RESEARCH AND DEVELOPMENT OF ADVANCED LEAD-ACID BATTERIES FOR ELECTRIC VEHICLE PROPULSION: 1986 ANNUAL REPORT, DECEMBER 1985-MARCH 1987

Purpose was to develop an advanced lead-acid battery based on the concept of forced flow of electrolyte through porous electrodes for enhanced battery performance 1986. Objectives were: specific energy of 42 Wh/kg, energy density of 70 Wh/l, and cycle life of 100 cycles. Accomplishments were: 35 flow-through cells with reduced construction time, higher fiber content in the positive active materials (PAM) with increased strength by a factor of 3, high-density PA for increased life without utilization losses, confirmation of solid-state relaxation theory, methods for measuring permeability, 31 cycles achieved in C-450, oxygen recombination in many test cells, electrolyte reservoir can be below the top of the cells, and completed designs for positive and negative flow-through grids and for the injection molds to produce the grid/plastic laminates.
