摘要
近年来,水系锂离子电池具有功率高、环境污染小等优点而受到广泛关注。文章采用在碱性体系中稳定性较好的Li Fe PO4作为正极材料,石墨板为负极,组装锌锂离子电池;通过SEM分析、XRD分析、循环伏安测试、线性扫描伏安测试等手段研究了锂的嵌入脱出以及锌的沉积溶解反应的反应活性及正极材料的稳定性。
In recent years, aqueous lithium-ion batteries have been widely studied due to their advantages of high power, low environmental pollution, etc. In this paper, we use Li Fe PO4 which has better stability in alkali systems as a positive electrode, graphite plate as the negative electrode. The reactivity of the lithium insertion/extraction, zinc deposition/dissolution and the stability of positive electrode material were studied by SEM, XRD, cyclic voltammetry, linear sweep voltammetry and other methods.
