Relationship Between Initial Capacity And Service Life Of Battery

Battery capacity is affected by active material and utilization. The size of the battery of electric bicycles is certain, and the quality of the plate has been limited to a certain extent. Only by improving the utilization rate of active substances can the capacity be increased. To increase the battery capacity, it is necessary to increase the porosity, increase the content of PbO2 and the proportion of sulfuric acid, but these measures will accelerate the softening of the positive plate, resulting in accelerated battery life decay, and the active material will expand and shrink during the charging and discharging process (especially the positive plate). , the deeper the discharge depth, the greater the expansion and contraction of the active material, and the more accelerated the softening of the active material. Therefore, when the initial capacity is too large, it directly affects the charging and discharging times of the battery. Of course, in order to meet the requirements, the initial capacity should not be too small, and a compromise choice is needed to meet the needs, which not only ensures the prolongation of life, but also ensures that the capacity meets the requirements of use.
