- Abstract
- We investigated the electrochemical properties of lithium/molybdenum sulfide(Li/MoS₂) using tetra (ethylene glycol) dimethyl ether(TEGDME) electrolyte. The Li/TEGDME/MoS₂ cell showed the first discharge capacity of 288mAhg-1. From the XRD, SEM results of the MoS₂ electrode in various cut-off voltage during charge-discharge process, MoS2 partly changed into Li₂S and Mo during discharge and Li₂S partly recovered into MoS₂ and Li during charge. Full charged MoS₂ electrode showed lump shape of big size, which might be related to agglomerate of MoS₂ particles. Therefore, the degradation might be related to decrease of active material for electrochemical reaction by agglomeration of MoS₂.
