Problems solved by technology

[0003] like figure 1 As shown, in the production process of the existing battery 200, the tab shaping pressing block 300 is pressed against the tab 210, and the part that is pressed against the tab 210 causes station interference between the glue sticking mechanism and the tab shaping pressing block 300. , resulting in the glue-applying mechanism being unable to apply glue to part of the tab 210, which in turn causes the part of the tab 210 to be exposed in the packaging bag, and the exposed part of the tab 210 is easy to pierce the packaging bag and cause the battery to corrode, posing a safety hazard

Abstract

The embodiment of the invention discloses a battery cell and an electronic device. The battery cell comprises an electrode assembly and a first conductive unit, the electrode assembly comprises a plurality of first pole pieces, a plurality of second pole pieces and diaphragms, the first pole pieces and the second pole pieces are alternately stacked, the diaphragms comprise a first diaphragm and a plurality of second diaphragms, and in the thickness direction of the electrode assembly, the first pole pieces are located at one sides of the first diaphragms, and each second diaphragm is arranged between the adjacent first pole piece and second pole piece. The first diaphragm comprises a main body part and a protection part extending out of the edge of the main body part, and the protection part covers the first conductive unit and prevents the exposed part of the first conductive unit from puncturing the packaging bag.

Description

technical field [0001] The embodiments of the present application relate to the technical field of batteries, and in particular, to a battery cell and an electronic device. Background technique [0002] Lithium-ion batteries have become the power source of choice for consumer portable electronics. With the rapid development of mobile communication equipment and multimedia equipment, people have strict requirements on the safety performance of lithium-ion batteries used in these equipment. [0003] Such as figure 1 As shown, in the production process of the existing battery 200, the tab shaping pressing block 300 is pressed against the tab 210, and the part that is pressed against the tab 210 causes station interference between the glue sticking mechanism and the tab shaping pressing block 300. , resulting in the glue-applying mechanism being unable to apply glue to part of the tab 210, which in turn causes the part of the tab 210 to be exposed in the packaging bag, and the...
