[0025] The terminology used herein is for the purpose of describing a particular exemplary configuration only and is not restrictive. As used herein, the singular articles “a,” “an,” and “the” may also be intended to include plural forms unless the context clearly indicates otherwise. The terms “comprising,” “including,” “containing,” and “having” are inclusive and thus specify the presence of a feature, step, operation, element, and / or component, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or groups thereof. The method steps, processes, and operations described herein should not be construed as requiring them to be performed in the specific order discussed or shown, unless specifically identified as such. Additional or alternative steps may be employed.

[0026] When an element or layer is described as being “on,” “joined to,” “connected to,” “attached to,” or “linked to” another element or layer, it may be directly on, joined to, attached to, or linked to the other element or layer, or there may be intermediate elements or layers present. Conversely, when an element is described as being “directly on,” “directly joined to,” “directly connected to,” “directly attached to,” or “directly linked to” another element or layer, there may be no intermediate elements or layers present. Other terms used to describe relationships between elements should be interpreted in a similar manner (e.g., “between” vs. “directly between,” “adjacent” vs. “directly adjacent,” etc.). As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items.

[0027] This document may use the terms “first,” “second,” “third,” etc., to describe various elements, components, regions, layers, and / or parts. These elements, components, regions, layers, and / or parts should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or part from another. Unless the context clearly indicates otherwise, terms such as “first,” “second,” and other numerical terms do not imply order or sequence. Therefore, without departing from the teachings of the example configuration, the first element, component, region, layer, or part discussed below may be referred to as the second element, component, region, layer, or part.

The prismatic can 28 includes a height H disposed between the bottom side 38 and a top side or cover 44 spaced apart from the bottom side 38. The cover 44 extends between the first side 30, the second side 32, the first end 34, and the second end 36, and is joined or otherwise attached to the first side 30, the second side 32, the first end 34, and the second end 36 via welding or another method commonly used in the automotive industry. In at least some embodiments, the cover 44 may be assembled with the battery internal components 42 before being attached or otherwise coupled to the rest of the prismatic can 28.

[0039] refer to Figure 5 The prismatic can 28 may need to be cut open after assembly or operation for testing, recycling, or another purpose. Some existing methods of doing so are time-consuming or may damage parts of the prismatic can and / or the internal components of the battery. According to at least some aspects of this disclosure, an apparatus 100 is provided, configured to cut one or more portions of the prismatic can 28 or another type of battery cell used in the automotive industry.

Figure 8A The first cutting tool 186 includes a mating wall 194 that extends between a first end 190 and a second end 192 and is configured to engage with a first mating surface 158 or a second mating surface 160. In other words, refer to... Figure 9 When the retainer 144 and / or the cutting tool 146 is driven toward the base 102 relative to the first axis A1, the first engagement surface 158 and the second engagement surface 160 of the tool guide 140 will act on the engagement wall 194 of the first and second cutting tools 186, 188, and cause the first and second cutting tools 186, 188 to converge relative to the second axis A2.

[0048] refer to Figure 8A and 8BThe first and second cutting tools 186, 188 include a channel 196 extending between a first end 190 and a second end 192. The first cutting tool 186 and the second cutting tool 188 may be arranged in a retainer 144 such that the channels 196 are opposite each other and face the cutting area 156. A blade 198 may be arranged in the channel 196 and extend between the first end 190 and the second end 192. The blade 198 has a first end 198a and a second end 198b spaced apart from the first end 198a. The second end 198b may be defined by, for example, one or more teeth. In at least some embodiments, reference is made to... Figure 8A The insert 200 can be arranged in the channel 196 and orient the blade 198 between a first end 190 and a second end 192. More specifically, the first end 198a can be disposed within a portion of the insert 202, and the second end 198b protrudes from the insert 202, as shown below. Figure 8A As shown.
