Abstract: The present disclosure relates to a cathode active material for an all-solid-state battery with a controlled particle size and a method for preparing the same. In particular, the cathode active material includes lithium and a transition metal, wherein the cathode active material has a single peak in the range of 1 ?m to 10 ?m as a result of particle size distribution (PSD) analysis.

Abstract: The present invention is directed to a novel complex synthesized from a Salen-type ligand. The novel complex contains a quaternary ammonium salt. The present invention is also directed to a preparation method of a copolymer of carbon dioxide and epoxide using the complex synthesized from a Salen-type ligand as a catalyst.

Abstract: Provided are a complex synthesized from a novel tridentate ligand including an ammonium salt and a process of producing polycarbonate by copolymerization of carbon dioxide and epoxide using the same as a catalyst. A novel tridentate complex may be cheaply prepared as compared to the existing tetradentate complex containing four ammonium salts but have an advantage in that the novel tridentate complex may have an activity at a level similar to that of the existing tetradentate complex by adopting a cis-? conformation. Further, since in the tridentate complex, the number of ammonium salt serving as an initiator is small but the number of vacant sites is large as compared to the tetradentate complex containing four ammonium salts, the tridentate complex may have excellent activity.

Abstract: A novel polymeric compound is provided. The polymeric compound is highly compatible with reinforcing materials. Particularly, the polymeric compound is highly miscible with inorganic reinforcing materials in the manufacture of a tire. Further provided is a novel bifunctional initiator necessary to prepare the polymeric compound. The bifunctional initiator contains amine moieties. Active ends of the polymer are modified with an alkoxysilane compound. The polymer has an improved affinity for carbon black and silica as reinforcing materials in the manufacture of a tire. Therefore, the use of the polymer can achieve desired physical properties required in a tire, e.g., high wet traction, low rolling resistance and high tread wear.
