摘要

zno纳米片结构均匀、结构完善，具有优异的超级电容性能。独特的宽面纳米片提供了出色的电化学超级电容器性能。结果表明，该催化剂在电流密度为1 a /g时的比电容为700 F/g。有趣的是，该材料还表现出出色的循环稳定性，即使在5000次循环后也只损失2.75%。该研究证实，znco2o4基材料由于其优异的形貌、宽切面、出色的稳定性和电容，可以应用于高能量和高功率密度的应用(储能、电动汽车和柔性电子设备)。

Wide Facets ZnCo₂O₄ Nanosheets for High Electrochemical Supercapacitor Performances

ZnCo 2 O 4 nanosheets show excellent supercapacitive performance due to their well-developed and uniform architecture. The unique nanosheets with wide facets deliver outstanding electrochemical supercapacitor performance. As a result, the catalyst exhibits a specific capacitance of 700 F/g at a current density of 1 A/g. Interestingly, the material also shows outstanding cycling stability and loses only 2.75% even after 5000 cycles. The study confirms that ZnCo 2 O 4 based materials can be applied in high-energy as well as high-power density applications (energy storage, electric vehicles, and flexible electronic devices) due to their excellent morphology, wide facets, outstanding stability, and capacitance.
