无机添加剂对铅蓄电池充放电过程的影响

Effect of Inorganic Additives on the Charge and Discharge Processes in Lead Battery

通过充放电曲线法研究无机添加剂对铅蓄电池充放电过程的影响。研究发现，硫酸钠添加剂对恒电流放电容量的影响分为两个阶段，在循环初期使电池放电容量增大，但在循环后期使放电容量减小；硫酸镉添加剂使电池在恒电流条件下放电容量增大；硫酸铍和硫酸铵在整个循环过程中均使放电容量减小。

The effect of inorganic additives on the charge and discharge processes in lead battery has been investigated by the charge and discharge curve method. The results show that the additive Na 2SO 4 can increase the discharge capacity within 20 cycles, but after 20, it decreases the capacity, CdSO 4 increases the capacity, both (NH 4) 2SO 4 and BeSO 4 reduce the capacity in all cycle processes.
