An integrated electrode based on nanoflakes of MoS 2 on carbon cloth for enhanced lithium storage

Due to its high specific capacity (in theory), molybdenum disulfide (MoS ) has been recognized as a plausible substitute in lithium-ion batteries (LIBs).

Zusammenfassung:Due to its high specific capacity (in theory), molybdenum disulfide (MoS ) has been recognized as a plausible substitute in lithium-ion batteries (LIBs). However, it suffers from an inferior electric conductivity and a substantial volume change during Li insertion/extraction. By using a facile hydrothermal method, a flexible free-standing MoS electrode has here been fabricated onto a carbon cloth substrate. The grafting of ultrathin MoS nanoflakes onto the carbon cloth framework (forming CC@MoS ), was shown to facilitate an improved electron transport, as well as an enhanced Li transport. As expected, the as-obtained CC@MoS electrode was observed to exhibit an excellent lithium storage performance. It delivers a high discharge specific capacity of 2.42 mA h cm at 0.7 mA cm (even after 100 cycles), which is an impressive result.
