Description

Technical Field

[0001] The present invention relates to a non-aqueous electrolyte battery.

Background Art

[0002] In recent years, in order to enable many people to access affordable, reliable, sustainable, and advanced energy, research and development of secondary batteries that contribute to energy efficiency have been carried out.

[0003] A secondary battery includes, for example, an electrode laminate in which a plurality of positive electrodes and a plurality of negative electrodes are laminated via an electrolyte, and a packaging material that houses the electrode laminate, and has a positive electrode tab lead and a negative electrode tab lead that protrude from the packaging material. A positive electrode tab converging portion 13a formed by converging positive electrode tabs extending from a plurality of positive electrodes is connected to the positive electrode tab lead, and a negative electrode tab converging portion 16a formed by converging negative electrode tabs extending from a plurality of negative electrodes is connected to the negative electrode tab lead.

[0004] Here, the positive electrode tab lead and the negative electrode tab lead are generally disposed substantially at the center with respect to the thickness in the stacking direction of the electrode laminate. For this reason, the length of the tab from the electrode plate to the tab lead is different for each electrode plate.

[0005] FIG. 5 is a cross-sectional view showing the configuration of a conventional non-aqueous electrolyte battery according to an embodiment. The non-aqueous electrolyte battery 10 shown in FIG. 5 includes an electrode laminate 11, a packaging material 12 that houses the electrode laminate 11, a positive electrode tab lead 14 and a negative electrode tab lead 17 that protrude from the packaging material 12. A positive electrode tab converging portion 13a formed by converging positive electrode tabs 13 extending from a plurality of positive electrodes is connected to the positive electrode tab lead 14, and a negative electrode tab converging portion 16a formed by converging negative electrode tabs 16 extending from a plurality of negative electrodes is connected to the negative electrode tab lead 17.

[0006] In the non-aqueous electrolyte battery 10 shown in FIG. 5, the positive electrode tab lead 14 and the negative electrode tab lead 17 protruding from the packaging material 12 are arranged to protrude in opposite directions at both ends in the stacking direction of the electrode laminate 11. A plurality of positive electrodes are connected to the positive electrode tab lead 14 via a plurality of positive electrode tabs 13, and a plurality of negative electrodes are connected to the negative electrode tab lead 17 via a plurality of negative electrode tabs 16.

[0007] Here, the non-aqueous electrolyte battery expands and contracts with charge and discharge, and the thickness of the electrode laminate increases upon charging. When the thickness of the electrode laminate increases, the tensions of the respective tabs constituting the non-aqueous electrolyte battery become different.

[0008] Specifically, the tabs extending from near the uppermost surface and the lowermost surface of the laminate are subjected to a greater tension compared to the tabs extending from near the central portion when the electrode laminate expands in volume. For this reason, the tabs extending from near the uppermost surface and the lowermost surface of the laminate were at risk of breakage (foil break). In particular, in the case of a battery with a large expansion amount or a hard battery, the tension applied to the tabs tends to increase. Further, even if the tabs do not break (foil break), damage may be imparted to the electrode plate near the tabs, leading to a short circuit or performance degradation of the non-aqueous electrolyte battery.

[0009] On the other hand, in Patent Document 1, for the purpose of suppressing non-uniformity in the expansion amount of an all-solid-state battery having a lithium metal negative electrode, it is proposed to make the "difference between the maximum value and the minimum value of the electrical resistance from the electrode to the gathering portion" of each tab equal to or less than a threshold value. As a method of making the resistance difference equal to or less than the threshold value, it is described that each tab is formed of the same material and the lengths are made uniform.

[0010] However, the method described in Patent Document 1 suppresses breakage of the tabs due to the force in the tensile direction by bending the tabs in order to make the lengths of the tabs uniform and suppress non-uniformity in the expansion amount of the battery. Therefore, it does not control the tension of each tab itself.

The non-aqueous electrolyte battery of the present disclosure has a positive electrode tab lead and a negative electrode tab lead protruding from the packaging material.

[0019] In the non-aqueous electrolyte battery of the present disclosure, a positive electrode tab extends from the positive electrode, the ends of the plurality of positive electrode tabs converge to form a positive electrode tab converging portion, and the positive electrode tab converging portion is connected to the positive electrode tab lead.

