This technology relates to liquid-solidcomposite electrolytes and concerns that they can be applied to all solid-statebatteries for improved safety and performance. In particular, it is atechnology designed to enhance performance, durability, stability, andapplicability based on key materials, structures, processes, or deviceconfigurations related to liquid-solid composite electrolytes, theirmanufacturing methods, and their applications.
By providing liquid-solid compositeelectrolytes, the aim is to resolve safety issues associated with traditionallithium-ion batteries and improve the performance of all solid-state batteries.Accordingly, this technology proposes a technical concept that utilizes aliquid electrolyte coated on the surface and interior of sulfide solidelectrolyte pellets as a core means, and implements a stable passivation layerformed at the interface between the working electrode and the solidelectrolyte.
Accordingly, the present invention isexpected to improve the stability and performance of all solid-state batteriesby reducing internal pore formation and enhancing the physical and chemicalstability of the electrolyte-electrode interface, while simultaneouslyincreasing reproducibility, scalability, and process suitability in actualoperating environments. Furthermore, it can be utilized as a high-performancematerial, device, battery, sensor, apparatus, or manufacturing process inrelated industries, making it advantageous in terms of subsequentcommercialization and demonstration development.
