Research and development of advanced lead-acid batteries for electric vehicle propulsion
The US Department of Energy sponsors a number of research and development activities that have a common goal, the demonstration of advanced batteries that meet the energy, power, and life requirements needed to make electric vehicles a viable alternative to fuel-powered vehicles. An advanced lead-acid battery is one of the technologies being pursued for near-term applications. To this end, Johnson Controls, Inc. (JCI) began work in December 1985 on a new cell concept based on continuous electrolyte recirculation to boost the level of performance beyond the capabilities of conventional lead-acid technology. Superior levels of power and energy were demonstrated for both the flow-through and the more recent flow-by cell designs in the initial years of this program. The cycle-life of these cells, however, fell short of the target for acceptable life. This report summarizes JCI's technical efforts during the period May 1989 to May 1990. During this interval, JCI concentrated on two activities, further research to identify factors that cause and contribute to low cycle-life and continued engineering to evaluate new cell designs. 5 figs., 5 tabs.
