Abstract

Development was made of a linear motor car use battery which is strong in repetition of quick charging/discharging and characterized as follows: Its volumetric energy density is 42Wh/kg which is 1.3 times as high as the conventional one. It excels in high efficiency charging/discharging characteristics. High tension steel sheet is used for it, which is incombustible. To lighten the weight, paste type electrodes and high yield point materials were used for the positive and negative electrodes, and jar materials, respectively. To heighten the charging/discharging characteristics, used were electrodes heightened in current collecting effect. To lengthening the life, unwoven nylon cloth was used as a separator. Also to heighten the thermal discharge characteristics, the electrodes were made metallic with a fitting of cooling fins. The battery characteristics as tested gave the following result: At a capacity ratio of 100%, the discharging factor cleared its target value of development also with a high discharging voltage. The charging/discharging characteristics hardly fall in the high temperature region. The charging characteristics include quick charging made possible. As a result of cyclic simulation presuming the linear motor car, the fall in capacity per cycle was as good as 1.5%. 11 figs., 2 tabs.
