Fig. 1 is a schematic cross-sectional view of a battery cell 100 in the related art. As shown in fig. 1, the battery cell 100 may include a positive electrode tab 101, a negative electrode tab 102, and a diaphragm 103, where the diaphragm 103 is located between the positive electrode tab 101 and the negative electrode tab 102. The battery cell 100 may further include a positive tab 104 and a negative tab 105, where the positive tab 104 is connected to the winding head end of the positive tab 101, and the negative tab 105 is connected to the head end of the negative tab 102. It is assumed that the battery cell 100 is wound several times and then terminated at the lower surface shown in fig. 1, that is, the lower surface can be regarded as the terminating surface of the battery cell 100.

On the tail surface of the battery core 100, local areas are wound by the base material of the separator and the positive electrode plate 101, so that the tail surface is not flat, and thus the surface of the battery containing the battery core 100 corresponding to the tail surface is not flat. In the related art, in order to adapt to the existing wiring and circuit in the device and achieve generalization, the battery configured with the battery cell 100 is usually installed in the battery compartment of the configuration device in an arrangement manner of "right and left positive" in a direction perpendicular to the direction in which the ending surface extends toward the inside of the battery cell 100. Then, it can be understood that when the battery containing the battery core 100 is assembled into a battery compartment, the tail surface of the battery core 100 is disposed close to the bottom of the battery compartment, and due to the unevenness of the tail surface, the adhesive tape for bonding the battery and the battery compartment cannot be completely attached to the lower portion of the battery compartment, and the activation rate of the back adhesive is reduced.

In a related art, based on the winding structure in fig. 1, the base material of the positive electrode sheet 101 and the separator 103 are wound by half a turn clockwise, so that the end surface of the battery cell 100 is transferred to the upper surface in fig. 1, and the surface assembled with the battery compartment is flat. However, in this technical solution, since the base materials of the diaphragm 103 and the positive electrode tab 101 are wound by half a turn, the thicknesses of the base materials of the two layers of the diaphragm 103 and the one layer of the positive electrode tab 101 are increased, the capacity density of the battery cell 100 is sacrificed, and the electric quantity of the battery cell 100 is reduced under the same size.

In order to avoid increasing the thickness of the battery cell 100 while enhancing the activation rate of the back adhesive, in another related art, the battery cell 100 shown in fig. 1 is mounted upside down in a battery compartment, i.e., the opposite surface of the tail-closing surface is disposed close to the lower portion of the battery compartment. However, when the battery cell 100 is mounted upside down, the positions of the positive tab 104 and the negative tab 105 are changed to be in a left-negative-right-positive arrangement mode, and in order to adapt to a new positive and negative arrangement mode, the routing of the battery protection needs to be redesigned, the length of the flexible circuit board between the tabs and the battery protection board is extended, and the temperature rise of the battery is increased.

Therefore, based on the technical problems in the above technical solutions, the present disclosure provides a new cell structure. Fig. 2 is a schematic structural diagram of a wound battery cell 200 according to an exemplary embodiment. As shown in fig. 2, the winding-type cell 200 may include a positive tab 1, a negative tab 2, and a winding-trailing face 3, and in a direction extending perpendicular to the winding-trailing face 3 toward the inside of the winding-type cell 200, that is, in a direction indicated by an arrow a in fig. 2, assuming that the positive tab and the negative tab of the battery cell 100 in the related art and the winding-type cell 200 in the present disclosure are both located on the top and viewed at the same angle behind the battery cell 100 and the winding-type cell 200, it can be seen that in the related art, the negative tab 105 is located on the right side of the positive tab 104, and in the present disclosure, the negative tab 2 is located on the left side of the positive tab 1, that is, in a direction indicated by a key head a, the positive tab 1 and the negative tab 2 are arranged in a manner of "left negative right positive tab" and left ".

Further, the winding type battery cell 200 may further include a mounting surface 4, the mounting surface 4 is disposed opposite to the winding tail surface 3, and the mounting surface 4 is configured to be adapted to a bottom surface of a battery compartment for accommodating the winding type battery cell 200, that is, when the winding type battery cell 200 is mounted in the battery compartment, the winding type battery cell may be rotated 180 ° based on the embodiment shown in fig. 2, and then be assembled to the battery compartment downward in the manner shown in fig. 3, so that the mounting surface 4 is disposed close to the bottom of the battery compartment, and thus the arrangement manner of the positive electrode tab 1 and the negative electrode tab 2 is changed to "positive right and positive left negative" at this time, and adapted to the current general arrangement manner, which may avoid adjusting the routing of the battery protection board, and does not need to increase the length of the flexible printed circuit board, and since the flat mounting surface 4 is disposed towards the bottom surface of the battery compartment, it is beneficial to increase the gum activation rate of the battery, improve the bonding strength, and does not need to increase the thickness of the battery cell, without sacrificing the energy density of the cell.

