摘要
以LiFePO_(4)为正极、Zn箔为负极,以Li_(2)SO_(4)+ZnSO_(4)的饱和蔗糖溶液为电解液,利用自封袋、无纺布、不锈钢网等材料组装制备了软包装电池。通过循环伏安曲线、充放电曲线、LED灯测试等方法对电池性能进行了评估。该实验可操作性强且易重复,所用材料环境友好、安全性高、价格便宜,测试仪器简单,不需要干燥间或手套箱等复杂设备,学生在普通化学实验室就可以亲身体验软包装电池的制备流程,直观感受化学能与电能之间的转化,并深入理解氧化还原反应过程及储能电池工作原理。
A feasible experiment of preparing flexible packaging hybrid batteries with LiFePO_(4)as cathode material and Zn as anode material is designed.The saturated sucrose aqueous solution containing 1 mol/L Li_(2)SO_(4)+ZnSO_(4)is used as electrolyte.The stainless-steel mesh,non-woven membrane and self-sealing bag are also used.The batteries are evaluated by cyclic voltammetry curve,battery charge-discharge curve and LED lamp test.No organic solvents or toxic chemicals are required,nor is a severe drying laboratory or a glovebox.The experiment has strong operability and repeatability.The materials used are environmentally friendly,safe and cheap.This experimental design offers new routes to familiarize students with the construction and mechanism of lithium ion batteries.The real-world applications of electrochemistry are presented visually.
