The electrochemical properties of Li/TEGDME/MoS2 cells using multi-wall carbon nanotubes as a conducting agent

We investigated the first charge–discharge behavior and cycling property of 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 440 ...

Description
Summary:We investigated the first charge–discharge behavior and cycling property of 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 440 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 cycles 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.
