摘要：负极活性物质的导电性对铅蓄电池的充电接受性能和深放电循环寿命有着决定性影响。本文采用一种特殊生产工艺的高导电性炭材料OFB1作为负板导电添加剂，制备出2V/4Ah阀控式铅酸蓄电池，并测试了不同OFB1添加量及90%～60%不同荷电状态下动态充电接受性能、50%荷电状态下17.5%DOD深放电循环寿命等相关性能，最后深入探讨了OFB1作为负极导电添加剂对电池综合性能的影响，并得出了当最佳添加量为w(OFB1）=0.6%时，电池的综合性能最优。

In this paper, we choose a kind of high conductivity commercialize carbon material named OFB1 made of special production process as conductive additive of negative electrode to prepare 2 V/4 Ah AGM flat VRLA batteries. We test their dynamic charging acceptance with different OFB1 content at 90 % ~60 % SOC and 17.5 % DOD recycle life at 5o % SOC. Lastly, according to the test data and comparison, we find that the comprehensive performance of VRLA battery is optimal when the amount of OFB1 additive is 0.6 wt% in the negative electrode
