As background art, the fixing method of the battery on the electric equipment at present mainly includes three types of wrapping films, easy-to-pull adhesive tapes and double-sided adhesive tapes. The inventor researches and discovers that the wrapping film and the easy-to-pull adhesive can better detach the battery from the electric equipment but cause large loss on the energy density of the battery, the double-sided adhesive has small loss on the energy density of the battery but is difficult to detach the battery from the host, and if the double-sided adhesive is not operated properly, the battery is possibly scrapped and the safety risk is possibly caused.

This application embodiment, electric core surface is equipped with coating 20, when scribbling solid fixed glue 30 to electric core coating 20 surface, can reduce the area of contact of solid fixed glue 30 and electric core, can improve the energy density loss that solid fixed glue direct contact electric core caused here. In addition, the coating 20 is made of a material which is easily soluble in a solvent, and when the battery is disassembled from the electric equipment, the fixing glue and the battery can be separated by dissolving the coating 20 by the solvent, so that the disassembly simplicity can be improved.
With respect to the coating 20, in some embodiments, the shape of the coating 20 is adapted to the shape of the bezel of the powered device or the shape of the mounting glue. In some examples, the fixing adhesive used is a double-sided adhesive tape, the shape of the double-sided adhesive tape is rectangular, and then the coating 20 is also designed to be rectangular, the double-sided adhesive tape is circular, the coating 20 is also designed to be circular, the double-sided adhesive tape is a hollow shape, and the coating 20 is also designed to be a corresponding hollow shape. Fig. 2 is a schematic structural diagram of 4 cells with different shapes of the coating 20 in some embodiments.
In some embodiments, the area of the coating 20 is greater than or equal to the area of the securing glue used to attach to the coating 20. Here, when the battery is fixed to the electric device by the fixing adhesive so that the fixing adhesive does not exceed the circumferential edge of the coating 20 for attachment, it is more advantageous to reduce the contact area between the fixing adhesive 30 and the battery.
In some embodiments, the thickness of the coating 20 is in the micron range. In some examples, the coating 20 has a thickness of 2 μm to 50 μm. The inventor researches and discovers that when the thickness of the coating 20 is micron-sized, the fixing glue 30 can be prevented from being in direct contact with the battery cell, and the thinner coating 20 has little influence on the energy density of the battery cell.
In some embodiments, referring to fig. 2d, the coating 20 has grooves for drainage. The setting is used for the recess of drainage to be favorable to when dismantling electric core and dissolve coating 20, with solvent drainage to coating 20 in, the contact of increase solvent and coating 20 for coating 20's dissolving speed.
The width of the grooves may be less than a preset value, and in some examples, the width of each groove is 0.5mm to 3 mm. Therefore, solvent drainage can be realized, contact between the fixing glue and the battery cell 10 can be reduced, and the influence on the energy density of the battery can be reduced.
In some embodiments, the coating layer 20 may be made of a material that is easily soluble in an organic solvent, but is not limited thereto, and an inorganic solvent may be used. The organic solvent belongs to the common solvents in the field, and the inventor researches and finds that when the organic solvent is adopted, the coating has better dissolving effect and is beneficial to disassembly. In some examples, the coating layer 20 may be made of a material that is easily soluble in an organic solvent such as ethanol or ethyl acetate, i.e., the organic solvent may be ethanol or ethyl acetate, but is not limited thereto. In some examples, the coating 20 is made of epoxy, polyurethane, polypropylene, or the like, which is easily soluble in organic solvents, but is not limited thereto.
In some embodiments, the first surface includes at least one surface where the cell 10 has the largest area. In this case, when the coating 20 is designed on the surface of the battery cell 10 with the largest area, more fixing glue can be attached, which is beneficial to fixing the battery to the electric equipment.

For example, during concrete implementation, a double-sided adhesive tape can be adhered to the finished product battery core, and when the battery is assembled on the equipment, the other side of the double-sided adhesive tape is torn off, so that the assembly convenience can be improved.
In some embodiments, the fixing glue 30 is a double-sided glue or glue, but is not limited thereto. When the fixing adhesive 30 is a double-sided adhesive, the influence on the energy density of the battery cell is small.
In some embodiments, referring to fig. 3 and 4, the fixing glue 30 does not extend beyond the peripheral edge of the coating 20. Therefore, the contact area between the fixing glue 30 and the battery is reduced, and the influence on the energy density of the battery is reduced.
