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.

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.

Abstract: A reconfigurable electromagnetic wave shielding filter is provided in a wireless charger for a vehicle and capable of selectively shielding an electromagnetic wave (EMI noise) that interferes with an AM broadcast band, an electromagnetic wave that interferes with a FM broadcast band, and an electromagnetic wave that interferes with a DMB broadcast band. A wireless charger for a vehicle includes the reconfigurable electromagnetic wave shielding filter and a control method thereof, in which broadcast information being received by the user is collected, and then, an electromagnetic wave that interferes with a broadcast band corresponding to the collected broadcast information is shielded, thereby to allow the user to listen to the broadcast without noise.

Abstract: A method of removing common mode noise in a vehicle includes: a radio frequency (RF) switch connecting a feeder cable ground to a common mode (CM) filter or a digital signal processor (DSP) according to a selection signal of an amplitude modulation (AM) broadcast or a frequency modulation (FM) broadcast selected by a user and the CM filter increasing impedance of the feeder cable ground to remove the common mode noise.

Abstract: Disclosed herein is a dual-resonance broadband antenna, and more particularly, to such a dual-resonance broadband antenna in which dual resonance is caused to occur using an antenna consisting of a strip line, a microstrip line or the like having a meander pattern so as to receive a signal for a wireless communication service at a relatively low frequency band, particularly, a signal with a terrestrial digital multimedia broadcasting (T-DMB) service frequency band of 174-216 MHz among a very high frequency (VHF) band. Particularly, the dual-resonance broadband antenna of the present invention is remarkably red used in its size (length) as compared to a general helical antenna, a monopole antenna, a dipole antenna or the like while using a wireless communication service at a relatively low frequency band, thereby achieving miniaturization thereof.
