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: The present invention discloses a wireless transmitting/receiving apparatus for transmitting and receiving large amounts of digital data using a commercial wireless transmitting/receiving apparatus. The wireless transmitting apparatus includes a data converter for mapping multibit digital data by a data symbol in accordance with a predetermined mapping table, for converting the data symbol to an analog signal, and for outputting the analog signal, and a wireless transmitter for modulating the analog signal and for transmitting the signal wirelessly. The wireless receiving apparatus includes a wireless receiver for demodulating a wireless signal received to an analog signal, and a data restoration section for converting the analog signal to a digital signal in accordance with a predetermined mapping table, conducting an inverse symbol mapping on the digital signal, and outputting the digital signal.
