In-situ-grown multidimensional Cu-doped CoS@MoS on N-doped carbon nanofibers as anode materials for high-performance alkali metal ion batteries.

Transition metal sulfides with the high theoretical capacity and low cost have been considered as advanced anode candidate for alkali metal ion batteries, but suffered from unsatisfactory electrical conductivity and huge volume expansion. Herein, a multidimensional structure Cu-doped CoS@MoS in-situ-grown on N-doped carbon nanofibers (denoted as Cu-CoS@MoS NCNFs) have been elaborately constructed for the first time. The bimetallic zeolitic imidazolate framework CuCo-ZIFs were encapsulated in the one-dimensional (1D) NCNFs through an electrospinning route and then on which the two-dimensional (2D) MoS nanosheets were in-situ grown via a hydrothermal process.

Highly uniform platanus fruit-like CuCoS microspheres as an electrode material for high performance lithium-ion batteries and supercapacitors.

Platanus fruit-like CuCoS microspheres were fabricated by using a facile hydrothermal method followed by a sulfidation process. As a lithium storage material, they deliver an outstanding initial specific capacity of 1119.3 mA h g at 0.
