The performance characteristics of the
normalLi/SOCl2
cell have been determined as a function of discharge rate, electrolyte composition, cathode thickness, and cell temperature. Cells have been discharged at rates ranging from about 3 to nearly 300 mA/cm2. Cathodes with electrolyte solutions have contained either
LiAlCl4
or
AlCl3
, with the most efficient discharge characteristics being realized with
1.5MLiAlCl4
and
4.5MAlCl3
solutions. The use of pure
AlCl3
dissolved in
SOCl2
as the electrolyte results in substantially higher average discharge voltages and discharge capacities than can be achieved with cells containing the conventional
LiAlCl4
electrolyte. With both electrolytes, however, the discharge capacity per unit cathode volume (the effective cathode utilization) decreases with increasing cathode thickness, the rate of decrease being greater the higher the discharge current density. Increasing cell temperature results in an improvement in cathode utilization and a decrease in overvoltage, again with both
LiAlCl4
and
AlCl3
electrolyte solutions.
Die Kennwerte der Li/SOCIQ‐ Zelle werden in Abhängigkeit von der Entladungsgeschwindigkeit, der Elektrolytzusammensetzung, der Kathodendicke und der Zellentemp.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
