Abstract: Disclosed are a cathode for an all-solid-state battery including a cathode thin film for an all-solid-state battery or a cathode composite membrane for an all-solid-state battery, and an all-solid-state battery including the same. The cathode for an all-solid-state battery contains a grain that has a plane having a low surface energy and has a grain boundary arranged parallel to the electron movement direction, thus effectively lowering the interfacial resistance of the thin film while suppressing the dissolution and diffusion of the transition metal, thereby improving the cycle stability of the all-solid-state battery including the same.

Abstract: Disclosed is a catalyst used for steam carbon dioxide reforming of natural gas, wherein an alkaline earth metal alone or an alkaline earth metal and a group 8B metal are supported on a hydrotalcite-like catalyst containing nickel, magnesium and aluminum. The disclosed catalyst is useful as a steam carbon dioxide reforming (SCR) catalyst of natural gas at high temperature and high pressure, while minimizing deactivation of the catalyst due to sintering of the active component nickel and deactivation of the catalyst due to coke generation at the same time. A synthesis gas prepared using the catalyst has a H2/CO molar ratio maintained at 1-2.2. A synthesis gas having a H2/CO molar ratio of 1.8-2.2 may be used as a raw material for Fischer-Tropsch synthesis or methanol synthesis and a synthesis gas having a H2/CO molar ratio of may be used as a raw material for dimethyl ether synthesis.
