Abstract
The invention belongs to the field of electrochemical batteries and particularly relates to an electrochemical battery. The electrochemical battery comprises a bare battery cell, an electrolyte solution and an external package, wherein a rubber tape layer is arranged between the bare battery cell and the external package; the rubber tape layer comprises a base material and a bonding layer; the base material is 0.5-500 microns in thickness h1, and when the base material is heated to above 45 DEG C, the base material shows the bonding performance; the bonding layer is 0.5-500 microns in thickness h2, and when the temperature is lower than or equal to 45 DEG C, the bonding layer shows the bonding performance; and a rubber tape (before glue overflow) covers 2-90% of the surface area of the bare battery cell. The electrochemical battery has the advantages that the bonding layer has bonding force at a relatively low temperature, so that the operation is convenient when the battery cell is manufactured; the bonding layer is pasted to the surface of the bare battery cell or/and the inner side of the external package; and the base material shows bonding force after being heated, so that a bonding area between the bare battery cell and the external package can be effectively enlarged, the coverage area of the rubber tape on the bare battery cell is reduced, the glue consumption is reduced, the total amount of overflowed glue is reduced, and a mucilage glue layer is prevented from being diffused to a degassing packaging edge to influence the packaging effect.