In this embodiment, as also shown in fig. 2 and fig. 3, the wound electrical core 200 may further include a positive electrode sheet 5, a negative electrode sheet 6, and a separator 7, where the separator 7 is disposed between the positive electrode sheet 5 and the negative electrode sheet 6, the positive electrode sheet 5 may include a positive winding head 51, and the positive tab 1 is connected to the positive winding head 51; similarly, the negative electrode tab 6 may include a negative winding head 61, the negative electrode tab is connected to the negative winding head 61, and the positive winding head 51 and the negative winding head 61 are both located inside the winding type battery cell 200. The end of the negative electrode winding head 61 is located between the positive electrode tab 1 and the negative electrode tab 2, and the end of the positive electrode winding head 51 is located on the side of the positive electrode tab 1 away from the negative electrode winding head 61, that is, the positive electrode winding head 51 can extend towards the direction away from the negative electrode winding head 61, so that the spacing distance between the positive electrode winding head 51 and the negative electrode winding head 61 is increased, the probability of contact between the positive electrode winding head 51 and the negative electrode winding head 61 is reduced, and the safety performance of the winding type battery cell 200 is improved.

In an embodiment, as shown in fig. 4, the positive electrode sheet 5 may further include a first protective adhesive layer 52, the first protective adhesive layer 52, and the first protective adhesive layer 52 may be attached to a surface of the positive electrode winding head 51 facing the negative electrode winding head 61, so that the negative electrode winding head 61 may be protected by the first protective adhesive layer 52. Further, as shown in fig. 4, in the thickness direction of the wound battery cell 200, a part of the projection of the first protective adhesive layer 52 on the negative winding head 61 overlaps, that is, the first protective adhesive layer 52 extends toward the negative winding head 61 and exceeds the negative winding head 61, so that the negative winding head 61 is ensured to fall within the protection range of the first protective adhesive layer 52.

For example, the positive electrode plate 5 may further include a substrate and a positive active material coated on an opposite surface of the substrate. In some cases, the lengths of the positive electrode active materials applied to the two oppositely disposed surfaces may be different, and for example, the first protective adhesive layer 52 may be attached to a region corresponding to the positive electrode winding head 51 on the surface where the applied length of the positive electrode active material is long.

In another embodiment, as shown in fig. 5, the negative electrode tab 6 may further include a second protective adhesive layer 62, and the second protective adhesive layer 62 is attached to a surface of the negative electrode tab 6 closest to the corner region of the positive electrode winding head 51, and the surface is disposed toward the positive electrode winding head 51, so that the positive electrode winding head 51 may be prevented from contacting the negative electrode tab 6 on both sides of the positive electrode winding head 51, and a short circuit may be avoided.

Further, as shown in fig. 5, in the thickness direction of the wound electrical core 200, the projection of the second protective adhesive layer 62 coincides with a part of the projection of the positive electrode winding head 51, so that the end of the positive electrode winding head 51 falls within the protection range of the second protective adhesive layer 62, and when the wound electrical core 200 is impacted or impacted, the probability that the positive electrode winding head 51 contacts with the negative electrode tab 6 is reduced, which is beneficial to improving the safety performance of the battery including the wound electrical core 200.

For example, the negative electrode plate 6 may further include a substrate and a negative active material coated on an opposite surface of the substrate. In some cases, the lengths of the negative electrode active materials applied to the two oppositely disposed surfaces may be different, and for example, the second protective adhesive layer 62 may be attached to the surface disposed toward the positive electrode winding head 51 corresponding to the corner region on the surface having the shorter application length of the negative electrode active material.

Based on the technical scheme provided by the present disclosure, as shown in fig. 6, a processing process of a winding type battery cell is further provided, and the processing process may include the following steps:

The positive electrode active material is coated in the middle area of the positive electrode substrate, the negative electrode active material is coated in the middle area of the negative electrode substrate, the positive electrode substrate can comprise aluminum foil, the negative electrode substrate can be copper foil, and the diaphragm has insulating property.

When obtaining positive pole piece, can also be on positive pole coiling head the attached first protection glue film in surface that negative pole coiling head set up, in the coiling formula electricity core, this first protection glue film is located between anodal ear and the negative pole ear, and in the thickness direction of coiling formula electricity core, the projection of this first protection glue film is in the partly coincidence of the projection of negative pole coiling head to avoid negative pole coiling head to contact positive pole piece, this first protection glue film can include one or more, this disclosure is not limited to this.

Similarly, the position of the corner area, which is closest to the positive winding head, on the negative electrode pole piece can be determined, the second protective adhesive layer is attached to the surface, facing the positive winding head, of the negative electrode pole piece, and the positive winding head is protected by the second protective adhesive layer, so that the situation that the positive winding head is in contact with the negative electrode pole piece to cause short circuit is avoided. In the thickness direction of the winding type battery cell, the projection of the second protective adhesive layer is overlapped with a part of the projection of the positive electrode winding head, so that the positive electrode winding head is ensured to fall into the protection range of the second protective adhesive layer, and the short-circuit protection of the positive electrode winding head is ensured.

And step 604, finishing winding after the positive pole piece, the negative pole piece and the diaphragm are wound for at least one circle until a preset winding ending surface is reached, wherein the negative pole tab is positioned on the left side of the positive pole tab in a direction perpendicular to the direction in which the preset winding ending surface extends towards the interior of the winding type battery cell.

In this embodiment, after the positive electrode sheet, the negative electrode sheet, and the separator are wound several times, the winding may be finished on the preset winding end face, and at this time, the negative electrode tab is located on the left side of the positive electrode tab in a direction extending toward the inside of the wound electrical core perpendicular to the preset winding end face.
