Exploring the Science Behind Li-Ion Batteries and Coin Cell Assembly

At our exhibit, visitors will get an experience exploring the fundamental workings of lithium-ion (Li-ion) batteries and the intricate process of assembling a coin cell battery. Through interactive demonstrations and engaging explanations, we will break down the essential components of a Li-ion battery, explaining how they store and release energy to power everyday devices. Understanding Li-Ion Battery Mechanism: Visitors will learn about the key components of a Li-ion battery, including the cathode, anode, electrolyte, and separator. Using simple animations and hands-on models, we will illustrate the movement of lithium ions (Li⁺) and electrons during the charging and discharging process. A real-time demonstration will showcase how chemical energy is converted into electrical energy, effectively powering small devices. This interactive approach will provide a clear understanding of how Li-ion batteries function and their significance in modern technology. Coin Cell Assembly Demonstration: Attendees will also have the opportunity to observe the step-by-step assembly of a coin cell battery, similar to those used in watches and small electronics. We will explain the role of each layer, from the current collectors to the electrolyte-soaked separator, highlighting their importance in ensuring efficient battery performance. Participants will see firsthand how precision and safety play a crucial role in assembling a functional battery, deepening their appreciation for battery technology and its real-world applications.
