Lithium secondary battery |
| abstract |
A lithium secondary cell (1) includes a cell case (6) that includes a covering region (67) and an outer peripheral region (68). The covering region (67) is a rectangular region overlaid on the positive electrode (2), the separator (4), and the negative electrode (3) in a direction of superposition. The outer peripheral region (68) is a rectangular frame-like region surrounding the covering region (67). The outer peripheral region (68) includes first regions (681) that are band-like regions extending respectively along a pair of long sides (691). In the first regions (681), a first sheet portion (65) and a second sheet portion (66) are bonded together. A second region (682) is a band-like region extending along the covering region (67) between the covering region (67) and at least one first region (681) out of the pair of first regions (681). In the second region (682), the first sheet portion (65) and the second sheet portion (66) are in contact with or in close proximity to each other without being bonded together. This suppresses leakage of an electrolytic solution (5) to outside the lithium secondary cell (1). |
