Abstract

The present invention provides a battery pack and its fabricating method, a battery and an electronic device. The battery pack provided by the present invention comprises: an outer package, which is in a laminated form and has a conductive layer therein; and a battery cell, which has a positive electrode terminal and a negative electrode terminal and is housed in the outer package, wherein, the positive electrode terminal or the negative electrode terminal of the battery cell is electrically connected to said conductive layer at the part led out from the outer package. With the battery pack and its fabricating method provided by the present invention, the influence of electrostatic discharge can be eliminated with a more simple structure.

First claim

The invention is claimed as follows:

1. A battery pack comprising:
an outer package including an adhesive layer, a conductive layer and a protective layer from an inner side to an outer side, respectively; and
a battery cell, which has a positive electrode terminal and a negative electrode terminal and is housed in the outer package,
wherein the positive electrode terminal or the negative electrode terminal of the battery cell is electrically connected to said conductive layer at the part led out from the outer package by a conductive binder,
wherein the conductive binder extends onto an outer side of the protective layer,
wherein the positive electrode terminal or the negative electrode terminal of the battery cell is partially covered with a sealing layer on the inner side of the adhesive layer at the part led out from the outer package, and
wherein the sealing layer and the conductive binder define a gap therebetween.

2. A battery comprising:
a front cover unit;
a battery pack; and
a back cover unit,
wherein the battery pack comprises an outer package including an adhesive layer, a conductive layer and a protective layer from an inner side to an outer side, respectively, and a battery cell housed in the outer package,
wherein a positive electrode terminal or a negative electrode terminal of the battery cell is electrically connected to said conductive layer at the part led out from the outer package by a conductive binder,
wherein the conductive binder extends onto an outer side of the protective layer,
wherein the positive electrode terminal or the negative electrode terminal of the battery cell is partially covered with a sealing layer on the inner side of the adhesive layer at the part led out from the outer package, and
wherein the sealing layer and the conductive binder define a gap therebetween.

3. An electronic device comprising:
an electronic device body; and
a battery supplying power to the electronic device body,
wherein the battery comprises a front cover unit, a battery pack and a back cover unit, and
wherein the battery pack comprises an outer package including an adhesive layer, a conductive layer and a protective layer from an inner side to an outer side, respectively, and a battery cell housed in the outer package,
wherein a positive electrode terminal or a negative electrode terminal of the battery cell is electrically connected to said conductive layer at the part led out from the outer package by a conductive binder,
wherein the conductive binder extends onto an outer side of the protective layer,
wherein the positive electrode terminal or the negative electrode terminal of the battery cell is partially covered with a sealing layer on the inner side of the adhesive layer at the part led out from the outer package, and
wherein the sealing layer and the conductive binder define a gap therebetween.
