Development of Large Li-Ion Batteries for Aircraft and Spacecraft Applications
Abstract
This program was initially focussed on the development of very large rechargeable Li/SO2 cells for use as a survival pow source in missile silos. With the diminishment in the strategic value of these missile systems came a redirection of the program towards smaller cell silos. Concurrent was a chemical direction which changed the emphasis of the program from the rechargeable Li/SO2 chemistry to that of the family of cell chemistries which are collectively referred to as lithium ion. These cells are based on a metal oxide cathode, a carbon-lithium intercalation anode and an electrolyte solution consisting of a mixture of organic solvents and a soluble Li salt. These systems moved to the forefront of advanced battery technology in the early 1990s because they clearly offered significant improvements in cycle life, cell safely and energy density/specific energy. More recently, it became clear that spacecraft batteries based on large (20 to 100-Ah) Li ion cells would offer a significant reduction in spacecraft power system mass and the USAF Phillips laboratory joined Wright laboratory and Canada's DND in the sponsorship of this program.
