摘要
随着锂离子电池的广泛使用,锂资源的短缺及分布不均等问题日益显著,导致锂矿石资源的价格不断上升,锂离子电池的成本不断增加,寻找锂离子电池替代品势在必行。钠离子电池因其具有资源丰富、价格低廉、环境友好等优点,有望替代锂离子电池成为下一代电动汽车及大规模储能电网电源的理想选择。因此,探索高比容量和具有优异循环性能的储钠电极材料已经成为目前电池领域的研究热点。本文以石油沥青为原料,在对甲苯磺酸等质子酸催化下,与对苯二甲醇、苯甲醛、三聚甲醛等交联剂经亲电取代反应可控合成不同三维结构的缩合多环多核芳烃(COPNA)树脂。以COPNA树脂为碳源,无机盐、金属氧化物等为模板,制备具有层次孔结构的硬碳材料,并将其用作钠离子电池负极材料。采用傅立叶转换红外线光谱(FTIR)、X射线衍射(XRD)、拉曼光谱(Raman)等技术手段,解析COPNA树脂的分子结构与其电化学性能之间的内在关系,为高性能钠离子电池的研发提供理论依据。
With the widespread use of lithium-ion batteries, the shortage and uneven distribution of lithium resources are becoming increasingly serious, resulting in continuously rising prices of lithium ore and lithium-ion batteries. It is imperative to look for an alternative of lithium-ion batteries. Sodium-ion batteries are expected to be a promising alternative to lithium-ion batteries for electric vehicle and large-scale electric grid power storage, due to their advantages of low cost, abundance and environmentally friendly. Therefore, exploring electrode materials with high capacity and excellent cycling performance has become research hotspot in energy storage. Thereby, petroleum asphalt was used as raw material to synthesize condensed poly-nuclear aromatic(COPNA) resin via the electrophilic substitution reaction with the catalysis of p-toluenesulfonic acid(PTS) and cross-linking agents of benzaldehyde, 1,4-benzenedimethanol(PXG) and s-Trioxane(TOX), using inorganic salt and metallic oxide as template to prepare hard carbon materials with hierarchical pore for sodium-ion batteries. The relationship between the structure of obtained COPNA resin and its electrochemical performance was investigated. This work can guide the development of sodium-ion batteries.
