Abstract

Poly-acrylonitrile (PAN)-derived carbon fibres were characterised as air electrode frameworks for aqueous-alkaline metal-air batteries, focussing on the influence of the carbonisation temperature on the structure and electrochemical properties. Elemental composition, (atomic) structure, electrical conductivity, and electrochemical performance related to the oxygen reduction were investigated for electrodes carbonised in the range from 300 °C to 1400 °C. Chemical and structural properties were analysed using elemental analysis, XPS, SEM, and Raman spectroscopy; electrical conductivities of the fibre networks were examined by four-point probe measurements. Electrochemical properties were evaluated using linear sweep voltammetry in 6 M KOH by the open circuit potentials, the cathodic current densities at given overpotentials, and required overpotentials at given current densities. The highest current density was obtained from fibres carbonised at 850 °C. The connection between the fibre characteristics and electrochemical properties are discussed, highlighting the importance of the nitrogen bonding state. The results provide a base for thedevelopment of high performance air electrodes.

摘要

聚丙烯腈（PAN）基碳纤维被表征为用于碱性水系金属空气电池的空气电极框架，重点研究了碳化温度对结构和电化学性能的影响。对在300℃至1400℃范围内碳化的电极，研究了其元素组成、（原子）结构、电导率以及与氧还原相关的电化学性能。使用元素分析、X射线光电子能谱（XPS）、扫描电子显微镜（SEM）和拉曼光谱分析化学和结构性质；通过四点探针测量来检测纤维网络的电导率。在6M氢氧化钾溶液中，使用线性扫描伏安法通过开路电位、给定过电位下的阴极电流密度以及给定电流密度下所需的过电位来评估电化学性能。从在850℃碳化的纤维中获得了最高电流密度。讨论了纤维特性与电化学性能之间的联系，突出了氮键合状态的重要性。这些结果为高性能空气电极的开发奠定了基础。
