Description
技术领域technical field
本发明涉及电池领域，尤其涉及一种锌氧化银电池组。The invention relates to the battery field, in particular to a zinc-silver oxide battery pack.
背景技术Background technique
当前锌氧化银电池组的结构如图1所示，均采用多个结构相同的单体电池外部串联组成。每个单体如图2所示，均具有一套独立的正极11、负极12、隔膜13、电解液14、壳体15。为达到一定的工作电压要求，现有的锌氧化银电池组要将多个单体串联，因此需要用到外部连接耳片16、极柱(正极柱17和负极柱18)、紧固螺母(图中未显示)等附属结构。The structure of the current zinc-silver oxide battery pack is shown in Figure 1, which are composed of multiple single cells with the same structure connected in series externally. As shown in FIG. 2 , each monomer has a set of independent positive electrode 11 , negative electrode 12 , separator 13 , electrolyte 14 , and casing 15 . In order to achieve a certain working voltage requirement, the existing zinc-silver oxide battery pack needs to connect multiple monomers in series, so it is necessary to use external connection tabs 16, poles (positive pole 17 and negative pole 18), fastening nuts ( not shown in the figure) and other auxiliary structures.
当前锌氧化银电池组的结构复杂，锌氧化银电池组的结构件在整个锌氧化银电池组中所占比例很大，导致锌氧化银电池组的比功率和比容量低，难以满足安装空间狭小，但工作电压、功率较高的使用要求。此外也对锌氧化银电池组的生产成本、安装工艺造成了不利影响。并且，因为每个单体电流由电极表面流经极柱过程中，电流流通的横截面积会变小，电流密度增大，易发生集耳效应，导致锌氧化银电池组的可靠性较低。The structure of the current silver-zinc oxide battery pack is complex, and the structural parts of the silver-zinc oxide battery pack account for a large proportion of the entire silver-zinc oxide battery pack, resulting in low specific power and specific capacity of the silver-zinc oxide battery pack, making it difficult to meet the installation space Narrow, but high working voltage and power requirements. In addition, it also adversely affects the production cost and installation process of the zinc-silver oxide battery pack. Moreover, because the current of each monomer flows from the electrode surface to the pole, the cross-sectional area of the current flow will become smaller, the current density will increase, and the ear effect will easily occur, resulting in lower reliability of the zinc-silver oxide battery pack. .
发明内容Contents of the invention

具体实施方式Detailed ways
为了使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明作进一步地详细描述，显然，所描述的实施例仅仅是本发明一部份实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
下面结合图3和图4对本发明实施例提供的锌氧化银电池组进行详细说明。The zinc-silver oxide battery pack provided by the embodiment of the present invention will be described in detail below with reference to FIG. 3 and FIG. 4 .
如图3所示，其为本发明实施例提供的锌氧化银电池组的结构示意图。As shown in FIG. 3 , it is a schematic structural diagram of a zinc-silver oxide battery pack provided by an embodiment of the present invention.
该锌氧化银电池组包括：壳体21、电解液22和多个电堆单元23构成的电堆24。电堆单元23包括：正极片25，负极片26，导电板27及隔膜28。The zinc-silver oxide battery pack includes: a casing 21 , an electrolyte solution 22 and a stack 24 composed of a plurality of stack units 23 . The stack unit 23 includes: a positive electrode sheet 25 , a negative electrode sheet 26 , a conductive plate 27 and a diaphragm 28 .
其中，正极片的活性物质为AgO粉，所述负极片的活性物质为Zn粉，隔膜为化纤与植物纤维纸，电解液为30～40％的氢氧化钾溶液Wherein, the active material of the positive plate is AgO powder, the active material of the negative plate is Zn powder, the separator is chemical fiber and plant fiber paper, and the electrolyte is 30-40% potassium hydroxide solution
该锌氧化银电池组不存在独立的单体，所有电池的正负极组件(电堆)、隔膜电解液均集中安装在一个壳体内，大大减少了现有锌氧化银电池组壳体结构，同时不存在现有锌氧化银电池组所需要的外部连接耳片、极柱、紧固螺母等附属结构，结构简单。The zinc-silver oxide battery pack does not have independent monomers, and the positive and negative electrode components (stacks) and diaphragm electrolytes of all batteries are collectively installed in one casing, which greatly reduces the shell structure of the existing zinc-silver oxide battery pack. At the same time, there are no external connection ear pieces, poles, fastening nuts and other auxiliary structures required by the existing zinc-silver oxide battery pack, and the structure is simple.
