Abstract
Pulse power batteries based on the high-temperature Lithium-Metal Sulphide (LiMS) system are of interest for miliary applications. However, improvements in minimized size, maximized power density, maximized life, and reduced cost are needed to meet all Army requirements. Many of the battery components required for these improvements have been demonstrated, but they have not been integrated into an advanced technology unit. Furthermore, improvements related to thickness minimization and cell stability have been related to the separator plate, but have not been demonstrated. Development of thin, porous aluminum nitride separator plates for improved LiMS batteries is proposed. This development will be based on existing fabrication technology for sintered, porous shapes. Further reduction in thickness will be obtained by improvements in fabrication as well a sintering technology. Thin separator cells will be infiltrated with electrolyte, then tested in single and multi-stack cells. All cell evaluation will be performed at the battery test facility at Westinghouse. Successful completion of Phase I will provide the required plate technology for integration with improved battery chemistry an system technology available at Westinghouse. While this technology is suitable for military applications, commercial applications such as electric vehicles will also be positively impacted.
