α-MnSe nanocubes were successfully prepared for the first time
by an effective hot injection synthesis strategy. This approach was
simple but robust and had been applied to the controllable synthesis
of different sizes and diverse morphologies of α-MnSe nanostructures.
The crystal phases, compositions, and microstructures of these nanostructures
had been systematically characterized with a series of techniques.
As a proof-of-concept application, the as-prepared α-MnSe nanocubes
were used as an anode material for a lithium ion battery, which exhibited
superior rate ability and ultralong cycle stability in half-cell and
full-cell tests. Importantly, the phase transition from α-MnSe
to β-MnSe during the electrochemical process was proved by ex
situ X-ray diffraction and selected area electron diffraction. The
excellent electrochemical performance of α-MnSe endowed its
potential as an anode material candidate for high performance lithium
storage.
