  • Publication number: 20240136674
    Abstract: Disclosed is an electrode assembly, a battery, and a battery pack and a vehicle including the same. In the electrode assembly, a first electrode, a second electrode, and a separator interposed therebetween are wound based on a winding axis to define a core and an outer circumference. The first electrode includes a first active material portion coated with an active material layer and a first uncoated portion not coated with an active material layer along a winding direction. At least a part of the first uncoated portion is defined as an electrode tab by itself. The first uncoated portion includes a first portion adjacent to the core of the electrode assembly, a second portion adjacent to the outer circumference of the electrode assembly, and a third portion interposed between the first portion and the second portion. The first portion or the second portion has a smaller height than the third portion in the winding axis direction.

  • Publication number: 20240128517
    Abstract: Disclosed is an electrode assembly, a battery, and a battery pack and a vehicle including the same. In the electrode assembly, a first electrode, a second electrode, and a separator interposed therebetween are wound based on an axis to define a core and an outer circumference. The first electrode includes an uncoated portion at a long side end thereof and exposed out of the separator along a winding axis direction of the electrode assembly. A part of the uncoated portion is bent in a radial direction of the electrode assembly to form a bending surface region that includes overlapping layers of the uncoated portion, and in a partial region of the bending surface region, the number of stacked layers of the uncoated portion is 10 or more in the winding axis direction of the electrode assembly.

  • Patent number: 10645168
    Abstract: An electronic device is provided. The electronic device includes a memory, a transceiver that communicates with at least one external device, and at least one processor that is electrically connected with the memory and the communication module. The at least one processor is configured to receive an utterance place candidate group and a command for controlling a peripheral device associated with an utterance place from at least one or more other electronic devices by using the transceiver and to store the received utterance place candidate group and the received command in the memory, to select at least one utterance place based on the received utterance place candidate group, and to transmit, to a peripheral device associated with the selected utterance place, a command for controlling the peripheral device.

  • Patent number: 10440170
    Abstract: An apparatus and method for transmitting/receiving a message in a mobile communication terminal with a touch screen are provided. The method includes generating a Simple Contact Object (SCO) mapped to at least one contact and a Simple Inputbox Object (SIO) for message composition, displaying the generated SCO and SIO on an idle screen in a widget format, composing a message using the displayed SIO, and storing the composed message in the SIO, and, when a contact between the SIO storing the message therein and the SCO is detected, transmitting the stored message to the contact mapped to the SCO.

  • Publication number: 20110021242
    Abstract: An apparatus and method for a Conversational Message (CM) function of a mobile communication system are provided. The apparatus includes a CM manager for defining information indicating a start and end of a CM function and information regarding a folder for storing message data exchanged with a peer portable terminal in a message to be transmitted, and for transmitting the defined message to the peer terminal. Accordingly, the CM function is improved by transmitting information for announcing that a CM is transmitted in a message transmission process to enable rapid response processing and by granting an access right on stored data when performing the CM function.
