  • Publication number: 20240306270
    Abstract: A method includes: sensing a first container on an electric range by using at least one loop coil; sensing removal of the first container by using at least one of working coils; sensing a second container on the electric range by using at least one of loop coils; and determining an identity of the first container and the second container. The determining the identity is on the basis of at least one of: a first similarity determined based on damping vibration in each of at least one loop coil having sensed the first container and damping vibration in each of at least one loop coil having sensed the second container; and a second similarity determined based on the number of loop coils having sensed the first container and the number of loop coils having sensed the second container.

  • Patent number: 12044643
    Abstract: A sensor tube according to the present disclosure includes a body including a body extension having opposite ends connected to measurement air connection pipes and an opening, the measurement air connecting pipes being connected to a humidity sensor to deliver moisture to the humidity sensor using measurement air or allow the measurement air released from the humidity sensor to flow therethrough, and the opening being formed in the body extension to cause an interior space of the body extension and the outside to be in communication with each other such that the moisture is introduced into the interior space of the body extension from the outside through the opening, and an opening/closing part that selectively opens or closes the opening by being operated by a difference in pressure between the interior space of the body extension and the outside.

  • Publication number: 20240243273
    Abstract: A positive electrode active material and method of preparing the same are disclosed herein. The positive electrode active material can have high capacity and high rate capability. In some embodiments, a positive electrode active material includes lithium transition metal oxide particles having a lithium transition metal oxide represented by Formula 1, wherein an interplanar spacing of (003) crystal planes ((003) d-spacing) of the lithium transition metal oxide of a surface of the particles is larger than a (003) d-spacing of the lithium transition metal oxide inside the particles: wherein 0.8?a?1.2, 0.6?x<1, 0<y<0.4, 0<z<0.4, and 0?w?0.1, and M1 is at least one selected from the group consisting of Al, Zr, B, W, Mg, Ce, Hf, Ta, La, Ti, Sr, Ba, F, P, and S.

  • Publication number: 20230125899
    Abstract: Electrode and electrode assembly manufacturing apparatuses include an electrode transfer unit for transferring an electrode with electrode coating layer on surface of the electrode, a cutter for cutting the electrode transferred by the electrode transfer unit to form a unit electrode, a separator transfer unit disposed at one surface of the electrode transfer unit and configured to transfer a separator, a sensor unit for sensing the position of the unit electrode and an alignment unit for adjusting transfer speeds of outer peripheries of the unit electrode parallel to a unit electrode transfer direction to adjust the interval between unit electrodes seated on a separator surface . Whether positive and negative electrodes are aligned before stacking and laminating electrodes having different polarities is determined. The positive and negative electrodes are then stacked, whereby the occurrence of a defective electrode due to misalignment between the positive and negative electrodes is preventable.

  • Publication number: 20230126211
    Abstract: A separator sheet adhesion apparatus is configured to form an electrode stack including first and second separator sheets, first electrodes disposed on and spaced apart along the first separator sheet by a first predetermined distance to define first separator spacing portions, second electrodes disposed on and spaced apart along the second separator sheet by a second predetermined distance to define second separator spacing portions. The apparatus includes an adhesion unit configured to press together and thereby adhere the first separator spacing portions and the second separator spacing portions at predetermined intervals corresponding to the first and the second predetermined distances, a support aligned with the adhesion unit and configured to support the electrode stack when the first and the second spacing portions are being pressed together. The adhesion unit includes an optional elastic material that contacts the first spacing portions during the pressing of the spacing portions.
