- W4306785103 abstract "Energy storage materials are currently considered to promote the development of life and economy in a society with high energy consumption. Particularly, supercapacitors play a significant role in providing a sustainable human society as a kind of green energy storage system. Recently, most researchers mainly focus on improving the electrochemical properties of electrode materials. In light of cost-effective and discharged pollutants, eco-friendly and simple-operated synthesis is an advanced option to fabricate high-energy storage electrode materials. Herein, a green one-step strategy is introduced to prepare a series of A 3 (PO 4 ) 2 (A = Mn, Zn, and Co) hydrates at room temperature along with the characterization in terms of their phase structure, morphology, and electrochemical properties for potential high-performance supercapacitor electrodes. Interestingly, the Co 3 (PO 4 ) 2 ·8H 2 O electrode delivers a good specific capacity value of 210.67 mAh g −1 (specific capacitance value of 1516.8 F g −1 ) with a high voltage of 0.5 V under the current density of 1 A g −1 . Moreover, the constructed pouch-type device exhibits an outstanding cycling stability of ∼90.53% after the following 24000 cycles. In addition, the energy density of the fabricated device is estimated to be 33.44 Wh kg −1 while the maximum power density is found to be about 3750 W kg −1 . This work suggests that the A 3 (PO 4 ) 2 hydrates are very promising as excellent electrodes for supercapacitors with ultra-long cycling stability through a simple and green strategy. • A 3 (PO 4 ) 2 (A = Mn, Zn, and Co) hydrates were synthesized by a green route. • The crystal structure, morphology, and electrochemical properties were compared. • All the obtained samples have a large voltage of 0.5 V. • Co 3 (PO 4 ) 2 ∙8H 2 O electrode showed a good specific capacity of 210.67 mAh g −1 . • The pouch-type device showed excellent cycling stability and energy density." @default.
