Description

Bulkhead apparatus and graphite furnace containing the same The present invention relates to a partition device and a graphite furnace including the same. The four major components of a secondary battery are commonly referred to as the cathode, anode, electrolyte, and separator. Among these, the cathode, anode, and separator are considered core materials because they determine the overall performance of the secondary battery. Secondary batteries, such as lithium-ion batteries, generally generate electricity through the chemical reaction of lithium ions moving between the cathode and the anode. Here, while the cathode determines the overall capacity and voltage of the battery, the anode plays the role of storing and releasing lithium ions from the cathode. As such, the anode material, which stores lithium ions, affects the battery's charging speed and lifespan. It is no exaggeration to say that battery performance varies depending on the performance of the anode material. Furthermore, as the development of cathode materials has recently reached its limits, the development of anode material technology has become an even more critical factor in improving battery performance. The cathode material production facility includes a furnace that grinds and heats raw material powder. A partition wall is installed inside a conventional graphite furnace. However, there is a problem in that the electrode is damaged when it collides with the partition wall during the installation process. FIG. 1 is a perspective view showing a partition device according to one embodiment of the present invention installed in a graphite furnace. FIG. 2 is an exploded perspective view illustrating a partition device and a furnace body according to one embodiment of the present invention of FIG. 1. FIG. 3 is a plan view showing a state in which a partition device according to one embodiment of the present invention is installed in a furnace body. FIG. 4 is a perspective view showing the first bulkhead unit extracted from the bulkhead device of FIG. 2. FIG. 5 is a front view illustrating a bulkhead device according to one embodiment of the present invention. The embodiments of the present invention are provided to more fully explain the invention to those skilled in the art, and the following embodiments may be modified in various different forms, and the scope of the invention is not limited to the following embodiments. Rather, these embodiments are provided to make the disclosure more faithful and complete and to fully convey the spirit of the invention to those skilled in the art. Additionally, in the drawings below, the thickness or size of each layer is exaggerated for convenience and clarity of explanation, and like reference numerals in the drawings refer to like elements. As used herein, the term "and/or" includes any one of the listed items and all combinations of one or more thereof. Furthermore, in this specification, the meaning of "connected" refers not only to cases where Member A and Member B are directly connected, but also to cases where Member C is interposed between Member A and Member B so that Member A and Member B are indirectly connected. The terms used herein are for describing specific embodiments and are not intended to limit the invention. As used herein, the singular form may include the plural form unless the context clearly indicates otherwise. Additionally, as used herein, "comprise, include" and/or "comprising, including" specify the presence of the mentioned features, numbers, steps, actions, parts, elements, and/or groups thereof, and do not exclude the presence or addition of one or more other features, numbers, actions, parts, elements, and/or groups. Although terms such as "first," "second," etc. are used in this specification to describe various components, parts, regions, layers, and/or parts, it is obvious that these components, parts, regions, layers, and/or parts should not be limited by these terms. These terms are used solely to distinguish one component, part, region, layer, or part from another region, layer, or part. Accordingly, the first component, part, region, layer, or part described below may refer to the second component, part, region, layer, or part without departing from the teachings of the present invention. Additionally, spatial terms such as "beneath," "below," "lower," "above," and "upper" may be used to facilitate understanding of one element or feature depicted in the drawings and another element or feature. These spatial terms are intended to facilitate understanding of the invention according to various process or usage conditions of the invention and are not intended to limit the invention. For example, if an element or feature in the drawings is inverted, an element or feature described as "beneath" or "below" becomes "upper" or "on top." Therefore, "beneath" is a concept that encompasses "upper" or "below." Before describing the graphite furnace according to one embodiment o
