Characteristics of Quallion's Lithium-Ion Cells for Aerospace Applications

摘要

Rechargeable batteries that are presently in use in space missions include: Silver-Zinc (Ag-Zn), Nickel-Cadmium (Ni-Cd), Nickel-Hydrogen (Ni-H2), and more recently, Lithium-Ion (Li-Ion) batteries. In space applications, Li-Ion batteries offer significant mass and volume advantages (three- to four-fold) compared to standard Ni-Cd and Ni-H2 batteries. To address this need, Quallion LLC has developed custom true prismatic Li Ion cells for use in Low Earth Orbit (LEO) & Geosynchronous Earth Orbit (GEO) applications: a 15Ah cell (QL015KA) and a 72Ah cell (QL07SKA). In addition to using Quallion's patented long life Li-Ion chemistry, these cells are also Zero-Volt™ enabled, allowing for battery recovery in loss of spacecraft attitude and lower maintenance before launching.
