在教室环境中演示了普通2032硬币电池形式的可充电3V锂离子电池的组装和测试，而无需使用昂贵和复杂的无空气设备。该程序旨在消除使用剧毒材料和易燃溶剂，可以在15分钟内完成，并被设计为尽可能便宜、安全和简单。这种电池可以通过廉价的USB充电器进行重复充电，也可以用来为LED茶蜡烛或类似设备供电。秒表和万用表可以用来估计电池的容量和电压。这个演示提供了一个令人难忘的、真实的电化学原理应用，并让学生对锂离子电池的化学和结构有了实际的见解。
The assembly and testing of a rechargeable 3 V lithium-ion battery in the common 2032 coin cell format is demonstrated in a classroom environment without the use of expensive and complex air-free equipment. The procedure has been developed to eliminate the use of highly toxic materials and flammable solvents, can be accomplished in 15 min, and is designed to be as inexpensive, safe, and simple as possible. The battery can be repeatedly charged with a cheap USB-powered charger and can be used to power an LED tea candle or similar device. A stopwatch and multimeter can be used to estimate the capacity and voltage of the battery. This demonstration offers a memorable, real-world application of electrochemical principles and gives students practical insight into the chemistry and construction of a lithium-ion battery.
