Abstract

Graphical abstract: Highlights: Amorphous ZnSnO3 double-shell hollow microcubes were synthesized. D-ZnSnO3 deliver better electrochemical properties than Y-ZnSnO3 . The amorphous feature and double-shell hollow structure improves the performance. Abstract: Amorphous ZnSnO3 double-shell and yolk-shell hollow microcubes were synthesized by calcination of their corresponding ZnSn(OH)6 precursors pre-prepared through a facile chemical solution method in argon. The as-prepared amorphous ZnSnO3 double-shell hollow microcubes have an average edge length of 1.6 μm. When used as the anode materials, amorphous ZnSnO3 double-shell hollow microcubes (D-ZnSnO3 ) reveal better electrochemical properties than ZnSnO3 yolk-shell counterparts (Y-ZnSnO3 ). D-ZnSnO3 anodes can retain a high reversible capacity of 741 mA h g −1 after 50 cycles with a coulombic efficiency of 99% at 100 mA g −1 . The amorphous feature and unique box-in-box hollow architecture of D-ZnSnO3 play a key role in their excellent electrochemical properties.
