  • Publication number: 20250132396
    Abstract: An all-solid-state secondary battery includes a cell stack having a stack structure, and a protective member including a first thermoplastic resin layer, a second thermoplastic resin layer, and a third thermoplastic resin layer sequentially stacked, and being disposed on a peripheral portion, in which the cathode layer is not disposed, of the solid-state electrolyte layers, while being interposed between the two solid-state electrolyte layers disposed to be adjacent to each other such that the cathode layer is interposed between the two solid-state electrolyte layers. A glass transition temperature of the first thermoplastic resin layer and a glass transition temperature of the third thermoplastic resin layer are lower than a glass transition temperature of the second thermoplastic resin layer.

  • Patent number: 10308221
    Abstract: A method for preventing a relay attack of a smart key system for a vehicle according to the present invention accurately calculates a current spaced distance between an SMK unit and a fob key by using an RSSI included in a response signal and a current voltage level in a process of decoding the response signal when the fob key carried by a user receives a signal applied from the SMK unit installed in a vehicle and then transmits the response signal having at least two kinds of information to the SMK unit, and detects a challenge signal applied from the SMK unit installed in the vehicle and a noise signal included in the response signal, thereby enabling an operation of the vehicle only in a state where the carrier of the fob key secures a predetermined visual distance from the vehicle, and more definitely preventing a third party from breaking into the vehicle through RF bi-directional authentication.
