Novel Skutterudite CoP3–Based Asymmetric Supercapacitor with Super High Energy Density

Skutterudite CoP₃ holds a unique structural formation that exhibits much better electronic properties for obtaining high energy density supercapacitors. Herein, novel skutterudite Ni–CoP₃ nanosheets are constructed by etching and coprecipitating at room temperature and subsequent low‐temperature phosphorization reaction. Benefiting from the enhanced electrical conductivity and more electroactive sites brought about by adjusting the electronic structure with Ni incorporating the Ni–CoP₃ electrode with a battery‐type demonstrates an ultrahigh specific capacity of 0.7 mA h cm^?2 and exceptional cycling stability. The asymmetric supercapacitor (ASC) device fabricated by employing Ni–CoP₃ and activated carbon (AC) as positive and negative electrodes, resepectively, exhibits a remarkable high energy density of 89.6 Wh kg^?1 at 796 W kg^?1 and excellent stability of 93% after 10 000 cycles, due to the skutterudite structure. The skutterudite Ni–CoP₃ shows a great potential to be an excellent next‐generation electrode candidate for supercapacitors and other energy storage devices.

Na0.44MnO2颗粒尺寸对其作为水系钠离子电池正极性能的影响

水溶性钠离子电池是一种与锂离子电池相辅相成的技术,因其相对较低的成本、改善的安全性和环境友好的电解液而备受青睐。然而,较低的电极容量限制了这种电池的应用。Na_0.44MnO₂是一种用于钠离子电池的高容量阴极材料,其理论容量为121 mAh/g。文章研究了Na_0.44MnO₂的尺寸效应对阴极性能的影响。纳米棒通过热处理MnO₂纳米片前驱体制备而成,其尺寸通过CTAB和KMnO₄的比例进行调控。然后,Na_0.44MnO₂纳米棒被用作水溶性钠离子电池的活性材料。纳米棒阴极在1 C的初始循环中提供了60 mAh/g的容量,并在经过200个循环后保持了55 mAh/g,比Na_0.44MnO₂块状阴极高出37.5%。在高倍率的5 C下,该阴极在经过200个循环后仍能提供47 mAh/g的高容量。容量的增加归因于减小的电荷传递阻抗和纳米棒具有较高比表面积所带来的改善的钠离子扩散性能。
