英文摘要 | Manganese phosphate (Mn-3(PO4)(2)center dot 3H(2)O) nanosheets are successfully fabricated via a facile chemical precipitation method. The Mn-3(PO4)(2)center dot 3H(2)O nanosheets synthesized at 70 A degrees C show excellent supercapacitive performance in 2 M KOH alkaline electrolyte. Typical pseudocapacitance feature of Mn-3(PO4)(2)center dot 3H(2)O nanosheets treated at various annealing temperatures is then evaluated in 2 M KOH alkaline electrolyte. M-3 annealed at 750 A degrees C exhibits the optimal integrated electrochemical properties. Furthermore, an asymmetric supercapacitor composed of M-3 as positive electrode and activated carbon (AC) as negative electrode can reach the high-voltage region of 0-1.7 V. The asymmetric supercapacitor displays high energy density of 32.32 Wh kg(-1) and power density of 4250 W kg(-1). The impressive results presented here may pave the way for promising applications in high energy density storage systems. |
