这种蓄电池在实际车辆使用过程中，一般都是外面两片正极板翘曲，穿透相邻的隔板而造成短路。
In actual car service of such batteries, the two outside positive plates were generally buckled and shorting through the adjacent separators.
本研究中PVDF粘结剂的添加量在7一10%，乙炔黑导电剂的添加量在8%左右，正极极片的性能最佳。
When the amount of PVDF and acetylene black is 7~10% and 8%, the positive plate obtained possesses optimum properties in our studies.
通过对比实验，选择了多孔结构的集流片并确定了正极板厚度为0。
By contrast experiment porous structural collector was chosen and the electrode thickness of 0.