[0020] Furthermore, in the non-aqueous electrolyte battery of the present disclosure, a tab fixing material is disposed between at least one of adjacent negative electrode tabs and / or between at least one of adjacent positive electrode tabs. By disposing the tab fixing material between the negative electrode tabs and / or between the positive electrode tabs, it is possible to suppress an increase in the tension between the disposed negative electrode tab bundle portion and / or positive electrode tab bundle portion and the tab fixing material. As a result, the tension applied to the portion where the tabs of each tab converge can be kept equal, and breakage of the tabs during volume expansion of the electrode laminate can be suppressed.

[0021] [Type of non-aqueous electrolyte battery] The type of the non-aqueous electrolyte battery of the present disclosure is not particularly limited. The non-aqueous electrolyte battery of the present disclosure may be, for example, a solid battery cell such as an all-solid-state lithium ion battery cell or an all-solid-state lithium metal battery cell, or a non-aqueous electrolyte battery cell such as a lithium metal battery cell. Among these, solid battery cells are preferred.

[0022] [Packaging material] In the non-aqueous electrolyte battery of the present disclosure, a packaging material known in the field of non-aqueous electrolyte batteries can be applied as the packaging material. Examples of such a packaging material include a metal and a film having a resin layer formed on the surface of a metal layer. Examples of the metal constituting the metal layer include aluminum. Examples of the resin constituting the resin layer include polyethylene, polyvinyl fluoride, and polyvinylidene chloride.

[0023] [Electrode laminate] In the non-aqueous electrolyte battery of the present disclosure, the electrode laminate is a laminate in which a plurality of positive electrodes and a plurality of negative electrodes are laminated via an electrolyte, and is housed in a packaging material.

[0024] (Positive electrode) In the non-aqueous electrolyte battery of the present disclosure, the positive electrode constituting the electrode laminate is not particularly limited, and a positive electrode known in non-aqueous electrolyte batteries can be used. For example, when the non-aqueous electrolyte battery of the present disclosure is an all-solid-state lithium metal battery, the positive electrode has a laminated structure of a positive electrode current collector and a positive electrode mixture layer, and the positive electrode mixture layer is disposed so as to be adjacent to the electrolyte layer.

[0025] When the non-aqueous electrolyte battery of the present disclosure is an all-solid-state lithium metal battery, the positive electrode current collector is not particularly limited, and examples thereof include aluminum foil. Further, the positive electrode composite layer contains a positive electrode active material as an essential component and may optionally contain a solid electrolyte, a conductive assistant, a binder, and the like.

[0026] The positive electrode active material is not particularly limited as long as it can occlude and release lithium ions. Examples of the positive electrode active material include, for example, LiCoO2, Li(Ni 5 / 10 Co 2 / 10 Mn 3 / 10 )O 2、 Li(Ni 6 / 10 Co 2 / 10 Mn 2 / 10 )O 2、 Li(Ni 8 / 10 Co 1 / 10 Mn 1 / 10 )O 2、 Li(Ni 0.8 Co 0.15 Al 0.05 )O 2、 Li(Ni 1 / 6 Co 4 / 6 Mn 1 / 6 )O 2、 Li(Ni 1 / 3 Co 1 / 3 Mn 1 / 3 )O 2、 LiCoO4, LiMn2O4, LiNiO2, LiFePO4, lithium sulfide, sulfur.

[0027] (Negative electrode) In the non-aqueous electrolyte battery of the present disclosure, the negative electrode constituting the electrode laminate is not particularly limited, and a negative electrode known in non-aqueous electrolyte batteries can be used. For example, when the non-aqueous electrolyte battery of the present disclosure is an all-solid-state lithium metal battery, the negative electrode has a laminated structure of a lithium metal layer and a negative electrode current collector, and the lithium metal layer is arranged so as to be adjacent to the electrolyte layer. Alternatively, an intermediate layer for equalizing the dissolution and precipitation of lithium may be arranged between the lithium metal layer and the electrolyte layer.

[0028] When the non-aqueous electrolyte battery of the present disclosure is an all-solid-state lithium metal battery, the negative electrode current collector is not particularly limited, and examples thereof include a copper foil.

[0029] (Electrolyte) In the non-aqueous electrolyte battery of the present disclosure, the electrolyte constituting the electrode laminate is not particularly limited, and an electrolyte known in non-aqueous electrolyte batteries can be used. Examples of the electrolyte include an electrolytic solution and a solid electrolyte. When an electrolytic solution is used, the electrolytic solution is held and disposed in the separator. For example, when the non-aqueous electrolyte battery of the present disclosure is an all-solid-state lithium metal battery, the electrolyte disposed between the positive electrode and the negative electrode is disposed between the positive electrode composite layer and the lithium metal layer.

