Abstract: Addressing the challenges in teaching the Nernst equation in inorganic chemistry, this experiment introduces the cutting-edge zinc-air battery as a teaching model. By altering the concentration of oxidizing and reducing materials, students explore the key factors of the Nernst equation, enhancing their understanding of electrochemical processes. Simultaneously, the experiment incorporates flexible electronics technology, using carrageenan as a safe and environmentally friendly solid electrolyte to guide students in learning and constructing solid zinc-air batteries. The batteries are tested for voltage performance at various bending angles to assess their flexibility. Moreover, to foster creativity, students design and build various forms of solid zinc-air batteries to power electronic devices. This experiment is closely aligned with fundamental electrochemical knowledge and state-of-the-art technology, allowing students to deepen their understanding of the Nernst equation while gaining practical experience in creating flexible electronic devices. This approach sparks students’ interest in electrochemistry and proves cost-effective with promising results.
