To date, there is no emerging and friendly reserve battery system(s) that could replace the Li/oxyhalide technologies until Phase I of this program. Primary solid cathode systems, e.g., l-MnO2 , Li0.55CoO2 and Li0.55CoO2(2%TiO2), have demonstrated fullcapability in meeting the Multi-Option Fuse Artillery (MOFA) electrical load profile and at temperature as low as -200C in organic-based electrolyte environment. These systems have also shown to be very compatible to the Li/oxyhalide systems with respectto their high voltage and high power capabilities. When successfully developed, these solid-cathode, organic-based reserve systems will provide the U.S. military an alternate reserve battery technology that is not only performance capable, but alsoenvironmentally and production friendly.Phase II of this program will see the development of prototype reserve batteries utilizing solid cathode and organic-based electrolyte solution. It will focus on the development of the following tasks: I. Cathode Development and Optimization, which willemphasize rate enhancement by way of cathode formulations and processing; II. Electrolyte Development and Optimization, which will target meeting -430C and lower; and III the Development of Two Reserve Prototype Hardware, the HED which utilizes the glassampuls, and the MOFA which utilizes the metal reservoirs. Cell system long term stability will also receive focus since this is a critical area of any reserve batteries.Ambient-temperature lithium reserve battery is a critical component of many military applications. It is a key technology, for example, for the U.S. Army''s and Navy''s MOFA (Multi Option Fuse Artillery) programs. The proposed organic-based and solidcathode-based reserve battery technology, if successfully developed and engineered, can be a direct replacement of any reserve batteries that currently use the primary lithium/oxyhalide chemistries. It will also thrusts this proposed technology for usagein strategic
