Valve-regulated sealed lead-acid batteries (VRLA) mainly adopts lead-calcium alloy pole plate, relative to the pregnant solution type lead acid accumulator adopting lead-antimony alloy, the deeper cavity life-span of valve-regulated sealed lead-acid batteries is generally on the low side, and reason is that grid interface passivation phenomenon easily appears in the positive plate of lead-calcium alloy in cyclic process.At present, solution is except adding the elements such as tin, silver, rare earth in the alloy, another prior way adjusts polar plate solidification technique exactly, grid interface is made to form densification and firmly corrosion layer, thus the grid interface passivation phenomenon that the positive plate eliminating lead-calcium alloy occurs in cyclic process.But current industry does not also have ideal method, the battery pole plates prepared can deeper cavity life-span of significantly lift valve controlled sealed lead-acid storage battery.
Summary of the invention
The present invention in order to deeper cavity life-span of solving existing valve-regulated sealed lead-acid batteries (VRLA) technical problem on the low side, propose a kind of can the method for battery pole plates solidification in deeper cavity life-span of lift valve controlled sealed lead-acid storage battery.
The present invention propose a kind of can the polar plate solidification method in lift valve control sealing type lead-acid battery deeper cavity life-span, its procedure of processing is as follows:
Step 1: select lead plaster according to demand, and this lead plaster is coated battery pole plates surface;
When the battery pole plates of described coating lead plaster takes up, battery pole plates closely hangs up or stacks, and does not stay gap between battery pole plates, and the water content of battery pole plates surface lead plaster is greater than 9.5%, and the temperature of battery pole plates is less than 45 DEG C;
Step 2: the battery pole plates of described coating lead plaster is carried out first stage solidification, curing temperature is 45 DEG C ~ 55 DEG C, humidity more than 99%, circulation wind speed 25% ~ 35%, 12 ~ 24 hours time;
Step 3: the battery pole plates of described coating lead plaster is carried out second stage solidification, curing temperature is 45 DEG C ~ 65 DEG C, and humidity drops to 60% ~ 50% gradually from 99%, circulation wind speed 30% ~ 50%, 24 ~ 48 hours time;
Step 4: the battery pole plates of described coating lead plaster is carried out drying process, stop humidification, temperature is risen to 65 DEG C ~ 75 DEG C, circulation wind speed is 80% ~ 90%, 12 ~ 36 hours time.
Preferably, the battery pole plates of described coating lead plaster, the positive plate free lead content after solidification is 0.2% ~ 2%, moisture 0.1% ~ 0.3%; Negative plate free lead content is 0.2% ~ 3%, moisture 0.1% ~ 0.3%.
Knock out the lead plaster of the battery pole plates after solidification, can obviously see grid surface completely by one deck firmly corrosion layer wrap up, show that corrosion layer is good.Adopt battery pole plates of the present invention to assemble conventional VRLA battery, 20 hour rate electric discharges reach 22 hours, and initial 1C reaches 40 minutes discharge time, and 1C discharge cycles 360 times, discharge time steadily remains on 43 ~ 45 minutes always, undamped.By 10 hour rate 100%DOD discharge cycles, circulate still have for 60 times more than 90% capacity.The present invention, by improving polar plate solidification technique, improves the deeper cavity life performance of the valve-regulated sealed lead-acid batteries adopting lead-calcium alloy greatly.
