Coral–like Ni2P@C derived from metal–organic frameworks with superior electrochemical performance for hybrid supercapacitors

Transition metal phosphides (TMPs), used in hybrid supercapacitors (HSCs) as battery–type electrodes, have gain tractions for balancing the requirements for both power and energy; however, their poor structural integrity, inferior conductivity and low porosity restrict the achievable performance. Developing an elaborate material architecture for electrodes that endows mechanical robustness, superior conductivity and large surface area is a...
