  • 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: 10887517
    Abstract: The present invention relates to an image stabilization control device for an imaging device, the image stabilization control device stabilizing the shaking of a subject, caused by vibration applied to an imaging device, and comprising: filters for outputting rotational angular speed data in which a low-frequency component is removed from a rotational angular speed outputted from each of vibration detection sensors of an imaging device according to filter coefficients, which are variably set; a lens moving distance calculation unit processing output signals of the filters so as to calculate a lens moving distance; and a filter coefficient variable control unit for varying the filter coefficients of the filters in order to increase a lens return speed in a lens movement limited area, when the lens moving distance outputted from the lens moving distance calculation unit goes beyond the lens movement limit area having been virtually set.
