  • the discharge and charge processes at the negative plate can be expressed by reactions 1 to 4.
  • the conversion of sponge lead to lead sulfate proceeds via two steps.
  • the sponge lead at the negative plate reacts with HSO 4 - to form Pb 2+ , S0 4 2 ⁇ and H + , i.e., the so- called 'dissolution process 1 (reaction 1).

  • the first step is an electrochemical reaction and thus involves electron transfer. Such transfer of electrons takes place only on the conductive sites, i.e., on fresh lead. The rate of the electrochemical reaction is therefore dependent not only on the diffusion of HS0 4 - species, but also on the effective surface-area of the sponge lead.
  • the second step is a chemical reaction and proceeds with a rate which is acid dependent.
  • the solubility of lead sulfate does not increase with increase in sulfuric acid concentration. Rather, it reaches a maximum value at 10 wt.% sulfuric acid (1.07 rel.dens.), and then decreases rapidly with further increase in concentration (Fig. 2) .
  • the Pb 2+ will precipitate as lead sulfate at concentrations above the solubility curve.
  • the deposition (or precipitation) of Pb 2+ to lead sulfate will be faster at plate locations which experience high concentrations of acid.
  • the discharge process both dissolution and deposition steps
  • the reaction in the interior of the plate will soon slow down and/or stop, while that at the surfaces of the plate will continue to proceed. This is because less acid is available in the interior.
  • the depth to which lead sulfate penetrates is dependent on the rate of discharge, as well as on the density and surface area of the plate.
  • Paste density is the key factor in providing the macropores (or 'avenues') which are necessary for the transport of solution and ionicspecies to and from the reaction sites within the interior of the plate, while surface area provides sites for the current-generating electrochemical reaction.
  • the extent to which lead sulfate can penetrate is determined by the discharge rate.
  • the deposition rate of PbS0 4 is proportional to the degree of supersaturation of Pb 2+ in the sulfuric acid solution, i.e., the higher the supersaturation, the faster is the deposition rate.
  • the rate of deposition (reaction 2) is slow, newly formed PbS0 4 tends to precipitate preferentially on the already-deposited PbS0 4 crystals, i.e., growth rate > nucleation rate. Consequently where there is a low-rate of discharge, the deposited lead sulfate will continue to grow to various sizes of discontinuous crystals 10, both on the surface 10a and in the interior 10b of the negative plate.
  • This form of lead sulfate is particularly desirable on the surface of the plate, as it provides an open structure that facilitates the ingress of HS0 4 ⁇ ions. Therefore, the discharge process can proceed deep into the interior of the plate. Accordingly, the lead sulfate develops in an even sulfation pattern throughout the cross-section of the negative plate (Fig. 3(a)).

  • the recharge mechanisms are as follows. Firstly, recharge of the negative plate after it has been deeply discharged at a low rate occurs after, as mentioned above, lead sulfate is formed throughout the entire cross-section of the plate and the relative density of the acid after discharge is low because of the high utilization of the active material.
  • the dissolution of PbS0 4 to form Pb 2+ and S0 4 2_ increases at the low concentrations (see, Fig. 2) .
  • the subsequent reduction of Pb 2+ to sponge lead can take place smoothly before the evolution of hydrogen.
  • an overcharge factor of ⁇ 10% the plate can be brought to a fully-charged state without any difficulty. This is also true when the plate is subjected to low-rate PSoC cycling with equal amounts of charge input and charge output. In such duty, the SoC of the negative plate decreases with cycling, but can be brought to 100% after the application of an equalization charge.
  • the inventors have determined that the cycleability of batteries can be increased if current can be directed to the battery in a manner consistent with the sulfation pattern and in particular, the cycleability of VRLA batteries under HRPSoC duty can be enhanced if, during charging, current can be concentrated on the surfaces of the negative plates.
