Research on constant pressure curing process for plates of valve regulated lead-acid batteries
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.
