The present invention relates to a structure for attachment/detachment of an energy pack for an electric vehicle and, more specifically, a structure for attachment/detachment of an energy pack for an electric vehicle, wherein: the energy capacity of a main energy supply device is reduced, and thereby fuel economy/efficiency can be increased through weight reduction; and an energy pack capable of additional energy supply is separately provided and detachably attached inside the vehicle depending on the travel distance of the vehicle, and thereby the driving conditions of the electric vehicle can be optimized without a need to change driving qualifications.

Structure for attachment/detachment of energy pack for electric vehicle

A display apparatus is provided including a first substrate on which a plurality of organic light-emitting diodes are arranged. A second substrate is bonded to the first substrate. The second substrate includes a plurality of light control units respectively corresponding to the plurality of organic light-emitting diodes and a plurality of banks arranged between the plurality of light control units. The plurality of banks include a first bank having a deflection arrangement structure in which a fluorine-containing polymer is concentrated on a surface of a side of the first bank, and a second bank that does not have a deflection arrangement structure in which the fluorine-containing polymer is deflectively arranged.

Display apparatus including a plurality of banks and a method of manufacturing the same

An electrode for a rechargeable lithium battery includes a current collector, an electrode active material layer on at least one surface of the current collector, a carbon-based coating layer between the current collector and the electrode active material layer, the carbon-based coating layer being formed from a carbon-based slurry including a carbon-based material, a first binder, and a thickener. A content of the first binder is about 35 wt % to about 70 wt % based on the carbon-based coating layer.
