Abstract: A battery cell including an electrode assembly and a case accommodating the electrode assembly is provided. The case includes a plurality of corner portions and a planar portion disposed between the plurality of corner portions, and the planar portion is configured to press the electrode assembly, when the electrode assembly swells.

Abstract: A battery cell and a battery device including the same are disclosed. In some implementations, the battery cell includes an electrode assembly including an electrode foil, an electrode terminal electrically connected to the electrode foil, and a positive temperature coefficient (PTC) fuse coupled to the electrode terminal, the PTC fuse including a PTC material. The PTC fuse blocks or limits current flow between the electrode terminal and the outside at a set temperature or higher.

Abstract: A battery cell is provided. The battery cell includes an electrode assembly; a housing including a case accommodating the electrode assembly and a cap assembly covering the case; and a thermochromic member thermally connected to the housing. The thermochromic member may include a thermochromic region configured to change color based on temperature.

Abstract: A battery cell is provided. The battery cell includes an electrode assembly including an active material and a foil, a case accommodating the electrode assembly, a cap assembly connected to the case and including a terminal, and a current collecting structure connecting the foil to the terminal.

Abstract: A battery cell includes an electrode assembly including an electrode foil; an electrode terminal electrically connected to the electrode foil; and a thermal fuse coupled to the electrode terminal and deformable at a set temperature or higher, wherein the thermal fuse is configured to block a current flow between the electrode terminal and outside of the plurality of battery cells at a set temperature or higher.

Abstract: A sterilization apparatus includes a housing; a sterilization unit for irradiating, with sterilization light, at least one region to be sterilized; and a driving unit for moving the sterilization unit into and out of the housing via an opening of the housing and rotating the sterilization unit about a rotation axis.

Abstract: The present invention relates to a method for preparing an alkali metal ion conductive chalcogenide-based solid electrolyte, a solid electrolyte prepared thereby, and an all-solid-state battery comprising the same.

Abstract: An apparatus and method for treating a substrate are provided. The apparatus includes at least one first process chamber configured to supply a developer onto the substrate; at least one second process chamber configured to treat the substrate using a supercritical fluid; a transfer chamber configured to transfer the substrate from the at least one first process chamber to the at least one second process chamber, while the developer supplied in the at least one first process chamber remains on the substrate; and a temperature and humidity control system configured to manage temperature and humidity of the transfer chamber by supplying a first gas of constant temperature and humidity into the transfer chamber.

Abstract: An emissive display device includes a display area which includes a plurality of pixels, and a driver disposed at a side of the display area, where the driver includes at least two emission signal stages disposed in one row, and an input signal line connected to the emission signal stages, and the at least two emission signal stages are connected to the same input signal line.

Abstract: The present application introduces a musical instrument stand which can be easily carried or installed, comprising: a first part in which a stopper piece extends upward on one side of a support body for placing musical instrument; a second part elastically connected to the first part and extendable in the longitudinal direction with respect to the first part; and a locking means provided on the first and second parts and a fixing force to a counterpart.

Abstract: Provided is a device and method for providing an Alternative Frequency (AF) in a wireless terminal, by which an AF channel service suitable for a user environment can be provided. To this end, the device includes a radio broadcast receiver for receiving a radio broadcast signal, and a controller for attempting an AF channel switch after an elapse of a re-try wait time which is set according to a number of recent AF channel switch failures. The controller may detect the user environment as a walking state or a driving state. If a driving state is detected, the AF channel switch is attempted immediately when receive signal quality is below a threshold, regardless of the number of recent AF channel failures. If a walking state is detected, the AF channel switch is attempted after the elapse of the wait time.

Abstract: A method of detecting a web application attack is provided. The method includes the steps of when packets forming HTTP traffic are received, a web application firewall recombining the HTTP traffic, analyzing the recombined HTTP traffic and determining whether or not the recombined HTTP traffic includes the attack-relevant content, if the recombined HTTP traffic does not include the attack-relevant content, sending the recombined HTTP traffic to a web server or a user server and normally processing the recombined HTTP traffic, and if the recombined HTTP traffic includes the attack-relevant content, detecting the recombined HTTP traffic as an attack and reprocessing the same.
