Embodiment Construction
[0010] Such as figure 1 As shown in the flow chart of the present invention, the steps included in the formation process of the present invention include: first hydrating the plate: the thickness of the grid in this embodiment is a medium thickness, and the hydration is 60 minutes. The thickness of the grid should be properly adjusted, the hydration time of the thinner grid is shorter, and the hydration time of the thicker grid is longer. After testing, the best hydration time is 60 minutes, and grids of various specifications can adapt to this Hydration time; high current charging after hydration: This step is carried out after hydration and before the grid loses water, and the current density used is 11.5mA / m 2 , to the end of the tank voltage 2.37V; then charge with a small current, the current density is 7.5mA / m 2 , to 100% of the theoretical capacity; after the small current charging is completed, the discharge step is carried out to the cell voltage of 1.77V; recharging...
