A design for an improved state-of-the-art (ISOA) battery is proposed in this report. It is believed that this ISOA design is the most efficient design achievable within the constraints of the ISOA battery development program. These constraints include realistic time and financial limitations, and compatibility with existing high-speed production equipment. The ISOA battery is in fact an improved, state-of-the-art lead--acid battery suitable for use in an electric vehicle. A durable, light-weight polypropylene container and cover complete with single-point watering and venting features are incorporated in the ISOA design. A number of materials and process parameters with profound affect on battery performance will be chosen only after extensive evaluation and cell testing. Development of an advanced lead--acid electric vehicle battery will involve the evaluation and application of effective forward concepts in the design of the battery. Many weight-saving designs will be incorporated. Significant improvements in active material efficiencies and integrity are required. The goals of 60 Wh/kg and 1000 life cycles are ambitious but achievable. The cycle life goal appears to be the most formidable. Investigations of charging equipment and parameters will be undertaken. The impact of manufacturing plants on the environment and natural resources is discussed. (ERA citation 03:003915)
