背景技术Background technique

固态电池是一种电池科技。与现今普遍使用的锂离子电池和锂离子聚合物电池不同的是，固态电池是一种使用固体电极和固体电解质的电池。传统的液态锂电池又被科学家们形象地称为“摇椅式电池”，摇椅的两端为电池的正负两极，中间为电解质(液态)。而锂离子就像优秀的运动员，在摇椅的两端来回奔跑，在锂离子从第一电容电极到第二电容电极再到第一电容电极的运动过程中，电池的充放电过程便完成了。固态电池的原理与之相同，只不过其电解质为固态，具有的密度以及结构可以让更多带电离子聚集在一端，传导更大的电流，进而提升电池容量。因此，同样的电量，固态电池体积将变得更小。不仅如此，固态电池中由于没有电解液，封存将会变得更加容易，在汽车等大型设备上使用时，也不需要再额外增加冷却管、电子控件等，不仅节约了成本，还能有效减轻重量。Solid-state battery is a battery technology. Unlike lithium-ion batteries and lithium-ion polymer batteries commonly used today, solid-state batteries are batteries that use solid electrodes and solid electrolytes. The traditional liquid lithium battery is vividly called "rocking chair battery" by scientists. The two ends of the rocking chair are the positive and negative poles of the battery, and the middle is the electrolyte (liquid). Lithium ions are like excellent athletes, running back and forth on both ends of the rocking chair. During the movement of lithium ions from the first capacitor electrode to the second capacitor electrode and then to the first capacitor electrode, the charging and discharging process of the battery is completed. The principle of a solid-state battery is the same, except that its electrolyte is solid, with a density and structure that allows more charged ions to gather at one end, conduct more current, and thereby increase battery capacity. Therefore, with the same amount of power, the volume of solid-state batteries will become smaller. Not only that, because there is no electrolyte in the solid-state battery, it will be easier to seal it. When used in large equipment such as automobiles, there is no need to add additional cooling tubes, electronic controls, etc., which not only saves costs, but also effectively reduces weight.

现有的固态电池虽然在一定程度上能够满足使用要求，但是仍存在以下不足：Although the existing solid-state batteries can meet the usage requirements to a certain extent, they still have the following shortcomings:

1)固态离子导体与电极之间的结合力不足；1) The bonding force between the solid ion conductor and the electrode is insufficient;

2)固态离子导体与电极之间的亲润性较差；2) The wettability between the solid ion conductor and the electrode is poor;

3)固态离子导体与电极之间的界面电阻较大。3) The interface resistance between the solid ion conductor and the electrode is relatively large.

发明内容Summary of the invention

有鉴于此，本发明的目的在于提供一种全固态储能设备复合电极材料、电芯、叠层电芯、复合电芯和复合动力电芯，能够有效增强固态离子导体与电极之间的结合力以及亲润性，并能够有效减小固态离子导体与电极之间的界面电阻，提高离子渗透率。In view of this, the purpose of the present invention is to provide a composite electrode material, cell, laminated cell, composite cell and composite power cell for all solid-state energy storage devices, which can effectively enhance the combination between solid ion conductor and electrode Strength and wettability, and can effectively reduce the interface resistance between the solid ion conductor and the electrode, and improve the ion permeability.

具体的，本实施例的全固态储能设备叠层电芯的结构具有多种变化：Specifically, the structure of the all-solid-state energy storage device laminated cell of this embodiment has various changes:

如图24和25所示，为采用实施例3中的全固态储能设备电芯100组合为全固态储能设备叠层电芯时的结构示意图，该全固态储能设备叠层电芯中，全固态储能设备电芯100的数量可以为2个、3个及3个以上，且相邻两个全固态储能设备电芯100中，其中一个全固态储能设备电芯100端部的第一电极10与另一个全固态储能设备电芯100端部的第二电极20相邻设置，且在该相邻的第一电极10和第二电极20之间设有电子导电但离子隔离的双极集流板102。As shown in Figures 24 and 25, it is a schematic diagram of the structure when the all-solid-state energy storage device cell 100 in Embodiment 3 is combined into an all-solid-state energy storage device laminated cell. , The number of all-solid-state energy storage device cells 100 can be 2, 3, or more than 3, and among the two adjacent all-solid-state energy storage device cells 100, one of the all-solid-state energy storage device cell 100 ends The first electrode 10 is arranged adjacent to the second electrode 20 at the end of another all-solid-state energy storage device cell 100, and between the adjacent first electrode 10 and the second electrode 20, there is an electronic conductive but ionic Isolated bipolar current collecting plate 102.

