The battery memory effect refers to the reversible failure of the battery, that is, the performance that can be restored after the battery fails. The battery automatically maintains this specific tendency after being subjected to a specific duty cycle for a long time. In layman's terms, the battery remembers the node of the last charge and discharge, resulting in the failure to break through this node in the future, resulting in a reduction in battery capacity.

In the traditional flooded lead-acid battery, the separator only acts as an inert spacer to prevent the short circuit of the positive and negative electrodes. It needs to have good ionic conductivity, the manufacturing method is matched with the production process, the physical and chemical properties have long-term stability, etc.
