BATTERY, ELECTRODE THEREOF, AND METHODE THEREOF

摘要

PURPOSE: A lead accumulator, an electrode thereof, and a manufacturing method thereof are provided to secure mass energy of 38~41 Wh/kg and volume energy of 103~113wh/dm^3. CONSTITUTION: An electrode of a lead accumulator comprises nano carbon and lead powder. A method for manufacturing the electrode for lead accumulators comprises the following steps of: mixing powder in purified water or sulfuric acid and kneading paste; and coating the paste on a collector and aging and drying the paste for a certain time to obtain aged active material. In the paste-kneading step, a nano carbon suspension is added by 0.1-10.7wt% of the lead powder. The weight of the nano carbon in the nano carbon suspension is 0.1-4%. The lead accumulator employs the electrode.
