“…Accordingly, the complete conversion of PbSO 4 at the plate surfaces cannot be achieved even with an overcharge due to the combined effects of the early evolution of H 2 and the O 2 -recombination reaction. This leads to rapid accumulation of PbSO 4 on the negative plate leading to early failure of the lead-acid battery [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28].…”

Positive-and negative-limited lead-acid cells with conventional and polyaniline (PANI)-coated negative plates were assembled and tested at varying discharge rates. The cells with PANI-coated negative plates exhibit lower impedance in relation to conventional cells and sustain higher discharge-rates with lesser loss in capacity during prolonged charge-discharge cycling as compared to conventional cells. It is suggested that PANI-coated negative plates are beneficial in designing lead-acid batteries operating at partial-state-of-charge.

“…The curve obtained for the Pb electrode has an anodic peak Al, and a cathodic peak C1. The anodic peak A1 has an onset potential of -0.68 V, may be due to the formation of t-PbO:1° P b + 20H-=t-PbO + H2O + 2e-E, (vs. Hg/HgO) = -0.678 V at 25'C1' (1) Vol. 14 The cathodic peak of C1 may correspond to the reduction of t-PbO to Pb.…”

A b s t r a c t The composition and properties of the anodic films formed on P b and Pb-3at.xSb alloy at -0.10 V (vs. Hg/HgO) for 2.5 h in 0.1 mol.dmT3 NaOH solution (25OC) were investigated by cyclic voltammetry, linear sweep voltammetry, open circuit decay curve, photocurrent technique, X-ray diffraction (XRD) and scanning electron microscopy (SEM). It was found that the anodic film iormed on P b mainly consists of t-PbO, while that on Pb-3at.%Sb consists of o-PbO, t-PbO and a small amount of orthorhombic SbzO3. The dominant component of the film anodically grown on Pb-3at.%Sb for less than 5 min is o-PbO, however, t-PbO is the major component of the anodic film formed for 1 h or longer. It is estabbhed that Sb suppresses the growth of t-PbO. The anodic film formed on Pb-3at.%Sb is less porous than that on Pb. The bandgap energies of t-PbO and o-PbO in the films were determined by photocurrent measurements to be 1.83-1.84 eV and 2.60 eV, respectively. Keywords Anodic Pb(I1) oxide film, lead, Pb-Sb alloy E x p e r i m e n t a l Cyclic voltammetry (CV), linear sweep voltammetry (LSV) and open-circuit decay curve (OCD) methods were carried out using a PAR Model 273 potentiostat/galvanostat
