[0041] Here, some embodiments of the present disclosure will be described in further detail with reference to the accompanying drawings. The terms or words used in this specification and claims should not be interpreted as limited to the usual or dictionary meanings, but should be interpreted as meanings and concepts consistent with the technical concept of the present disclosure based on the principle that the inventor can be his / her own lexicon compiler to appropriately define the concepts of the terms.

[0042] The embodiments described in this specification and the configurations shown in the accompanying drawings are provided as some example embodiments of the present disclosure, and do not necessarily represent all technical ideas, aspects and features of the present disclosure. Therefore, it will be understood that when submitting this application, there may be various equivalents and modifications that can replace or modify the embodiments described herein.

[0043] It will be understood that when an element or layer is referred to as being "on," "connected to," or "coupled to" another element or layer, it may be directly on, directly connected to, or directly coupled to the other element or layer, or one or more intervening elements or layers may also be present. When an element or layer is referred to as being "directly on," "directly connected to," or "directly coupled to" another element or layer, there are no intervening elements or layers. For example, when a first element is described as being "coupled to" or "coupled to" a second element, the first element may be directly coupled to or directly coupled to the second element, or the first element may be indirectly coupled to or indirectly coupled to the second element via one or more intervening elements.

[0044] In the figure, for the sake of clarity, the sizes of various elements, layers, etc. may be exaggerated. The same reference numerals represent the same or similar elements. As used herein, the term "and / or" includes any combination and all combinations of one or more of the relevant listed items. In addition, when describing the embodiments of the present disclosure, the use of "may" relates to "one or more embodiments of the present disclosure". Expressions such as "at least one (kind / person) in ... " and "any one (kind / person) in ... " modify the entire row of elements after a row of elements, without modifying the individual elements of the row. When phrases such as "at least one (kind / person) in A, B and C", "at least one (kind / person) in A, B or C", "at least one (kind / person) selected from the group of A, B and C" or "at least one (kind / person) selected from A, B and C" are used to specify a row of elements A, B and C, the phrase can refer to any and all suitable combinations or subsets of A, B and C, such as A, B, C, A and B, A and C, B and C, or A and B and C. As used herein, the term "use" and variations thereof may be considered synonymous with the term "utilize" and variations thereof, respectively. As used herein, the terms "substantially," "about," and similar terms are used as terms of approximation rather than as terms of degree, and are intended to account for the inherent variations in measurements or calculations that one of ordinary skill in the art would recognize.

[0045] It will be understood that although the terms "first", "second", "third", etc. may be used herein to describe various elements, components, regions, layers and / or parts, these elements, components, regions, layers and / or parts will not be limited by these terms. These terms are used to distinguish one element, component, region, layer or part from another element, component, region, layer or part. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer or part discussed below may be referred to as a second element, component, region, layer or part.

[0046] For ease of description, spatially relative terms such as "under", "below", "lower", "above", "upper", etc. may be used herein to describe the relationship of one element or feature to another element or features as shown in the figure. It will be understood that, in addition to the orientation depicted in the figure, the spatially relative terms are intended to cover different orientations of the device in use or operation. For example, if the device in the figure is turned over, the elements described as "under" or "below" other elements or features will then be oriented to be "above" or "above" the other elements or features. Therefore, the term "under" can cover both above and below. The device can be oriented otherwise (e.g., rotated 90 degrees or in other orientations), and the spatially relative descriptors used here should be interpreted accordingly.

[0047] The terms used herein are for the purpose of describing the embodiments of the present disclosure, and are not intended to limit the present disclosure. As used herein, unless the context clearly indicates otherwise, the singular forms "one" and "one (kind / person)" are also intended to include plural forms. It will also be understood that when the terms "include", "comprise" and / or its variations are used in this specification, the features, wholes, steps, operations, elements and / or components stated are indicated, but the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or their groups are not excluded.

[0048] In addition, any numerical range disclosed and / or described herein is intended to include all sub-ranges of the same numerical precision contained in the described range. For example, the range of "1.0 to 10.0" is intended to include all sub-ranges between the described minimum value 1.0 and the described maximum value 10.0 (and including the described minimum value 1.0 and the described maximum value 10.0), that is, having a minimum value equal to or greater than 1.0 and a maximum value equal to or less than 10.0, such as 2.4 to 7.6. Any maximum numerical limit described here is intended to include all lower numerical limits contained therein, and any minimum numerical limit described in this specification is intended to include all higher numerical limits contained therein. Therefore, the applicant reserves the right to modify this specification and claims to explicitly describe any sub-range contained in the scope explicitly described here.

[0049] Referring to two compared elements, features, etc. as "the same" may mean that they are the same or substantially the same. Thus, the phrases "the same" or "substantially the same" may include situations with deviations that are considered low in the art (e.g., 5% or less). Additionally, when a parameter is referred to as being uniform in a given area, it may mean that it is uniform with respect to an average value.

[0050] Throughout the specification, unless otherwise stated, each element may be in the singular or in the plural.

[0051] When any element is referred to as being disposed (or positioned or located) "above (or below)" or "on (or below)" a component, it may mean that the arbitrary element is placed in contact with the upper (or lower) surface of the component, and may also mean that another component may be placed between the component and the arbitrary element disposed (or positioned or located) on (or below) the component.

[0052] In addition, it will be understood that when an element is referred to as being "coupled," "linked," or "connected" to another element, the elements may be directly "coupled," "linked," or "connected" to each other, or one or more intervening elements may be present therebetween through which the element may be "coupled," "linked," or "connected" to the other element. In addition, when a component is referred to as being "electrically coupled" to another component, the component may be directly electrically connected to the other component, or one or more intervening components may be present therebetween so that the component and the other component are indirectly electrically connected to each other.

[0053] Throughout the specification, when "A and / or B" is stated, it means A, B, or A and B unless otherwise stated. That is, "and / or" includes any combination or all combinations of the listed multiple items. When "C to D" is stated, it means C or greater and D or less unless otherwise stated.

The insulating member 220 may be installed or arranged inside the fence 211. The insulating member 220 may be arranged to face the third surface 211c and the plurality of second surfaces 211b of the fence 211, and in an embodiment, may be coupled to the fence 211 by bolts. In an embodiment, the insulating member 220 may be arranged to be spaced apart from the third surface 211c and the plurality of second surfaces 211b.

[0076] The insulating member 220 may be generally or approximately formed in a plate shape. The insulating member 220 may prevent or substantially prevent a short circuit that may occur when the battery 10 treated with salt water contacts the fence 211. In an embodiment, the insulating member 220 may be made of a Bakelite material or the like.

[0077] The insulating member 220 may be provided with a second opening 220a. The second opening 220a may be formed to pass through the insulating member 220 in a thickness direction of the insulating member 220. A plurality of second openings 220a may be arranged to be spaced apart from each other in the insulating member 220.

[0078] The second opening 220a formed in the insulating member 220 may be disposed at a position corresponding to the first opening 210a formed in the fence 211. In an embodiment, the first opening 210a and the second opening 220a may be formed to have the same diameter. The first opening 210a and the second opening 220a may be communicated with each other. Therefore, the brine in the brine tank 100 may sequentially pass through the first opening 210a and the second opening 220a, and may be introduced into the fence 211.

[0079] The salt water stored in the salt water tank 100 can be quickly introduced into the fence 211 while forming turbulence through the second opening 220a formed in the insulating member 220. Therefore, while the battery processing container 200 according to the present disclosure sinks to the bottom of the salt water tank 100, the battery processing container 200 can sink stably without rotating or turning over.
