The invention discloses a gluing structure
battery cell with an embedded tab, a fabrication method of the gluing structure
battery cell and a
lithium battery, and belongs to the technical field of
lithium batteries. The
battery cell comprises a positive
electrode plate, a negative
electrode plate and a diaphragm and also comprises a positive
electrode tab and a negative electrode tab, wherein thediaphragm is arranged between the positive electrode plate and the negative electrode plate, the positive electrode tab is arranged on each positive electrode plate, the negative electrode tab is arranged on each negative electrode plate, a
tail-end edge of the positive electrode tab, a
tail-end edge of the negative electrode tab and
tail ends of the electrode plate are maintained at the same horizontal surface, one of the tabs in the positive electrode tabs is connected with a first
nickel sheet, one of the tabs in the negative electrode tabs is connected with a second
nickel sheet, and the first
nickel sheet and the second nickel sheet extend out of the edges of the electrode plates and are used for leading out the tabs. By the battery
cell, the
mass energy density of the battery can beeffectively improved, moreover, malposition and loosening of the positive electrode plate and the negative electrode plate also can be effectively prevented, the contact between the electrode plates is improved, and the stability and the safety of the battery are favorably improved.
