Technical scheme
According to an aspect of the present utility model, above and other purpose can be realized by providing a kind of battery cell, this battery cell is configured to have following structure: including anelectrode, negative electrode and the electrode assemblie of separator arranged between anelectrode and negative electrode are installed in the battery case being made up of the laminate including resin bed and metal level, wherein this battery cell is configured to have the irregular structure including at least five limit when viewed from above, and in the positive electrode lead of battery cell and negative electrode lead different edge in these limits from the battery case of battery cell outwardly.
I.e., it is configured to have the irregular structure including such as five or more polygon, multiple limit according to battery cell of the present utility model, and positive electrode lead and negative electrode lead are disposed at different edge, it are therefore prevented from contact conductor and contact with each other due to external force or interfering with each other.
It addition, battery cell can be configured with following structure, in the structure shown here, positive electrode lead and negative electrode lead are prominent at the limit of different directions；It is possible to realize in different directions the electrical connection of each contact conductor in contact conductor.Result, it is possible to can by battery cell and circuit, device electric connection construction for having various structure.
This irregular structure can be the polygonized structure including straight limit.Alternately, constituting at least one in the limit of this irregular structure can be bending.
An outer peripheral part for battery cell can be round shape, in order to corresponding to the limit of this bending.
When viewed from above, these limits constitute the outward flange of the battery case that the outer surface to battery cell is defined.That is, when battery cell viewed from above, the outer surface of battery is corresponding to the outward flange of battery case.
These limits can include positive electrode lead from its first prominent limit, negative electrode lead is from its second prominent limit with except other limit on the first limit and the second limit.
Positive electrode lead vertically highlights from the first limit, and negative electrode lead vertically highlights from the second limit.
In this structure, positive electrode lead and negative electrode lead are respectively from being the first limit of different edge and the second limit highlights.Therefore, when external force is applied to battery cell, it is therefore prevented that positive electrode lead and negative electrode lead contact with each other.
It addition, in above structure, positive electrode lead and negative electrode lead are positioned at different limits and make positive electrode lead and negative electrode lead be spaced apart from each other.Therefore, in the activation process of battery cell, i.e. in the initial charge and discharge process of battery cell, it is possible to prevent positive electrode lead and negative electrode lead due to interfering with each other for the device of induced current to positive electrode lead and negative electrode lead.
