As the number of lithium-ion batteries discarded at the end of their lifespan increases, interest in ways to recycle them is increasing. In this paper, an experiment was conducted to recover cathode active materials from spent lithium-ion batteries using solvents as part of direct recycling, and the electrochemical properties of the cathode active materials recovered for each solvent were reported. The experimental results suggest the possibility of recycling the recovered cathode active materials.

All-solid-state batteries are attracting attention as next-generation secondary batteries for electric vehicles or ESS because they do not pose the risk of explosion or fire. However, most solid electrolytes have limitations in practical use due to the difficulty in expanding them to large areas. In this study, a composite solid electrolyte sheet combining an oxide-based inorganic solid electrolyte and a polymer solid electrolyte was manufactured through a tape casting process. As a result, it was confirmed that the manufactured composite solid electrolyte sheet had an ionic conductivity in the range of 3.33 to 4.45 × 10<SUP>-4</SUP> S/cm and a uniform thickness in the range of 39 to 41㎛. In addition, as a result of manufacturing Li/CSE/LFP cells and evaluating their cycle characteristics, they showed a high capacity retention rate of 82.33% in 50 cycles at 0.33 C and 70℃. Therefore, this study provides a practical strategy for fabricating all-solid-state batteries based on composite solid electrolytes.
