This report contains two detailed designs, and the design rationale, for an improved state-of-the-art electric vehicle battery incorporating expanded metal grids. The nominal 96-volt and 20-kWh battery incorporating this improved design is expected to cost about 25% less when manufactured in a mature plant. This report also contains detailed estimates for the capital cost and operating cost of a pilot plant to produce electric vehicle battery plates incorporating expanded metal grids. It is expected that the first electric vehicle batteries incorporating expanded metal grids can be available fifteen months after approval of this program. An additional program to improve lead acid batteries for electric vehicles further is also described. The advanced batteries resulting from this program are expected to incorporate either expanded metal grids and/or composite lead/plastic grids. In addition, these batteries are expected to contain low-density active materials. It is anticipated that those additional developments will result in an advanced battery capable of delivering 45 to 50 watt-hours/kg. As a result of the design and cost study, a ''First Buy'' improved state-of-the art vehicle battery proposed is included as part of this report. Eltra proposes to manufacture and deliver the required 2500 vehicle batteries within the time limits set forth by the Electric and Hybrid Vehicle Research, Development, and Demonstration Act of 1976.
