Effects of Compaction Density on the Electrochemical Performance for Li-S Batteries
摘要
In order to study the effects of compaction density on the electrochemical performance of lithium-sulfur (Li-S) batteries, this study prepares the sulfur electrodes with various pressure. The structure of these samples with distinct compaction densities is characterized by scanning electronic microscopy (SEM). Moreover, the electrochemical performance of the samples is conducted. The results show that proper compaction density positively affects Li-S batteries’ coulombic efficiency and cycling performance. Meanwhile, in pursuit of practical applications for Li-S batteries, this work provides several meaningful suggestions.
