Discharge Capacity Improvements for Lithium MnO_2 Systems in Military Applications

摘要

Saft is an industry leader in the development and manufacturing of both primary and rechargeable portable power solutions with a record of proven reliability across a wide range of applications. Saft has proudly served the United States warfighter providing the most comprehensive range of battery systems to deliver power capability for every mission. Saft continues to offer the ability to deliver solutions in all field proven primary chemistries including Lithium Sulfur Dioxide, Lithium MnO_2, and Lithium Thionyl Chloride, and now Lithium MnO_2/CF_x. Saft's LiMnO_2 program has delivered over the last 10 years proven battery designs to meet the requirements of the MIL-PRF 49471B and now the MIL-PRF 32271 specifications. Over this time Saft's has incorporated the Lithium Manganese Dioxide and more recently the Mixed Oxide (combining MnO_2 and CF_x cathode materials) battery technology into multiple battery systems and demonstrated the ability to meet and exceed the requirements of the military. Saft America continues to develop new cell designs with the aim of increasing overall energy densities while delivering a chemistry platform capable of meeting the robust performance and safety requirements for the military. This paper presents the latest results in cell designs to increase the capacity and energy densities and compares against currently available LiMnO_2 and Mixed Oxide systems.
