Wet-Chemical Processing of Phosphorus Composite Nanosheets for High-Rate and High-Capacity Lithium-Ion Batteries. Advanced Energy Materials, 6(10), 1502409-. | Series/Report no.: | Advanced Energy Materials | Abstract: | Phosphorus-based materials are promising for high-performance lithium-ion battery (LIB) applications due to their high theoretical specific capacity. Currently, the existing physical methods render great difficulty toward rational engineering on the nanostructural phosphorus or its composites, thus limiting its high-rate LIB applications. For the first time, a sublimation-induced synthesis of phosphorus-based composite nanosheets by a chemistry-based solvothermal reaction is reported. Its formation mechanism involves solid–vapor–solid transformation driven by continuous vaporization–condensation process, as well as subsequent bottom-up assembly growth. The proof-of-concept LIBs composed of the phosphorus-based nanosheets achieve a high capacity of 630 mAh g−1 at an ultrahigh current density of 20 A g−1, which is attributed to efficient lithium-ion diffusion and electron transfer. Such simple sublimation-induced transformation opens up new prospects for rational engineering of phosphorus-based materials for enhancing electrochemical performance. | URI: | https://hdl.handle.net/10356/85102 http://hdl.handle.net/10220/43619 |
