View moreSci., 9 (2014) 4826 - 4839 Positive plates for the carbon lead-acid battery (CLAB) with porous carbon grids coated with lead have been prepared and tested. Lead coating thickness in the range between 20 and 140 micrometers has been shown to positively influence the discharging profile and the cyclic lifetime of the plates.
In the early days of lead–acid battery manufacture, an electrochemical process was used to form the positive active-material from cast plates of pure lead. Whereas this so-called ‘Planté plate’ is still in demand today for certain battery types, flat and tubular geometries have become the two major designs of positive electrode.
The positive active-material of lead–acid batteries is lead dioxide. During discharge, part of the material is reduced to lead sulfate; the reaction is reversed on charging. There are three types of positive electrodes: Planté, tubular and flat plates.
This Al/Pb electrode has a smooth surface, firm combination, stable electrochemical properties that can meet the application requirements of high concentrations sulfuric acid system like lead-acid battery. Performance characteristics of 2.0 V single-cell flooded lead-acid batteries with Al/Pb electrodes as negative collectors were investigated.
In addition, cycle life of the Al/Pb-grid cell was about 475 cycles that could meet the requirement of lead-acid batteries. The present study suggests that Al/Pb composite material produced by molten salt electroless deposition is suitable for negative grid of lead-acid batteries, if the welding problem of plate terminal is resolved.
CONCLUSIONS The results of this work show that the perspective of designing lead-acid batteries with significantly reduced weight is possible. Experiments showed that positive plates employing lightweight RVC/Pb grids can be prepared employing industrial methods and work successfully in the lead-acid batteries.
