Boron Doped Graphene Quantum Structure and MoS(2) Nanohybrid as Anode Materials for Highly Reversible Lithium Storage

Herein, the boron-doped graphene quantum structure (BGQS), which contains both the advantages of 0-D graphene quantum dot and 2-D reduced graphene oxide, has been fabricated by top-down hydrothermal method and then mixed with molybdenum sulfide (MoS(2)) to serve as an active electrode material for t...

description Herein, the boron-doped graphene quantum structure (BGQS), which contains both the advantages of 0-D graphene quantum dot and 2-D reduced graphene oxide, has been fabricated by top-down hydrothermal method and then mixed with molybdenum sulfide (MoS(2)) to serve as an active electrode material for the enhanced electrochemical performance of lithium ion battery. Results show that 30 wt% of BGQS/MoS(2) nanohybrid delivers the superior electrochemical performance in comparison with other BGQS/MoS(2) and bare components. A highly reversible capacity of 3,055 mAh g(−1) at a current density of 50 mA g(−1) is achieved for the initial discharge and a high reversible capacity of 1,041 mAh g(−1) is obtained at 100 mA g(−1) after 50 cycles. The improved electrochemical performance in BGQS/MoS(2) nanohybrid is attributed to the well exfoliated MoS(2) structures and the presence of BGQS, which can provide the vitally nano-dimensional contact for the enhanced electrochemical performance. Results obtained in this study clearly demonstrate that BGQS/MoS(2) is a promising material for lithium ion battery and can open a pathway to fabricate novel 2-D nanosheeted nanocomposites for highly reversible Li storage application.
