The example of the consistent apparatus and method of some aspects be described in detail in claims, the disclosure.
Fig. 1 is a kind of encapsulation schematic diagram of core strueture in correlation technique；Fig. 2 is a kind of battery core knot in correlation technique
The schematic diagram of structure.As shown in Figs. 1-2, for the core strueture 1 ' using " Soft Roll " structure, generally use aluminum plastic film A1 is to inside
The energy storing structures A2 such as electrolyte wrapped up, then except " pocket that aluminum plastic film A1 is formed energy storing structure A2 on the left of Fig. 1
Outside bottom ", corresponding first side opening K1, the second side opening K2 and top can be respectively formed on remaining downside, upside, right side
Portion opening K3；Then, by the way that aluminum plastic film A1 is sealed at the first side opening K1 and the second side opening K2, two can be obtained
A side sealing, and by the way that aluminum plastic film A1 is sealed at open top K3, top edge sealing 2 ' can be obtained, so as to fulfill right
The sealed envelope of energy storing structure A2.
Wherein, it is outwardly formed from the top surface 11 ' (right flank of core strueture 1 ' i.e. shown in Fig. 2) of core strueture 1 ' above-mentioned
Top edge sealing 2 ', the end 21 ' of the top edge sealing 2 ' is perpendicular to top surface 11 ', and the head end 22 ' of the top edge sealing 2 ' and the end
The direction at end 21 ' is consistent, such as the direction can be x-axis direction shown in Fig. 2, and the x-axis direction is residing perpendicular to top surface 11 '
Y-axis direction.Meanwhile the head end 22 ' of top edge sealing 2 ' also stretches out the lug 3 ' of the core strueture 1 ' further out, for even
It is connected to external equipment or external equipment is connected to by battery protecting plate.
As it can be seen that when top edge sealing 2 ' extends and along the x-axis direction when being formed, totality of the core strueture 1 ' in the x-axis direction
Length is at least not less than the sum of principal length M1 and the length M2 of top edge sealing 2 ' of core strueture 1 ', i.e. M1+M2≤M0；Its
In, core strueture 1 ' allows the maximum length i.e. numerical value M0 used in the direction of the x axis.
And in the technical solution of the disclosure, it is proposed that for the improvement of core strueture.Fig. 3 is according to an exemplary implementation
A kind of schematic diagram of the core strueture exemplified, as shown in Figure 3：The core strueture 1 of the disclosure is carried out using mode shown in FIG. 1

Portion's edge sealing 2 is also comprising a bending part 23, and the bending part 23 is so that the direction of the head end 22 of top edge sealing 2 is different from the court of end 21
To that is, head end 22 is not set along the x-axis direction.
When the head end 22 of top edge sealing 2 is not set along the x-axis direction, i.e. the extending direction of head end 22 favours x-axis side
To so that in the case where the length of top edge sealing 2 is still M2 ', the length M2 of the top edge sealing 2 in the direction of the x axis is necessarily small
In M2 ', such as when head end 22 is when extending perpendicularly to x-axis or being further partial to top surface 11, top edge sealing 2 is in x-axis side
Upward length is minimum, only the spacing between end 21 and bending part 23.
Therefore, the principal length when core strueture 1 in the direction of the x axis is M1, the length of top edge sealing 2 in the direction of the x axis
For M2 when, if core strueture 1 is whole allow the maximum length used in the direction of the x axis still for M0 in the case of, it is known that：M1’≤
M0-M2’≤M1≤M0-M2.And in the case where other specifications of core strueture 1 are constant, it is clear that core strueture 1 can accommodate more
