Layered-structure MOF is a promising material for electrochemical energy storage applications. However, low conductivity hinders their electrochemical performance. Herein, a hierarchical layered-structure CoNi-MOF with ultrathin nanosheets and nanotube arrays are directly grown on carbon cloth (CC) with Co(OH)₂ as both template and Co source. The synthesized CC/CoNi-MOF shows high areal capacity of 1.01 C cm⁻² at 2 mA cm⁻², while keeps 61.4% capacity retention at 15 mA cm⁻². A hybrid supercapacitor is successfully fabricated with CC/CoNi-MOF as positive electrode and reduced graphene oxide-carbon nanotube as negative electrode, possessing a maximum areal capacitance of 846 mF cm⁻² at 1 mA cm⁻², a high energy density of 55.5 Wh kg⁻¹ at 175.5 W kg⁻¹, and excellent cycling stability (96.5% after 10000 cycles). This work may pave a new way for designing MOF based materials with similar structure for high performance supercapacitors.
