添加硬脂酸钡的富液式汽车免维护电池的性能

摘要

硬脂酸钡与木素磺酸钠匹配会对富液式汽车免维护电池的低温起动性能有负面影响.采用木素磺酸钠作为负极有机膨胀剂,加入硬脂酸钡作为抗氧化剂前后的6-QW-60型电池,储备容量分别为104 min和103 min,C20容量放电时间分别为1 278 min和1 258 min,但-18℃下的5.00 C放电时间由96s降低到76 s.%The compatibility of barium stearate and sodium lingo sulphonate had negative effect on the cold cranking performance of maintenance-free flooded car battery. When using sodium lingo sulphonate as negative organic expander, the reserve capacity of the prepared 6-QW-60 battery before and after adding barium stearate as antioxidants was 104 min and 103 min,respectively,the C20 discharge time was 1 278 min and 1 258 min,respectively,but the 5.00 C discharge time at - 18 t decreased from 96 s to 76 s.
