“Grafting” NiSe onto Cu2-xSe with twinborn structure embedded in carbon-based nanofibers to weave freestanding sodium-ion storage electrode

Inspired by “grafting” in horticulture, we prepare a freestanding NiSe/Cu2-xSe@C@NCNFs electrode for Na+ storage, where the NiCu-MOF derived twinborn NiSe/Cu2-xSe heterostructure is protected by double carbon shells. It shows excellent cycle stability, after 100 cycles, the reversible specific capac...
