Abstract
THE KEY TO WIDESPREAD APPLICATION OF RECHARGEABLE LITHIUM CELLS IS AN ELECTROLYTE THAT DOES NOT UNDERGO REACTIONS LEADING TO CELL VENTING UNDER ALL LIKELY CONDITIONS OF CELL ABUSE (ELECTRICAL, MECHANICAL, OR THERMAL). THIS PROJECT WILL SYNTHESIZE A NUMBER OF NEW LITHIUM SALTS AND CHARACTERIZE THEIR PERFORMANCE AS ELECTROLYTES IN LI/TIS2 CELLS. CHARACTERIZATION WILL INCLUDE CONDUCTIVITY, STABILITY IN CONTACT WITH LITHIUM AND TIS2, AND EFFECTS ON THE CYCLING BEHAVIOR OF THE CELL. PROMISING ELECTROLYTES WILL BE FURTHER EVALUATED IN CYCLED LI/TIS2 CELLS AT TEMPERATURES ABOVE THE MELTING POINT OF LI.
