A novel cureless paste for positive plates in valve-regulated batteries

A new manufacturing technique for positive plates for valve-regulated lead–acid batteries has been developed. This involves a novel paste-preparation method which employs hydrogen peroxide to replace the traditionally used sulfuric acid. After pasting, the plates can be assembled into groups and placed directly into a battery case. Formation can then be performed without the plates undergoing the conventional curing process. Such a non-curing process could reduce production time and costs. More importantly, the resulting plates provide good flexibility which is particularly suitable for spirally-wound battery designs.