[0030] When the non-aqueous electrolyte battery of the present disclosure is an all-solid-state lithium metal battery, the electrolyte becomes a solid electrolyte layer. The solid electrolyte constituting the solid electrolyte layer is not particularly limited as long as it is a material capable of conducting lithium ions. Examples of the solid electrolyte include an oxide-based electrolyte and a sulfide-based electrolyte.

[0031] [Positive electrode tab lead, negative electrode tab lead] In the non-aqueous electrolyte battery of the present disclosure, a positive electrode tab lead and a negative electrode tab lead protrude from the packaging material.

[0032] (Arrangement of positive electrode tab lead and negative electrode tab lead) In the non-aqueous electrolyte battery of the present disclosure, the protruding directions of the positive electrode tab lead and the negative electrode tab lead protruding from the packaging material are not particularly limited. The protruding directions of the positive electrode tab lead and the negative electrode tab lead may be in opposite directions, the same direction, or an oblique direction. It can be appropriately selected according to the usage environment of the non-aqueous electrolyte battery of the present disclosure and the configuration of the module formed from a plurality of non-aqueous electrolyte batteries.

[0033] (Number of positive electrode tab leads and negative electrode tab leads) The non-aqueous electrolyte battery of the present disclosure may be a single battery in which a positive electrode tab lead and a negative electrode tab lead are respectively connected to all the positive electrodes and negative electrodes constituting the electrode laminate, or a laminate unit in which a positive electrode, an electrolyte, and a negative electrode are laminated is divided into several sub-stacks, and for each sub-stack, it may be a battery pack in which a positive electrode tab lead and a negative electrode tab lead are connected. When the non-aqueous electrolyte battery of the present disclosure is a single battery, the number of the positive electrode tab lead and the negative electrode tab lead is one each. When the non-aqueous electrolyte battery of the present disclosure is a battery pack, the number of the positive electrode tab lead and the negative electrode tab lead is a plurality each.

[0034] [Tab fixing material] In the non-aqueous electrolyte battery of the present disclosure, a tab fixing material is disposed between at least one of adjacent negative electrode tabs and / or at least one of adjacent positive electrode tabs. The tab fixing material functions to suppress the movement of the tab, and with the tab fixing material as the center, the tab can be divided into a portion where tension is applied during volume expansion of the electrode laminate and a portion where the tabs converge (connection portion with the tab lead). By suppressing the movement of the tab by the tab fixing material, even when the electrode laminate expands in volume, it is possible to suppress an increase in tension caused by the portion where the tabs of each tab converge (connection portion with the tab lead) being pulled, so that the tension of each tab can be kept equal and breakage of the tab can be suppressed.

[0035] FIG. 1 is a cross-sectional view of an end portion on the negative electrode tab lead 4 side of the non-aqueous electrolyte battery 1 according to an embodiment of the present invention. The non-aqueous electrolyte battery 1 shown in FIG. 1 is a battery in which an electrode laminate (not shown) is housed in a packaging material 2, and a tab fixing material 5 is disposed between all adjacent negative electrode tabs 3. In the non-aqueous electrolyte battery 1, the tab fixing material 5 is disposed between a positive electrode tab converging portion 3a connected to the negative electrode tab lead 4 and an electrode laminate (not shown).

[0036] (Shape of tab fixing material) In the non-aqueous electrolyte battery 1 shown in FIG. 1, the tab fixing member 5, which is a plurality of individual members, each has a substantially rectangular parallelepiped shape, but is not particularly limited as long as it can suppress the movement of the tab. As will be described later, the surface of the tab fixing member that faces the tab and contacts the tab may be a curved surface. Also, for example, it may be a single member having a length equivalent to the length in the thickness direction of the electrode laminate, or a plurality of individual members respectively arranged between adjacent tabs. In the case of a single member, for example, it may have a plurality of recesses, and the tabs may be arranged so that each tab passes through the recesses, and the tab fixing member may be sandwiched between the packaging materials on the upper and lower surfaces in the thickness direction of the electrode laminate, whereby the tab fixing member can be fixed within the packaging material.

[0037] In the non-aqueous electrolyte battery 1 shown in FIG. 1, the tab fixing member 5 is a plurality of individual members, and each individual tab fixing member 5 is arranged between adjacent negative electrode tabs.

