Electrochemical properties and morphological evolution of pitaya-like Sb@C microspheres as high-performance anode for sodium ion batteries

Pitaya-like Sb@C microspheres are prepared successfully via a facile aerosol spray drying method, which present a high initial capacity, good capacity retention and high rate capability for Na-ion storage. Morphological evolution reveals that the maintenance of the pitaya-like configuration guarante... View More
