<p>Metal organic frameworks (MOFs) hold great promise as high-energy anode materials for next-generation lithium ion batteries (LIBs) due to their tuneable pore structure and abundant reaction sites. However, since the pore structure of crystalline MOFs tends to collapse during lithium ion insertion and extraction, it has been a challenge to develop crystalline MOF-based anodes for high performance lithium ion batteries. Here we report a breakthrough in developing the high-performance MOF anodes. In detail, we have developed the first MOF glass anode, i.e., melt-quenched Cobalt-ZIF-62 glass anode with exceptional electrochemical performances. Compared with its crystalline counterpart, the Co-ZIF-62 glass anode exhibits significantly higher lithium storage capacity (306 mAh g<sup>-1</sup> after 1000 cycles at the current density of 2 A g<sup>-1</sup>), outstanding cycling stability and superior rate performance. Amazingly, the Li-ion storage capacity of the MOF glass anode continuously rises with increasing the number of charge-discharge cycles and even <i>tripled</i> after 1000 cycles. We revealed the possible origin of the unusual cycling-enhanced performances of the MOF glass anode. These superior performances make MOF glasses ideal candidates for anode materials for LIBs. </p>

Lithium-ion batteries (LIBs) have become commercialized technologies for the modern and future world, but commercial batteries using graphite still have a low specific capacity and are concerned with safety issues. Silicon (Si) and antimony (Sb) nanocomposites have the tendency to be synthesized as high-energy-density anode materials which can be a solution for the above-mentioned problems. This work reported the synthesis methods and characterization of Sb and Si composited with nitrogen-doped graphene (SbSi/NrGO) by facile chemical method and thermal treatment. Si was obtained by magnesiothermic reduction of SiO2 derived from rice husk, waste from the agricultural process. To study the phases, particle distributions, and morphologies, all prepared composites were characterized. In this experiment, the phase compositions were confirmed as [Formula: see text]-Si, [Formula: see text]-Si, SiC, Sb, and shifted peaks of expanded C which were caused by NrGO synthesis. Interestingly, a good distribution of Si and Sb particles on the NrGO surface was obtained in 15Sb15Si/NrGO composition. It could be due to appropriate Sb and Si contents on the NrGO surface area in composite materials. Morphological identification of synthesized products represented the Sb and Si particles in nanoscale dispersed on thin wrinkled-paper NrGO. These results suggested that the synthesis method in this paper is appropriate to prepare SbSi/NrGO nanocomposites to be used as high-performance anode materials in high-performance LIBs for advanced applications.
