摘要
为稳定极板固化过程中的各项参数,提高阀控式铅酸蓄电池极板性能,采用恒压 400 kPa、温度 75℃固化 6 h,恒压 300 kPa、温度 55℃固化 8 h 和 50℃固化 4 h 的极板固化工艺.所制备的极板性能均衡,铅膏中游离铅含量不大于 1.40%.所制备的电池实际容量提高约 7.1 Ah且均衡性好,循环耐久能力提高约 61 次.
Abstract
In order to stabilize the parameters of the plate curing process and improve the performance of plate of the valve regulated lead-acid battery,the plate curing process of constant pressure 400 kPa,temperature 75℃ curing for 6 hours,constant pressure 300 kPa,temperature 55℃ curing for 8 hours and 50℃ curing for 4 hours was adopted.The prepared plates have balanced performance,and the free lead content in the lead paste is not more than 1.40％.The actual capacity of the prepared battery has been increased by about 7.1 Ah with good balance,and the cycle durability has been improved by about 61 cycles.
