【摘要】：近期的雾霾天气已成为人们生活中不可逃避的环境问题。如何加强环境保护，减小污染，成为目前尤为重要的问题。相对一次能源，二次能源具有污染小，使用便捷等优点，在现代社会中具有重要作用。铅酸蓄电池相较于锂电、燃料等其他化学电源具有使用安全、性能稳定等优点。铅酸蓄电池可用于各种机动车中，可起到节能环保，减少尾气排放等作用。随着科技的不断发展，人们对铅酸蓄电池性能的要求也随之提高。尤其在初容量及低温容量等方面提出更高的要求。这些问题主要与铅酸蓄电池负极的性能有密切关系。 为此本文进行两方面的探索：一、将碳纳米管代替铅酸蓄电池负极中的乙炔黑；二、将对氮蒽蓝代替负极中的木素；并分别进行物理表征和电化学测试，根据实验结论来衡量这两种负极添加剂对铅酸蓄电池各项性能的具体影响。 本文通过手工和膏涂板的方式制成负极生极板，送工厂流水线，根据工厂生产工艺，装配成6DZM-12的成品电池。实验通过SEM和XRD观察负极添加剂及负极生极板的具体形貌；并通过对电池的容量、低温性能等电化学测试，来考察添加剂对电池各项性能的具体影响。 碳纳米管添加剂的实验结果表明，不同型号碳纳米管均可提高电池的性能，其中TNM2型碳纳米管在三种碳纳米管(TNM2、TNM5、TNM8)中性能表现最为好，，建议最佳添加量为3‰。此时电池的初容量、-15℃低温容量、大电流3C放电时间分别可提高6.2%、15.3%、13%；电池的容量保持率最高可达92.4%。同时也将TNM5、TNM8型碳纳米管进行同样测试，结果显示，TNM5型碳纳米管的最佳添加量为2‰，TNM8型碳纳米管的最佳添加量为4‰。 对氮蒽蓝添加剂的实验结果表明，不同含量的对氮蒽蓝能在不同程度上提高电池性能，当添加量为3‰时，电池的-15℃低温容量可提高29.2%，且电池的初容量、大电流性能均比常规电池有显著提高，因而建议3‰的添加量作为参考值。 总的来说，这两种负极添加剂均可对电池的整体性能产生利好影响，且建议添加量在常规用量范围内，因此可以作为工业生产的参考值。
