Feasibility of a Super High Energy Density Battery of the Li/Br/F3 Electrochemical System
Abstract
Feasibility studies on the practical aspects of developing a lithium/ bromine trifluoride battery have been studied. Efforts directed toward identifying materials for porous electrode separators, glasses for insulated electrical feed-throughs, and metals for lid, case and current collector fabrication via electrochemical testing techniques have resulted in a list of materials suitable for these applications. Prototype cells utilizing a spirally wound electrode configuration have been constructed and discharged. The use of lithium salts as an electrolyte additive has been explored, and has shown a positive effect on discharge performance. Through the use of currently available technology, however, the lithium/bromine trifluoride couple has not delivered energy density comparable to other high energy density lithium systems. This investigation has revealed that practical Li/BrF3 cell development will require further extensive fundamental electrochemical research.
