摘要:
A high-performance fiber-shaped electrode composed of hierarchical NiCo2O4@polypyrrole core-shell nanowires on hemp-derived carbon (HDC) microfiber is successfully fabricated, which takes advantage of the high electrical conductivity of polypyrrole and carbon microfiber to boost the pseudocapacitive performance. The as-synthesized electrode exhibits an ultrahigh specific capacitance of 2055 F g-1, excellent rate performance and outstanding cycling stability (90% capacity retention over 5000 cycles). Based on the good mechanical flexibility and ...
