Abstract:
1. A method for producing a lead battery electrode comprising the steps of: (i) depositing of an active paste on a support to form an electrode; (ii) placing said electrode in a controlled atmosphere environment at a temperature between 30° C. and 50° C. and a relative humidity greater than 80% and treating said electrode with an ozone-enriched gas at a flow rate less than 100 liters per hour for each square meter of the electrode, (iii) curing said treated electrode in an environment comprising a temperature between 35° and 65° C. and a humidity of about 90% for a time between 12 to 24 hours, wherein the treatment with said ozone-enriched gas is at a flow rate effective to enhance a capacity of the electrode and the method does not result in formation of lead dioxide on the electrode.
