The electrochemical properties of Li/TEGDME/MoS_2 cells using multi-wall carbon nanotubes as a conducting agent

摘要

We investigated the first charge–discharge behavior and cycling propertyof Li batteries using MoS_2 electrodes with multi-wall carbon nanotubes MWNT) as a conducting agent. The MoS_2 electrode was prepared using MWNT as the conducting agent. The battery gave a high first discharge capacity of 140 mAhg~(-1) with a plateau potential region at 1.1 V. The Li/MoS_2 battery using MWNT showed a higher discharge capacity compared to acetylene black. After ten ycles of the battery using MWNT, the discharge capacity decreased to 120 mAhg~(-1), which corresponded to 30% of the first discharge capacity. Adding a carbon nanotube into the MoS_2 electrode improved the first discharge behavior, but did not affect the cycling property of the Li/MoS_2 cell.
