Abstract: An electrolyte for a lithium secondary battery including a wettability-improving additive having a trifluoromethylsulfonyl group. The electrolyte has reduced surface tension to improve the wettability of an electrode assembly with the electrolyte. Therefore, it is possible to ensure high electrolyte wettability even when the electrolyte includes a high-boiling point solvent or a high concentration of lithium salt.

Abstract: A non-aqueous electrolyte for a lithium secondary battery and a lithium secondary battery including the same are provided. The non-aqueous electrolyte includes a compound represented by the following formula, R1-O—CH2—R2, in an amount of 2 wt % to 50 wt % based on a total weight of the non-aqueous electrolyte, an organic solvent containing a nitrile-based solvent in an amount of 90 vol % to 100 vol %, and a lithium salt.

Abstract: An embodiment method of operating a cell-based mobility production system for producing various types of mobilities includes assigning works required in each cell of a plurality of cells connected in series or in parallel that vehicle bodies need to go through based on the type of the mobility to be produced, determining a feeding order of the vehicle bodies based on the assigned works, and reassigning the works required in each cell that the vehicle bodies to be fed need to go through based on the determined feeding order, wherein each of assigning the works, determining the feeding order, and reassigning the works is performed by a processor.

Abstract: The present invention relates to an apparatus for pressing a secondary battery. The apparatus for pressing a secondary battery comprises a disposing member on which the secondary battery comprising an electrode assembly and a pouch is disposed, and a pressing member configured to press the secondary battery disposed on the disposing member, wherein the pressing member comprises an accommodation part pressing jig configured to press an accommodation part of the pouch, in which the electrode assembly is accommodated, in the pouch of the secondary battery disposed on the disposing member, and a sealing part pressing jig configured to press a sealing part formed along an edge surface of the accommodation part in the pouch of the secondary battery disposed on the disposing member, wherein the sealing part pressing jig is coupled to a surface of the accommodation part pressing jig corresponding to the sealing part to press the sealing part through pressing force transmitted from the accommodation part pressing jig.

Abstract: A dry etching method includes a first step of adsorbing first radicals into a surface of an etching target, wherein the first radicals are contained in first plasma generated from a plasma generator; and a second step of irradiating ion-beams extracted from second plasma generated from the plasma generator onto the surface of the etching target into which the radicals have been adsorbed, thereby desorbing a surface atomic layer of the etching target, wherein the first step is performed such that: a positive potential greater than a potential of the first plasma is applied to one or two selected from first to third grids, while a ground potential is applied to the rest thereof; and a negative potential equal to or lower than a potential of the third grid is applied to a substrate support structure.

Abstract: Disclosed is a method for manufacturing a semiconductor light emitting device. The method includes a first step of forming a semiconductor structure in which a first conductive-type semiconductor layer, an active layer, and a second conductive-type semiconductor layer are sequentially stacked; and a second step of forming a mesa structure by removing a portion of each of the second conductive-type semiconductor layer and the active layer, wherein the second step includes: forming a mesa structure by etching a portion of each of the second conductive-type semiconductor layer and the active layer using a plasma etching process; and performing an atomic layer etching process on a surface of the mesa structure formed by the plasma etching process.

Abstract: The present invention relates to a character arrangement method and a character input method in an electronic device. A telephone-style keypad is assigned symbolic word representations to provide a heuristic and intuitive text input interface to a user. The symbolic word representations on at least some keys on the keypad can create multiple numbers of same alphabets, which can be utilized for easier text entry of frequently-used alphabets. Leftover alphabets which did not get inscribed by the symbolic word representations on some of the keys are grouped together and assigned to leftover keys.

Abstract: Disclosed herein, a new concept of numeral created from alphabet is able to apply in education, telecommunication, computer and toy industry. For the sake of applicability, the present invention provides substitution methods where alphabet is replaced to the corresponding arabic numeral by similarity in shape, similar pronunciation with numbers, similarity in Roman and Chinese. In education, alphabetic language (English, French, Spanish) learners can calculate words and sentences in mathematics (abacus calculation, mental arithmetic, calculation), and learn words and sentences of languages in detail. Math (abacus calculation, mental arithmetic, calculation) learners can study alphabetic languages (English, French, Spanish) not in a tedious repetition of calculation but in a mathematical learning process.
