Abstract: LEAD ACID BATTERIES TUBULAR POSITIVE ELECTRODES ASSEMBLED WITH NANOMETRIC ACTIVE MATERIAL.Conventional stationary lead acid batteries positive tubular plates have a specific capacity of about 120 Ah/kg.This value represents an active material utilization coefficient of 50%.The production of these plates includes some initial processes to generate the active PbO 2 from a precursor material.In the present work it will be presented a proper and novel methodology to assemble tubular plates directely with nanometric powder of PbO 2 particles.The utilization coefficient of these plates was about 80%, and they were able to endure more than 130 severe duty cycles.This high utilization coefficient is a higly desirable feature for electric vehicles batteries.
