  • Patent number: 10297830
    Abstract: The present invention relates to a polymer-sulfur copolymer, a preparation method thereof, and a lithium-sulfur battery including the same. In the case of the polymer-sulfur copolymer according to the present invention, since the carrier is polymerized, there is no possibility that the carrier is eluted, and since the sulfur is covalently bonded to the polymer and uniformly distributed in a certain size in the copolymer, when used as a positive electrode active material for the lithium-sulfur battery, the problem of elution of the polysulfide can be improved. In addition, the polymer-sulfur copolymer according to the present invention has a high sulfur impregnation amount, thereby making it possible to realize a high capacity battery.

  • Patent number: 10254391
    Abstract: Provided is a radar detector for detecting and recognizing, as a control signal, a hand gesture or a motion of a user and transferring the same to a peripheral device. The radar detector utilizes position information of GPS or GLONASS by additionally mounting a GPS receiving unit to the radar detector so as to amend malfunctions of the radar detector in environments in which interference from undesired signals may be received, such as areas of heavy jamming, downtown areas where various signals are generated, etc., and to enable a user to arbitrarily add (or delete) a notification refusal area or a notification area. The radar detector is expected to contribute to safe driving by increasing control convenience of a driver and preventing traffic accidents.
