In order to meet these demands, constant technological innovations are being carried out, such as thinner electrode plates and ultra-thin separators.In order to make the bridge plate thinner, the weight of the grid has been made lighter than before. However, experiments have shown that it is possible to significantly reduce the weight of the grid without reducing battery performance, and the reduction of the weight of grids and the spread of grid bars in this field have become active. However, with the improvement of the brightness of the grid bars, a serious problem has arisen in that the active material easily falls off during the battery assembly process, increasing the defective rate.

活物質保持性能を示すことがわかる。Using six types of lead powder with different lead powder compositions, a light grid for automobiles and automobile batteries was filled with a paste prepared according to the formulation of a normal automobile battery base, and the paste was left to mature for two days. Using each of the electrode plates obtained in this way, the frequency of vibration is 2000 minutes, the degree of addition is 5 g, and the amplitude is 21111.
The results of measuring the amount of active material falling off under the condition of S vibration time of 10 minutes are shown in Table 1. , As is clear from Table 1, ]] b0 is 70 to 50
It can be seen that the electrode plate filled with a paste prepared using lead powder having a composition in the range of 30 to 50 wt% and pb exhibits good active material retention performance.
