Abstract
The mesoporous texture carbon (meso-C) was prepared via a simple carbonizing of MOFs, and selenium was confined in meso-C by a facile melt-diffusion route to obtain meso-C@Se composite, the Se was well-distributed in meso-C@Se composite. The meso-C@Se composite cathode exhibits a good cycling performance and high rate capability. Meso-C@Se composite cathode displays an initial discharge capacity of 641 mAh g−1 and a reversible capacity of 306.9 mAh g−1 after 100 cycles at a current density of 337.5  mA g−1 (0.5 C). Meso-C@Se composite cathode has smaller resistance and better cycle performance than pristine Se cathode, and these test results indicate that the meso-C@Se composite is a promising host material for the cathode in the lithium selenium battery applications.
