According to an embodiment, the negative-electrode substrate 328 may be referred to as a second substrate, and the negative-electrode mixture 329 may be referred to as a second mixture.
According to an embodiment, the separator 301 may be a non-conductive porous body which physically separates the first electrode 310 and the second electrode 320, and has a pore enabling a designated material (e.g., a lithium (Li) ion) to move therein. According to an embodiment, the separator 301 may be made of a synthetic resin (e.g., polyethylene or polypropylene).
According to an embodiment, the separator 301 (e.g., the separator assembly) may include multiple separators 330 and 340. For example, the separator 301 may include a first separator 330 and a second separator 340. The second separator 340 may be spaced apart from the first separator 330.
According to an embodiment, the battery 300 may have a stacked shape. For example, the first electrode 310, the second electrode 320, the first separator 330, and the second separator 340 may be formed to have a stacked shape. According to an embodiment, one (e.g., the second separator 340) of the separator 301, one (e.g., the first oxidation electrode 3201) of the multiple second electrodes 320, one (e.g., the first reduction electrode 3101) of the multiple first electrodes 310, and the other (e.g., the first separator 330) of the separator 301 may be sequentially stacked.
According to an embodiment, the separator 301 may include multiple separators (e.g., the first separator 330 and the second separator 340). According to an embodiment, an electrode (e.g., the first electrode 310 or the second electrode 320) may be positioned between the first separator 330 and the second separator 340. The first separator 330 and the second separator 340 may prevent direct contact between the first electrode 310 and the second electrode 320. By preventing direct contact between the first electrode 310 and the second electrode 320, a short circuit of the battery 300 may be prevented.
According to an embodiment, the first separator 330 and the second separator 340 may be wound in a state of being arranged in different directions. For example, the first separator 330 may be wound after being disposed substantially perpendicular to the second separator 340. According to an embodiment, the second separator 340 may be disposed along a second direction (e.g., the +X direction), and may be wound around a first direction (e.g., the +Y direction). For example, the second separator 340 may be wound to surround the first direction (the +Y direction). The first separator 330 may be disposed along the first direction, and may be wound around the second direction. For example, the first separator 330 may be wound to surround the second direction (e.g., the +X direction). In various embodiments of the document, the state, in which the first separator 330 is disposed along the first direction (e.g., the +Y direction), may be referred to as a state in which the length in the first direction (e.g., the +Y direction) of the first separator 330 is longer than the length in the second direction (e.g., the +X direction). For example, the first separator 330 configured to be folded in the first direction (e.g., the +Y direction) or a third direction (e.g., the −Y direction) opposite to the first direction. For example, the second separator 340 configured to be folded in a second direction (e.g., the +X direction) perpendicular to the first direction, or a fourth direction (e.g., the −X direction) opposite to the second direction.
According to an embodiment, a first length of the first separator 330 and a second length of the second separator 340 may be different. For example, in case that the battery 300 includes a substantially rectangular parallelepiped shape, the length in first direction (e.g., the +Y direction) of an electrode (e.g., the first electrode 310 and the second electrode 320) may be different from the length in the second direction (e.g., the +X direction). According to an embodiment, the length in the first direction (e.g., the +Y direction) of the first electrode 310 and the second electrode 320 may be longer than the length in the second direction (e.g., the +X direction) of the first electrode 310 and the second electrode 320). The first length of the first separator 330 wound around the second direction (e.g., the +X direction) may be longer than the second length of the second separator 340 wound around the first direction (e.g., the +Y direction).

According to an embodiment, the first tab 317 may be referred to as a positive-electrode tab. The second tab 327 may be referred to as a negative-electrode tab.
According to an embodiment, one of the first separator 330 or the second separator 340 may accommodate the first tab 317 of the first electrode 310 and/or the second tab 327 of the second electrode 320. For example, the separators 330 and 340 may surround at least a part of the tabs 317 and 327. Referring to an embodiment (e.g.,
