β¦ Synopsis
The effects of some organic additives containing hetero-atoms on the charge-discharge characteristics of lithium have been investigated in propylene carbonate-or dimethylsulfoxide-based electrolytes. The addition of thiophene to propylene carbonate-based electrolytes improved the coulombic efficiency of the cycle, and the addition of pyrrole was effective for cycling in LiPFddimethylsulfoxide. The effect of the addition of 2methylfuran was significant in the solutions containing LiPF,. The a.c. impedance behavior at the electrode/electrolyte interphase suggested that the addition effects are related to changes in the interphase structure.