以此类推，当全固态储能设备电芯100中的第一电极10的数量N与第二电极20的数量M满足M＝N≥1时，此时仅需将所有的全固态储能设备电芯100依次层叠在一起即可，在相邻两个全固态储能设备电芯100中，其中一个全固态储能设备电芯100端部的第一电极10与另一个全固态储能设备电芯100端部的第二电极20相邻设置，并在该相邻的第一电极10和第二电极20之间设有电子导电但离子隔离的双极集流板102。By analogy, when the number N of the first electrodes 10 and the number M of the second electrodes 20 in the all-solid-state energy storage device cell 100 satisfy M=N≥1, then only all the all-solid-state energy storage devices The battery cells 100 can be stacked in sequence. Among the two adjacent all-solid-state energy storage device batteries 100, the first electrode 10 at the end of one all-solid-state energy storage device battery cell 100 and the other all-solid-state energy storage device The second electrode 20 at the end of the cell 100 is arranged adjacently, and an electronically conductive but ion-isolated bipolar current collector 102 is provided between the adjacent first electrode 10 and the second electrode 20.

In the all-solid-state energy storage device laminated cell, in order to realize the two adjacent all-solid-state energy storage device cells 100, the first electrode 10 at the end of one all-solid-state energy storage device cell 100 and the other all In the structure where the second electrode 20 at the end of the solid-state energy storage device cell 100 is arranged adjacently, the all-solid-state energy storage device cell 100 in Embodiment 4 needs to be interleaved with the all-solid-state energy storage device cell 100 in Embodiment 5 Stacked together, in this way, in two adjacent all-solid-state energy storage device cells 100, the first electrode 10 at the end of one all-solid-state energy storage device cell 100 and the other all-solid-state energy storage device cell The second electrode 20 at the end of 100 is arranged adjacently, and an electronically conductive but ion-isolated bipolar current collector 102 is provided between the adjacent first electrode 10 and the second electrode 20.

以此类推，当全固态储能设备电芯100中的第一电极10的数量N与第二电极20的数量M满足|M-N|＝1，且第一电极的数量N≥1，第二电极的数量M≥1时，此时的相邻两个全固态储能设备电芯100中，其中一个全固态储能设备电芯100的第一电极数量N与第二电极数量M之间满足N-M＝1，另一个全固态储能设备电芯100的第一电极数量N与第二电极数量M之间满足M-N＝1，以确保该相邻两个全固态储能设备电芯100中，其中一个全固态储能设备电芯100端部的第一电极10与另一个全固态储能设备电芯100端部的第二电极20相邻设置，并在该相邻的第一电极10和第二电极20之间设有电子导电但离子隔离的双极集流板102。By analogy, when the number N of first electrodes 10 and the number M of second electrodes 20 in the all-solid-state energy storage device cell 100 satisfy |MN|=1, and the number of first electrodes N≥1, the second electrode When the number M≥1, in the two adjacent all-solid-state energy storage device cells 100 at this time, one of the all-solid-state energy storage device cells 100 has a first electrode number N and a second electrode number M that satisfy NM =1, the first electrode number N and the second electrode number M of another all-solid-state energy storage device cell 100 satisfy MN=1 to ensure that the two adjacent all-solid-state energy storage device cells 100 are The first electrode 10 at the end of one all-solid-state energy storage device cell 100 and the second electrode 20 at the end of the other all-solid-state energy storage device cell 100 are arranged adjacent to each other. A bipolar current collecting plate 102 is provided between the two electrodes 20, which is electrically conductive but ion-isolated.

当然，当全固态储能设备电芯100中的第一电极10的数量N与第二电极20的数量M满足|M-N|＝1且第一电极的数量N≥1，第二电极的数量M≥1时，此时包括两类结构的全固态储能设备电芯100中，其中一类全固态储能设备电芯100的第一电极数量N与第二电极数量M之间满足N-M＝1，另一类全固态储能设备电芯100的第一电极数量N与第二电极数量M之间满足M-N＝1，在该两类全固态储能设备电芯100之间，还可以层叠至少一个第一电极数量N与第二电极数量M之间满足N＝M的全固态储能设备电芯100，仅需保证相邻两个全固态储能设备电芯100中，其中一个全固态储能设备电芯100端部的第一电极10与另一个全固态储能设备电芯100端部的第二电极20相邻设置，并在该相邻的第一电极10和第二电极20之间设有电子导电但离子隔离的双极集流板102即可，不再累述。Of course, when the number N of first electrodes 10 and the number M of second electrodes 20 in the all-solid-state energy storage device cell 100 satisfy |MN|=1 and the number of first electrodes N≥1, the number of second electrodes M When ≥1, at this time, there are two types of all-solid-state energy storage device cells 100, where the number of first electrodes N and the number of second electrodes M of the all-solid-state energy storage device cells 100 satisfy NM=1 , The first electrode number N and the second electrode number M of another type of all-solid-state energy storage device cell 100 satisfy MN=1. Between the two types of all-solid-state energy storage device cells 100, at least For an all-solid-state energy storage device cell 100 that satisfies N=M between the number of first electrodes N and the number of second electrodes M, it is only necessary to ensure that of the two adjacent all-solid-state energy storage device cells 100, one of them The first electrode 10 at the end of the energy device cell 100 is adjacent to the second electrode 20 at the end of the other all-solid-state energy storage device cell 100, and is located between the adjacent first electrode 10 and the second electrode 20 It is only necessary to provide a bipolar current collecting plate 102 that is electrically conductive but isolated from ions, which will not be repeated here.
