From the experiment we have found out that the carbon fibre can improve the anode performance when it was used as pam additive and meanwhile it can have some benefits to the anode life . when its content at 0 . 2 - 0 . 3 % in pam can achieve its best result and under this situation it can improve the utilization of pam by 5 % at different discharge current . carbon fibre and sulfate sodium is used as complex pam additive and its effect is better than that of carbon fibre which alone is used as additive 通过实验我们发现，碳纤维作为铅酸电池的正极活性物质添加剂能提高铅酸电池正极的性能，并且对电池正极板的寿命有一定的好处，当碳纤维在正极活性物质中的含量为0 . 2 0 . 3能得到最理想的效果，这个时候能在各种不同的放电电流下提高正极活性物质的利用率5左右，并且能够使极板的电化学阻抗降低。
