氮气电感耦合等离子体处理提升Ni-Al LDH电极材料性能
Nitrogen inductively coupled plasma treatment to enhance the performance of Ni-Al LDH electrode materials
等离子体处理材料是一种快速、有效提升电极性能的手段。首先用水热法在泡沫镍表面,于140℃、12 h的条件下合成了具有3D花簇状纳米片结构的NiAl-LDH,该电极在2 A/g时具有2 899.6 F/g的高比容量。随后使用氮气电感耦合等离子体装置在20 W和40 W的条件下处理该电极120 s。测试表明,氮气等离子体处理在电极表面成功实现了氮掺杂并引入了氧空位,在同样扫描速率下,处理后的电极比容量依次升高为3 063.6 F/g和3 320.8 F/g,性能依次提升了164 F/g和421.2 F/g。
Plasma treatment of materials is a fast and effective approach to enhance the performance of electrodes.NiAl-LDH with 3D flower cluster-like nanosheet structure was first synthesized by hydrothermal method on the surface of nickel foam at 140℃ for 12 h.The electrode had a high specific capacity of 2 899.6 F/g at 2 A/g.The electrode was subsequently treated using a nitrogen inductively coupled plasma device at 20 W and 40 W for 120 s.The results showed that the nitrogen plasma treatment achieved nitrogen doping on the electrode surface and introduced oxygen vacancies,and the specific capacities of the treated electrodes were increased to 3 063.6 F/g and 3 320.8 F/g at the same scan rate,and the performances were sequentially enhanced by 164 F/g and 421.2 F/g.
