“…In recent years, substantial efforts have been made to develop the new anodes with high power/energy density and superior cycling life for LIBs. Metal selenides, such as MoSe 2 , [1][2] CoSe x , [3][4] WSe 2 , [5] SnSe 2 [6][7] and GeSe 2 , [8][9] have received much attention owing to their rich redox chemistry, high specific capacities and better electrical conductivity compared to their oxide counterparts. On the other hand, the weaker bonding of metal-selenium improves the reversibility of the conversion reaction during the charge and discharge process.…”

A composite of two-dimensional (2D) GeSe 2 nanosheets dispersed on N-doped reduced graphene oxide (GeSe 2 /N-rGO) is fabricated via a simple hydrothermal method combined with post-selenization process. The high electronic conductivity and the substantial void spaces of the wrinkled N-rGO can improve the electrical conductivity of the active material and accommodate the volume evolution of GeSe 2 nanosheets during the (de)lithiation processes, while GeSe 2 nanosheets can reduce ion diffusion length effectively. Meanwhile, the unique layered structure is beneficial to the contact of the active material and electrolyte, and the reversibility of conversion reaction has also been improved. Furthermore, kinetics analysis reveals a pseudocapacitance-dominated Li + -storage mechanism at high rates. In-situ X-ray diffraction analysis discloses that the conversion reaction has played a certain part in Li + -storage. Thus, the GeSe 2 /N-rGO composite delivers excellent rate capability and good long-term stability with a high reversible capacity of 711.0 mA h g À 1 after 2000 cycles at 1 A g À 1 .
