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(2)) 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...

Sumario:Due to its high specific capacity (in theory), molybdenum disulfide (MoS(2)) 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(2) electrode has here been fabricated onto a carbon cloth substrate. The grafting of ultrathin MoS(2) nanoflakes onto the carbon cloth framework (forming CC@MoS(2)), was shown to facilitate an improved electron transport, as well as an enhanced Li(+) transport. As expected, the as-obtained CC@MoS(2) electrode was observed to exhibit an excellent lithium storage performance. It delivers a high discharge specific capacity of 2.42 mA h cm(−2) at 0.7 mA cm(−2) (even after 100 cycles), which is an impressive result.
