Tailored design of an oxygen-rich stable Co-MOF integrated with MXene nanofibers as an advanced heterostructure for high-performance ammonium-ion supercapacitors

Abstract

, retaining 87% of their capacitance after 16 000 cycles. This study highlights the synergistic advantages of integrating stable MOFs with MXene nanofibers for remarkable ammonium-ion storage. It establishes a framework for designing high-performance energy storage materials, paving the way for next-generation sustainable energy storage devices.
