Carbon coated copper sulfides nanosheets synthesized via directly sulfurizing Metal-Organic Frameworks for lithium batteries

• Carbon coated copper sulfides nanosheets synthesized via directly sulfurizing Metal-Organic Frameworks.
• Carbon coated copper sulfides nanosheets are test as cathode for lithium batteries.
• The as-prepared C@Cu1.96S nanosheets deliver promising electrochemical performance.

Carbon coated copper sulfides nanosheets, denoted as C@Cu1.96S, are successfully prepared via directly annealing Metal-Organic Framework (HKUST-1) and commercial sulfur powder. As cathode materials for lithium batteries, the as-prepared C@Cu1.96S nanosheets deliver high reversible capacity, good capacity retention and superior rate capability.
