    • Disclosed is a battery including a cathode and an anode wound to face each other with a separator interposed therebetween. Both surfaces of a cathode collector are provided with cathode active-material coating layers so as not to provide a cathode uncoated part at a winding beginning portion of the cathode. The cathode uncoated part for installation of a cathode lead is provided only at a winding ending portion of the cathode. An insulator tape is attached to the boundary of the cathode active-material coating layer facing the anode at the winding ending portion of the cathode. Providing the insulator tape to the boundary of the cathode active-material coating layer at a position where a non-coating part not containing the cathode active-material coating layer and an anode active-material coating layer face each other achieves enhanced electrical insulation capability and consequential safety of the battery.
    • 公开了一种电池,其包括阴极和阳极,其间隔开隔离件彼此面对。 阴极集电体的两个表面设置有阴极活性材料涂层,以便在阴极的卷绕开始部分处不提供阴极未涂覆部分。 用于安装阴极引线的阴极未涂覆部分仅在阴极的卷绕结束部分处提供。 在阴极的卷绕结束部分处,阴极活性材料涂层的面向阳极的边界附着绝缘胶带。 在不含阴极活性材料被覆层和负极活性物质覆盖层的非涂布部位彼此面对的位置处,在阴极活性物质被覆层的边界上设置绝缘体带,能够提高电绝缘性, 电池的相应安全性。

    • The present invention relates to a method of measuring residual capacity of a Ni/MH (nickel/metal hydride) cell by measuring the change in the electrical resistivity of a Ni/MH cell according to the change of the concentration of hydrogen in metal hydride. According to the present invention, a method for measuring residual capacity of a Ni/MH cell comprises the steps of measuring electrical resistivity of a first Ni/MH cell, and determining the residual capacity of the first Ni/MH cell (i) from a predetermined data of n-pairs of electrical resistivity values and residual capacity values of a second Ni/MH cell which has substantially the same composition as the composition of the first Ni/MH cell, or (ii) based on a predetermined functional relationship between the electrical resistivity and residual capacity of the second Ni/MH cell. The series of the predetermined data or the predetermined functional relationship represents substantially a linear proportionally between the resistivity and the logarithmic value of the residual capacity. As the discharge reaction proceeds in the cell, metal hydride in the anode is reduced and loses hydrogen, and thus the hydrogen concentration at anode becomes lower. Accordingly, the relationship between the residual capacity and the resistivity of a Ni/MH cell can be obtained by measuring the residual capacity and the resistivity of the cell depending on the degree of discharge, therefore the residual capacity can be readily detected by measuring only the resistivity of the cell.
    • 本发明涉及一种通过根据金属氢化物中的氢浓度的变化来测量Ni / MH电池的电阻率的变化来测量Ni / MH(镍/金属氢化物)电池的残余容量的方法。 根据本发明,用于测量Ni / MH电池的剩余容量的方法包括以下步骤:测量第一Ni / MH电池的电阻率,以及从第一Ni / MH电池确定第一Ni / MH电池(i)的剩余容量 具有与第一Ni / MH电池的组成基本相同的组成的第二Ni / MH电池的n对电阻率值和剩余容量值的预定数据,或者(ii)基于第一Ni / 第二Ni / MH电池的电阻率和剩余容量。 预定数据或预定功能关系的一系列在电阻率与剩余容量的对数值之间基本成比例地表示线性。 随着电池中的放电反应进行,阳极中的金属氢化物减少并且损失氢,因此阳极中的氢浓度变低。 因此,可以通过根据放电度测量电池的剩余容量和电阻率来获得Ni / MH电池的残留容量和电阻率之间的关系,因此可以容易地通过仅测量电池容量来检测剩余容量 电池的电阻率。
