Abstract: By locating elemental Sn in an open anionic framework, the particle cracking arising from huge volume expansion of Sn-based anode materials during lithiation/delithiation is alleviated, and the cycling stability is greatly improved. The Sn-based metal-organic framework anode material shows superior cyclic stability, with a capacity retention >92 % (after 200 cycles) and high lithium storage capacity (610 mAh g <superscript>-1</superscript> ).<br /> (© 2018 Wiley-VCH Verlag GmbH & Co.
