摘要
A Ge-based metal-organic framework (MOF) precursor [C6H10(NH2)2Ge3O6] is used to fabricate two-dimensional GeO2 nanosheets in this work. The obtained micrometer-sized GeO2 nanosheet delivers superior lithium-storage capability during long cycling (an initial reversible capacity of 1315 mAh g− 1 at 100 mA g− 1 and the retained capacity of 1393 mAh g− 1 after 350 cycles). The observed large capacity and good cyclability have been mainly attributed to its nanosheet structure inherited from the MOF precursor, which can facilitate the electrolyte infusion and the lithium diffusion, maintain the structural stability, and alleviate the large volume change of the electrode during repetitive lithiation/delithiation process.
