Bimetallic transition-metal selenides have emerged as promising anode materials for lithium-ion batteries (LIBs). However, they suffer from rapid capacity fading which is originated from significant chemical and mechanical degradation during lithiation/delithiation processes. Herein, nitrogen-doped graphene aerogel (NGA) with high porosity is prepared via a templated method and serves as the matrix for the uniform growth of sheet-like binary transition-metal selenides (MoSe2–CoSe2). The porous NGA with high specific surface area provides a stable and conductive network, which can accelerate electron transmission and shorten the diffusion distance of Li ions. Furthermore, the MoSe2–CoSe2 nanosheets can offer adequate specific capacity because of its high accessibility and multiple redox properties. As a result, the MoSe2–CoSe2/NGA-10 composite delivers high Li-ion storage capacity (1260 mAh g−1 at 0.1 A g−1), excellent rate capability (702 mAh g−1 at 5 A g−1), and stable cycling performance (914 mAh g−1 at 1 A g−1 after 200 cycles), demonstrating its great potential for LIB applications.
