Though carbon matrices could effectively improve the electrical conductivity and accommodate volume expansion of CuO-based anode materials for lithium ion batteries (LIBs), achieving an optimized utilization ratio active CuO component remains a big challenge. In this work, we developed metal-organic framework (MOF)-derived strategy to synthesize ultrafine nanoparticles embedded in porous matrix (CuO@C). Benefiting from its unique structure, resulting CuO@C exhibits high reversible capacity...
Binary metal oxides with high theoretical specific capacities and power densities are promising anode materials for lithium-ion batteries but their poor cycling stability huge volume expansion limit extensive application in practical electrode materials.
Precise control over the interlayer spacing for K+ intercalation is an effective approach to boost potassium-storage performances in carbonaceous materials. Herein, we first found that optimal around 0.38 nm N, O codoped carbon nanofibers (NOCNs), displaying a reversible capacity of 627 mAh g-1 at 0.1 A after 200 cycles, excellent rate capability (123 20 g-1), and ultrastable cycling stability (262 5 10 000 cycles). Such good have never been reported The theoretical calculations...
Developing earth-abundant and highly efficient nonprecious metal catalysts for hydrogen evolution reaction (HER) is critical the storage conversion of renewable energy sources. Molybdenum carbide (Mo2C) has been extensively investigated as one most promising electrocatalysts boosting HER because its low cost, high electrical conductivity, good chemical structure, similar electronic structure to that Pt. However, Mo2C always exhibits negative hydrogen-binding energy, which can largely prevent...
Although nickel sulfides with high theoretical capacities have been demonstrated as promising anodes for sodium/potassium ion batteries (SIBs/KIBs), they always suffer from large volume expansion and inferior electronic conductivity, resulting in irreversible capacity loss. In this work, we design prepare NiS nanosheets attached to the inner surface of hole nitrogen-doped carbon matrixes (h-NiS@N-C), which could provide much more exposed active sites electrochemical reactions SIBs KIBs. The...
The design and fabrication of low-cost, efficient, robust electrocatalysts for the hydrogen evolution reaction (HER) is great importance in accelerating development water electrolysis technology. Herein, NiRu alloy nanostructures embedded a nitrogen-doped carbon matrix (NiRu@NC) have been fabricated through facile metal-organic framework-derived (MOF-derived) strategy. Benefiting from their advantages unique structures components, resulting NiRu@NC possesses excellent activity durability...
The resulting NOPCP exhibited excellent electrochemical performance for long-term lithium and sodium storage.
Heteroatom-doped porous carbon materials have been widely used as anode for Li-ion and Na-ion batteries, however, improving the specific capacity long-term cycling stability of ion batteries remains a major challenge.
