Claim 13:
14. A manufacturing system of battery cell, comprising:
a first assembling apparatus, configured to provide an electrode assembly, wherein the electrode assembly comprises a first electrode plate, a second electrode plate, and a separator, wherein the first electrode plate and the second electrode plate each has a coated area and an uncoated area, a part of the electrode assembly corresponding to the coated areas of the first electrode plate and the second electrode plate being a body portion, the uncoated area of the first electrode plate or the second electrode plate forming a tab, and the separator being configured to isolate the first electrode plate from the second electrode plate;
a second assembling apparatus, configured to place the electrode assembly having the body portion and the tab into a housing having an opening, wherein the tab extends from an end of the body portion to the opening; and
a third assembling apparatus, configured to assemble an end cover assembly having an end cover and a first insulator with the housing, wherein the end cover covers the opening and is connected to the housing, the first insulator is located on a side of the end cover closer to inside of the housing, the first insulator has a concave portion, the tab being accommodated in the concave portion, and at least one part of an inner wall of the concave portion being disposed surrounding a periphery of the tab, wherein the battery cell comprises a connecting piece comprising a first connecting portion and a second connecting portion, wherein, the first connecting portion is located between the first insulator and the electrode assembly and is located in the concave portion; and, wherein
the electrode assembly further comprises a second insulator, and the second insulator is disposed surrounding an abutting area between the first insulator and the tab to isolate the abutting area from the housing;
wherein the second insulator abuts against an outer side surface of the first insulator facing toward an outer side surface of the housing; and
the battery cell further comprises a third insulator, the third insulator is disposed surrounding the second insulator and covers a transition area between the second insulator and the outer side surface.
