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 are an electrolyte membrane of a membrane-electrode assembly including an electronic insulation layer, which greatly improves the durability of the electrolyte membrane, and a method of preparing the same. The electrolyte membrane includes an ion exchange layer and an electronic insulation layer provided on the ion exchange layer, and the electronic insulation layer includes one or more catalyst complexes, and a second ionomer Particularly, each of the one or more catalyst complex includes a catalyst particle and a first ionomer coated on the entirety or a portion of the surface of the catalyst particle, and the one or more catalyst complexes are dispersed the second ionomer.

Abstract: An apparatus to provide augmented reality includes an image acquisition unit to acquire an image including a target object, a supplementary information acquisition unit to acquire supplementary information, an object recognition unit to recognize the target object from the acquired image, and a candidate nomination unit to generate candidate objects based on the supplementary information. A method for providing augmented reality includes transmitting, at a terminal, an image including a target object or supplementary information of the target object, and location information of the terminal to a server; and determining, at the server, whether the target object is recognized, and generating a list of candidate objects based on the supplementary information, if the target object is not recognized.

Abstract: A terminal device stores augmented reality generated by merging an image of an object and attribute information associated with the object. The terminal device, and a method therefor, allow for retrieval of stored augmented reality information about selected objects if the terminal is no longer at a location where the object's image was captured. The terminal device obtains a preference level for the attribute information and displays the attribute information based on the preference levels. Based on usage of the attribute information, the terminal redetermines preference levels for the attribute information. If previously stored augmented reality is requested, the terminal displays the previously stored augmented reality based on the redetermined preference levels.