进一步的，每个电堆单元23的导电板27固定于壳体21的内侧，多个电堆单元23之间具有流通电解液22的空隙，以避免出现电解液不均匀的现象，从而降低了注液或者激活装置(贮备式新锌化银电池)的设计难度，并且在电解液注入后会形成自平衡，电堆24内部受力均匀，工作过程中，内部压力变化均匀。Further, the conductive plate 27 of each stack unit 23 is fixed on the inner side of the housing 21, and there are gaps between the plurality of stack units 23 to circulate the electrolyte 22, so as to avoid uneven electrolyte, thereby reducing the The design of the liquid injection or activation device (the storage type new silver zinc battery) is difficult, and self-balancing will be formed after the electrolyte is injected, the internal force of the stack 24 is uniform, and the internal pressure changes uniformly during the working process.
进一步的，电堆单元23的结构如图4所示，其为本发明实施例提供的锌氧化银电池组的电堆单元的结构示意图。Further, the structure of the stack unit 23 is shown in FIG. 4 , which is a schematic structural view of the stack unit of the zinc-silver oxide battery pack provided by the embodiment of the present invention.
正极片25与负极片26分别设置于导电板27的两侧，隔膜28包裹于正极片25及负极片26的外侧，以将多个电堆单元23隔离。The positive electrode sheet 25 and the negative electrode sheet 26 are respectively disposed on two sides of the conductive plate 27 , and the diaphragm 28 is wrapped on the outer side of the positive electrode sheet 25 and the negative electrode sheet 26 to isolate the stack units 23 .
电堆中除与电池组负极相连的电堆单元和与电池组正极相连的电堆单元外，每个电堆单元的负极片和与其相邻电堆单元的正极片相邻。Except for the stack unit connected to the negative pole of the battery pack and the stack unit connected to the positive pole of the battery pack in the stack, the negative electrode sheet of each stack unit is adjacent to the positive electrode sheet of its adjacent stack unit.
每个电堆单元的正极片和负极片表面均覆盖有隔膜，且相邻两个电堆单元的正极片和负极片被隔膜可靠分离，不能有任何直接接触的部分。The surface of the positive and negative electrodes of each stack unit is covered with a diaphragm, and the positive and negative electrodes of two adjacent stack units are reliably separated by the diaphragm without any direct contact.
由于该锌氧化银电池组通过导电板27将多个电堆单元23串联形成电堆24，因此电流流通的横截面积不会发生变化，电流密度不会发生变化，可有效避免集耳效应，从而提高锌氧化银电池组的可靠性。Since the zinc-silver oxide battery pack connects a plurality of stack units 23 in series to form a stack 24 through the conductive plate 27, the cross-sectional area of the current flow will not change, and the current density will not change, which can effectively avoid the ear effect. Thereby improving the reliability of the zinc-silver oxide battery pack.
通过本发明实施例提供的锌氧化银电池组，该锌氧化银电池组包括：壳体、电解液和多个电堆单元串联构成的电堆。因此该锌氧化银电池组不需要外部连接耳片、极柱、紧固螺母等附属结构，使得电池组的体积得以很大程度地压缩、重量得以很多程度地减轻。该锌氧化银电池组结构简，可提高锌氧化银电池组的比功率和比容量低，及对狭小安装空间的适应性。同时可降低锌氧化银电池组的生产成本、制造装配工艺难度。还可有效避免集耳效应，从而提高锌氧化银电池组的可靠性。The zinc-silver oxide battery pack provided by the embodiment of the present invention includes: a housing, an electrolyte solution, and a stack composed of a plurality of stack units connected in series. Therefore, the silver zinc oxide battery pack does not need external connection tabs, poles, fastening nuts and other auxiliary structures, so that the volume of the battery pack can be greatly compressed and the weight can be greatly reduced. The zinc-silver oxide battery pack has a simple structure, can improve the specific power and low specific capacity of the zinc-silver oxide battery pack, and can adapt to narrow installation spaces. At the same time, the production cost of the zinc-silver oxide battery pack and the difficulty of manufacturing and assembling processes can be reduced. It can also effectively avoid the ear effect, thereby improving the reliability of the zinc-silver oxide battery pack.
