothly across the electrolyte, moving between the cathode and anode. In this study, influences of different composition of ASSELIB layers and different co-fired temperatures (600, 650, 700, 750 and 800°C) on the performances of the ASSELIB single cell were investigated. The battery’s physical properties, density changes and electrochemical characteristics were evaluated, including the formation quality of solid interfaces between each layer, ensuring no chemical interaction between components. Future work will be focused on optimizing the cell by adjusting experimental parameters for enhanced performance. |
