Abstract: The present invention relates to an electrode assembly having fiber-shaped structures, and a battery including the same. According to one embodiment of the present invention, the electrode assembly comprises: a first electrode having one or two or more first fiber-shaped structures that have either a positive or negative pole; and a second electrode having one or two or more second fiber-shaped structures that have a different polarity from the structures and enclose said first structures in a spiral manner.

Abstract: The present invention relates to a battery having an electrode structure using metal fiber and a preparation method of an electrode structure. A preparation method of an electrode structure, according to one embodiment of the present invention, includes a step for providing one or more metal fibers forming a conductive network; a step for providing particle compositions including electrical active materials of a particle shape; a step for mixing the metal fibers and the particle compositions; and a step for compressing the mixed metal fibers and the particle compositions.

Abstract: The present invention relates to a battery having an electrode structure using long metal fibers, and to a production method therefor. According to one embodiment of the present invention, the battery has an electrode structure comprising: an electrically-conductive network which is formed by physical connection or chemical bonding between one or more long metal fibers; and a first electrically active material which is bound to the electrically-conductive network.

Abstract: The present invention relates to an electrode assembly comprising fiber-shaped structures. The electrode assembly for a battery according to one embodiment of the present invention comprises: a first electrode including a plurality of first fiber-shaped structures extending in a first direction; a second electrode including a plurality of second fiber-shaped structures which extend in a second direction other than the first direction, and the polarities of which are different from the polarities of the first structures; and a first separator film interposed between the first structures and the second structures which intersect with each other, so as to separate the first structures and the second structures from each other.

Abstract: A chair includes at least one support frame having two opposite side rails, a plurality of connectors mounted in each of the side rails of the support frame, and a plurality of elastic cords each mounted between the side rails of the support frame and each having two opposite ends each attached to one of the connectors. Each of the side rails of the support frame has a hollow inside provided with a slideway and has a side provided with a guide slot. Thus, each of the connectors is fully hidden in the slideway and the guide slot of each of the two rails of the support frame so that each of the connectors will not be exposed outwardly from the support frame to enhance the outer appearance and safety of the chair.

Abstract: A method for forming an artificial fingernail on a natural fingernail comprises the steps of preparing a water-soluble polyvinyl alcohol solution; applying the solution on natural fingernail 2 to form an adhesive layer 3 thereon; putting artificial fingernail 4 on natural fingernail 2 through adhesive layer 3; and curing adhesive layer 3. Although fully cured, adhesive layer 3 can be dissolved and softened in water so that artificial fingernail 4 can easily be removed from natural fingernail 2 in a short time.

Abstract: A luminous toy capable of emitting light at any time anywhere without having to worry about a power shortage and failing to turn off a switch and capable of preventing environmental pollution. The luminous toy includes a toy body provided with a piezoelectric element which induces a voltage when it is strained, a rectifying circuit for rectifying the voltage generated from the piezoelectric element, a capacitor for smoothing the voltage rectified by the rectifying circuit and a luminous element connected in parallel to the capacitor. The luminous toy also includes a strain generating mechanism for generating strain for straining the piezoelectric element.

Abstract: A perfumer structure with an optically controlled night lamp is disclosed. The perfumer structure includes a heat conductor wrapped by a heat conductive and fireproof plastic material for generating heat to vaporize a solid perfume and uniformly disperse perfume gas. The night lamp is disposed in the perfumer structure and controlled by an optically sensitive element which turns on/off the lamp according to the ambient illumination. The perfumer structure is powered on via a single power plug and has both the functions of dispersing perfume gas to clean the air and illuminating at night.
