Embodiment 1
[0031] A long-life lead-acid storage battery positive plate formation method, the specific implementation is as follows:
[0032] a) Standing stage: After injecting the electrolyte into the battery, put the battery in a water bath for 1 hour;
[0033] The temperature of the water bath is controlled below 15°C, and the battery temperature is guaranteed to be between 20-50°C during the entire formation stage.
[0034] b) Formation stage:
[0035] b1: Charge with 0.4A (electric vehicle battery capacity C2=20Ah, so current I=0.02C2=0.02*20=0.4A) constant current for 0.5h, then charge with 5A constant current for 14h, and stand still for 1h for the first time;
[0036] b2: Charge with 5A constant current for 6h, and rest for 1h for the second time;
[0037] b3: Charge with 5A constant current for 5h, and rest for 1h for the third time;
[0038] b4: Charge with 5A constant current for 5h, and rest for 0.5h for the fourth time;
[0039] b5: Charge with 4A constant current for 3h,...

[0047] b) Formation stage:
[0048] b1: Charge with 0.4A constant current for 0.5h, then charge with 4A constant current for 15h, and rest for 0.5h for the first time;
[0049] b2: Charge with 4A constant current for 8h, and rest for 0.5h for the second time;
[0050] b3: Charge with 4A constant current for 7h, and rest for 0.5h for the third time;
[0051] b4: Charge with 4A constant current for 5h, and rest for 0.5h for the fourth time;
[0052] b5: Charge with 4A constant current for 4h, and rest for 1h for the fifth time;
[0053] b6: Discharge at a constant current of 7.5A until the voltage of each battery is 9-10V / pc;
[0054] b7: Charge with 4A constant current for 8h, then charge with 4A constant current for 4h;
