The gas-evolution rates from new and end-of-life lead/acid submarine cells at both open-circuit and under float-charge have been examined, together with the discharge performance of the cells. The evolved gas is found to comprise hydrogen and oxygen only. The open-circuit and float-charge hydrogen-evolution rates vary logarithmically with temperature. The enthalpy of activation for open-circuit...
An investigation has been made of the possible application of electrically conductive polymers in efforts toimprove the performance of lead/acid batteries. Results show that the new class of organic compounds may be used as modifiers of the activematerial to suppress self-discharge and irreversible sulfation and to increase the specific capacity of the battery, especially underautomotive discharge...
