摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of a pulverizing phenomenon during use by incorporating Yb into an alloy with CaCu5 type crystal structure or MgZn2 type crystal structure, being used as an electrode-activating material for secondary battery and capable of reversibly occluding and releasing hydrogen. SOLUTION: An alloy, prepared by adding Yb by 1 wt.% to an (La, Ce, Ne, Pr) (Ni, Co, Mn, Al)5 composition of CaCu5 type alloy structure, is produced. Further, in the case of an alloy with MgZn2 type crystal structure, Yb is added by 5 wt.% to a (Zn, Ti) (Ni, Mn, V, Cr)2 composition. With respect to a nickel- hydrogen battery cell using the Yb-added alloy with CaCu5 type crystal structure as a cathode, practically no reduction in discharge capacitance is observed and the structure is in a coarse-grained state at 120-times charge and discharge cycle tests at room temp. and at 50 deg.C; on the other hand, in the case of a Yb- free alloy, discharge capacitance is decreased with the increase in the charge and discharge cycle and also the structure becomes fine-grained (pulverized).

摘要： PURPOSE:To predict the residual life of a lead-acid battery easily and correctly and speedily as it is being used. CONSTITUTION:A degree of deterioration of the subject battery is predicted based on a size of a first temperature compensation reference voltage determined by a voltage-current relation obtained in a large current discharge and a battery temperature, and a size of a second temperature compensation reference voltage obtained after a short-time charging. The temperature compensation reference voltage is a value which reflects both an electromotive force and an inner resistance of the battery, so a condition of its deterioration can be grasped correctly regardless of history of the battery. Whether the battery shall be charged, replaced, etc., can be determined objctively by the size of the temperature compensation reference voltage, thereby maintenance of the battery is facilitated.

摘要： PURPOSE:To accurately and promptly detect residual capacity of a lead-acid battery in use state by calculating a reference voltage for temperature compensation at the temperature of battery from the relation between the reference voltage and battery temperature obtained in advance and the reference voltage for temperature compensation. CONSTITUTION:When a power relay 4 comes to the ON state, a large current flows to a starter motor and the current is pulsated in accordance with the rotation of starter motor. The current and voltage at this time are measured respectively by an ammeter 5 and a voltmeter 6. The temperature of electrolyte is measured by a temperature sensor 7 which is inserted in the electrolyte of battery 1. The output of temperature sensor 7 is sent to an arithmetic part 8 together with voltage and current data. In the arithmetic part 8, voltage/current straight lines are decided by the calculation using a method of least squares based an the signal values sent from the voltmeter 6 and ammeter 5. Also, the reference voltage for temperature compensation is calculated from the relational equation among the signal value from temperature sensor 7, the temperature stored in a storage part 9 and a reference current. The residual capacity is obtained from the relation between the obtained reference voltage for temperature compensation and the residual capacity.

摘要： PURPOSE:To easily know the remaining capacity of a battery by measuring a terminal voltage V when the battery is discharged with current density of 100-400mA/cm , a battery current I, and the liquid temperature of the battery, and finding differential internal resistance (V0-V)/I from the reference voltage V0 at the temperature. CONSTITUTION:The relation between the differential internal resistance obtained as a gradient and remaining capacity is found from the V-I (V: terminal volt age, I: battery current) at the time of large current discharging by using plural batteries whose remaining capacities are already known. Further, the tempera ture of the batteries is measured. Then, the voltage V, current I, and the liquid temperature of the battery when the battery is discharged while the discharging current density is 100-400mA/cm are measured to find the reference voltage V0 at the temperature. Further, the differential internal resistance (V0-V)/I is found and the remaining capacity of an optional battery is known from the correlation between the differential internal resistance and remaining capac ity which are already found.