[0038] (Arrangement location of tab fixing member) The arrangement location of the tab fixing member may be at least one between adjacent negative electrode tabs and / or at least one between adjacent positive electrode tabs, and is not particularly limited. By arranging it near the part where the tabs converge (connection part with the tab lead), the length of the tab can be shortened and the battery can be miniaturized, so that it can contribute to the energy density of the obtained non-aqueous electrolyte battery.

[0039] Generally, in a non-aqueous electrolyte battery, the expansion of the negative electrode is larger than that of the positive electrode. Therefore, by arranging the tab fixing member at least between the negative electrode tabs, the effects of the present invention can be more enjoyed.

[0040] In addition, when a plurality of individual tab fixing members are respectively arranged between adjacent tabs, the tab fixing members may be arranged such that the distance from the portion where the tabs converge (the connection portion with the tab lead) to the tab fixing members is constant. If a plurality of tab fixing members are arranged such that the distance from the portion where the tabs converge (the connection portion with the tab lead) to the tab fixing members is constant, the battery can be made smaller and contribute to the energy density of the resulting battery.

[0041] (Material of tab fixing member) The material of the tab fixing member is not particularly limited. It may be an insulator or a conductor, but it is preferably an insulator. When the tab fixing member is formed of an insulator, in the lamination process of the electrode laminate (the process before tab convergence), reflux between laminations during abnormal times can be prevented, and it becomes easier to ensure process safety.

[0042] (Method of arranging tab fixing member) The method of arranging the tab fixing member on the negative tab and / or the positive tab is not particularly limited as long as the tab fixing member can be arranged. Examples of the method of arranging the tab fixing member on the negative tab and / or the positive tab include welding or soldering to the tab, or friction fixing to the tab. Among them, friction fixing is preferably used. If it is friction fixing, the tab fixing member can be fixed to the tab only by the load during tab convergence by controlling the friction coefficient of the tab fixing member.

[0043] Note that the tab fixing member may be arranged simultaneously when applying the positive electrode composite material or the like to the current collector, or may be arranged in any subsequent process.

[0044] (Contact surface of tab fixing member with tab) The contact surface of the tab fixing member with the tab, that is, the surface substantially perpendicular to the lamination direction of the electrode laminate and facing the tab, is not particularly limited. The contact surface of the tab fixing member with the tab may be, for example, a flat surface, a curved surface, or a stepped surface having a step.

[0045] Among them, the contact surface of the tab fixing member with the tab, that is, the surface that faces the tab and contacts the tab, is preferably a curved surface. By making the surface of the tab fixing member facing the tab a curved surface, the contact area between the tab and the tab fixing member increases, the frictional force increases, and the fixing force for fixing the tab can be increased.

[0046] When the contact surface of the tab fixing member with the tab is a curved surface, even if the entire tab fixing member has a gentle curve, or the corners of the tab fixing member are chamfered to have an R shape, it is also acceptable. When the entire tab fixing member has a gentle curve, for example, the cross-sectional shape of the tab fixing member may be an elliptical shape.

[0047] As described above, the embodiments of the present invention have been described. However, the present invention is not limited to the above embodiments, and the above embodiments may be appropriately modified within the scope of the gist of the present invention.

[0048] For example, FIGS. 2 to 4 are cross-sectional views of the negative electrode tab lead side end portion of the non-aqueous electrolyte battery according to a modified example of the above embodiment. In the modified example shown in FIG. 2, tab fixing members 5a and 5b are arranged side by side in the plane direction of the electrode laminate 11 as the tab fixing member 5. In this way, a configuration in which a plurality of tab fixing members are arranged side by side in the plane direction of the electrode laminate may be provided between at least one of the tabs.

[0049] In the modified example shown in FIG. 3, the tab fixing member 5 is arranged between the negative electrode tabs 3 at both ends of the electrode laminate 11 in the stacking direction. In this way, a configuration in which it is arranged between the negative electrode tabs and / or between the positive electrode tabs at both ends of the electrode laminate in the stacking direction may be provided.

[0050] In the modified example shown in FIG. 4, in addition to between all the negative electrode tabs 3, the tab fixing member 5 is also arranged between the negative electrode tab 3 and the packaging material 2 at both ends of the electrode laminate 11 in the stacking direction. In this way, a configuration in which the tab fixing member is further arranged at least on one side between the negative electrode tab and the packaging material and / or at least on one side between the positive electrode tab and the packaging material at both ends of the electrode laminate in the stacking direction may be provided.
