Abstract

We investigated the first charge–discharge behavior and cycling property of Li batteries using MoS2 electrodes with multi-wall carbon nanotubes (MWNT) as a conducting agent. The MoS2 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/MoS2 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 MoS2 electrode improved the first discharge behavior, but did not affect the cycling property of the Li/MoS2 cell.
