Lithium battery plate extrusion line

rcharging. At this time, the positive electrode active material is subject to the impact of the gas, and this impact will promote the fall of the active material. In addition, the positive electrode grid alloy also Suffering from severe anodic oxidation and corrosion, so the battery will shorten the application period when the battery is overcharged. The depth of discharge, because the positive electrode active material lead dioxide itself is not well integrated with each other, lead sulfate is generated during discharge, and it returns to lead dioxide during charging. If the molar volume of lead sulfate is larger than that of lead oxide, the volume of the active material will expand during discharge. If one mole of lead oxide is converted into one mole of lead sulfate, the volume will increase by 95%. In this way, repeated contraction and expansion will cause the lead dioxide particles to The mutual bonding of the particles gradually relaxes and is easy to fall off. If only 20% of one mole of the active mate
