一组卷绕极板定义为具有卷绕成螺旋形的一极板和隔板的成品。电池和电解电容器是卷绕极板组的典型例子。下面将描述卷绕极板组的一典型例子-电池。A set of wound plates is defined as a finished product having a plate and a separator wound in a helical shape. Batteries and electrolytic capacitors are typical examples of wound plate packs. A typical example of a wound plate group - a battery will be described below.

如今，随着各种便携式电子装置的广泛使用，例如摄像机、摄录一体机、便携式CDP、收音机、盒式磁带机、笔记本电脑、寻呼机和蜂窝式电话等，这些装置要求具有更高容量和更长寿命的电池。Today, with the widespread use of various portable electronic devices, such as video cameras, camcorders, portable CDPs, radios, cassette players, notebook computers, pagers, and cellular phones, these devices require higher capacity and more Long life battery.

一般地讲，电池是把化学能转换成电能的装置并且已研制了各种电池。电化学电池一般分成不可充电的原电池、可充电的二次电池、把碳氢化合物的燃烧热量转换成电能的燃料电池以及转换光能成电能的太阳能电池。电化学电池由电解质的组成和电池的形状分类。电解质的组成和形状分别是碱性、固体或非水溶液电池和圆柱、扭扣或硬币形。In general, a battery is a device that converts chemical energy into electrical energy and various batteries have been developed. Electrochemical cells are generally classified into non-rechargeable primary batteries, rechargeable secondary batteries, fuel cells that convert the combustion heat of hydrocarbons into electrical energy, and solar cells that convert light energy into electrical energy. Electrochemical cells are classified by the composition of the electrolyte and the shape of the cell. The composition and shape of the electrolyte are alkaline, solid or non-aqueous solution battery and cylinder, button or coin shape respectively.

在这些种类电池中，圆柱形电池(胶体—圆筒形)释放电流，并且由阴极、阳极、防止阴阳极短路的隔板、电解质、正极端子和负极端子构成。为具体说明，图5表示了镍氢电池的结构。Among these kinds of batteries, a cylindrical battery (colloid—cylindrical shape) discharges electric current, and consists of a cathode, an anode, a separator to prevent short-circuiting of the cathode and anode, an electrolyte, a positive terminal, and a negative terminal. For specific illustration, FIG. 5 shows the structure of a nickel-metal hydride battery.

圆柱形镍氢电池由涂覆有正极活性材料Ni(OH)2的阴极(13)、涂覆有主要由LaNi5、MnNi5、Ti-Fe或Ti-Ni合金组成的负极活性材料的氢化合金阳极(15)、防止阴极(13)和阳极(15)短路的由无纺织物和玻璃纸带制成的隔板(17)、作为正极端子的盖帽(19)、和作为负极端子及包装装置的外壳(11)组成，以及垫圈(21)、安全孔(23)、盖板(25)、绝缘管(27)和绝缘片(29)。Cylindrical Ni-MH batteries consist of a cathode (13) coated with a positive active material Ni(OH) 2 , a hydrogenated alloy coated with a negative active material mainly composed of LaNi 5 , MnNi 5 , Ti-Fe or Ti-Ni alloy Anode (15), separator (17) made of non-woven fabric and cellophane tape to prevent short circuit of cathode (13) and anode (15), cap (19) as positive terminal, and as negative terminal and packaging device The shell (11) consists of a gasket (21), a safety hole (23), a cover plate (25), an insulating tube (27) and an insulating sheet (29).

下面详细描述根据上述方法制造的圆柱形镍氢电池的充放电反应。The charging and discharging reactions of the cylindrical nickel hydrogen battery manufactured according to the above method will be described in detail below.

氢化合金用作负极活性材料，氢氧化镍用作正极活性材料以及氢氧化钾水溶液用作电解质。氢化合金在充电过程期间存储电解质中由水离解所产生的氢离子，并且在放电过程期间释放氢离子到电解质中。充放电反应如下。A hydrogenated alloy was used as a negative electrode active material, nickel hydroxide was used as a positive electrode active material, and an aqueous potassium hydroxide solution was used as an electrolyte. The hydrogenated alloy stores hydrogen ions generated by water dissociation in the electrolyte during a charge process, and releases hydrogen ions into the electrolyte during a discharge process. The charge and discharge reactions are as follows.

在上述反应中，M是能吸收和放出氢离子的氢化合金，指由稀土元素构成的AB5系或由Ti、Zr、V等构成的AB2系。根据上述反应，电池进行充放电超过数百次。In the above reaction, M is a hydrogenated alloy capable of absorbing and releasing hydrogen ions, and refers to the AB 5 series composed of rare earth elements or the AB 2 series composed of Ti, Zr, V, etc. Based on the above reactions, the battery is charged and discharged more than hundreds of times.

下面是制造圆柱形镍氢电池的工艺。首先，通过在金属支承件(栅格)上涂覆正极活性材料膏剂、干燥和辊压来制造阴极，然后通过在金属支承件上涂覆负极活性材料膏剂、干燥和辊压来制造阳极。此后，隔板置于阴极和阳极之间并卷绕。在卷绕中极板和隔板的组件插入一容器外壳内。此后，电解质注入该容器外壳内并且盖帽组件固定在上部开口中。The following is the process of manufacturing a cylindrical NiMH battery. First, a cathode was fabricated by coating a positive active material paste on a metal support (grid), dried, and rolled, and then an anode was fabricated by coating a negative active material paste on a metal support, dried, and rolled. Thereafter, the separator was placed between the cathode and anode and wound. The plate and separator assembly is inserted into a container shell during winding. Thereafter, electrolyte is injected into the container shell and the cap assembly is secured in the upper opening.

如图1所示，由隔板(17)分开的阴极板(13)和阳极板(15)用Mandrell卷绕法卷绕成螺旋形。卷绕极板插入一容器外壳，电解质注入该容器壳内及盖帽组件固定在上部开口中。因为用一层隔板绝缘并卷绕的镍氢电池具有低装配比(packing ratio)，所以表现出高容量。然而，因为隔板由于阴极板的毁损或顶凸而被撕下，在中心，即卷绕期间卷绕极板的末端处存在短路问题。As shown in Fig. 1, the cathode plate (13) and the anode plate (15) separated by the separator (17) are wound in a spiral shape by the Mandrell winding method. The coiled plate is inserted into a container shell into which electrolyte is injected and a cap assembly is secured in the upper opening. Since the nickel-metal hydride battery insulated with a separator and wound has a low packing ratio, it exhibits a high capacity. However, since the separator is torn off due to damage or protrusion of the cathode plate, there is a short circuit problem at the center, that is, the end of the wound plate during winding.

近来，为解决由图1所示的一层隔板绝缘和卷绕的卷绕极板组的问题，如图2所示，由具有隔板部分(31)的两层隔板绝缘和卷绕的卷绕极板组降低短路的发生约30％。然而，此组卷绕极板存在增加装配比的问题。Recently, in order to solve the problem of the coiled plate group insulated and wound by one layer of separator as shown in Fig. 1, as shown in Fig. The wound plate set reduces the occurrence of short circuit by about 30%. However, this set of wound plates has a problem of increasing the assembly ratio.

本发明目的是提供一组卷绕极板，能防止内部短路、降低装配比、以及提高生产率、容量和循环寿命。The object of the present invention is to provide a set of wound pole plates capable of preventing internal short circuit, reducing assembly ratio, and improving productivity, capacity and cycle life.
