ABSTRACT:
The battery system and process of the present invention enables the increase of the specific energy of the lead-acid battery by using new starting pastes which will allow significantly higher utilization efficiencies of the positive and negative pastes. The invention enables the increased utilization efficiency of both electrodes, to thereby increase the specific energy of the battery. Two paste combinations have been found to be advantageous. First, a battery has at its positive terminal, a lead sulfate (PbSO.sub.4) paste and at its negative terminal, a tribasic lead sulfate (3PbO'PbSO.sub.4 'H.sub.2 O). In a second combination, a paste of lead sulfate (PbSO.sub.4) is used at the positive electrode and while a monobasic lead sulfate (PbO.PbSO.sub.4), is applied to the negative electrodes.
