A METHOD FOR PREPARING ANODE PLATE OF LEAD STORAGE BATTERY USING ACTIVATED MATERIAL CURED AT HIGH TEMPERATURE

摘要

PURPOSE: An anode plate of the lead storage battery using active materials is provided to achieve high transformability of active materials in a positive electrode and to improve initial capacity of a cell. CONSTITUTION: The method for manufacturing an anode plate is comprised of the first step for molding the mixture of crushed lead and lead oxide, glass fiber, water and sulfuric acid; the second step for coating an electricity collecting body to make the mixture, maturing, and drying to prepare matured active materials containing quadribasic lead sulfate; the third step for transforming the active materials to lead dioxide by applying electricity to the dried active materials. Also, the transforming step is composed of a low-voltage transformation step that can be performed in a short time and optionally, a lengthy transformation step, and charge-discharge repeating step for discharging within the limit of lead dioxide discharge amount and repeating charging procedure twice for making more than 100% of the discharged amount.
