The researchers decided to explore using tower block games like Jenga to explain Li-ion battery operation because “The archetypal Li-ion battery with electrode materials LiCoO 2–graphite is a layered system, and hence, the stacking of blocks in a normal tower block game makes this traditional set ideal for customization into the appearance of this battery setup,” they write. “Although these are good hands-on activities to introduce key aspects of batteries, these demonstrations cannot explain how rechargeable batteries work and, additionally, often lead to a misconception that the lemon or the potato is the powerhouse behind the circuit.” “The most commonly used activity employs lemon-/potato-electrolyte batteries, which are useful for introducing the concept of electrode potentials, electrical circuits, and a non-rechargeable battery,” they write. In the paper’s introduction, the researchers explain their study grew from a desire to overcome some limitations inherent in current battery demonstrations. Jenga to the rescue: Modified tower block game aids understanding of rechargeable Li-ion batteries But how does one easily and clearly communicate Li-ion battery science to students who may have very little science background? In a new paper, a team of researchers from the University of Birmingham’s School of Chemistry offer a unique and fun approach. No wonder three scientists who helped develop the technology were awarded the Nobel Prize in Chemistry last year.īecause Li-ion batteries play such a big role in our everyday lives, this topic is important for students to understand.

Li-ion batteries are the foundation for most of today’s advanced electronics, from portable devices (like smartphones) to electric vehicles and renewable energy storage. Could Jenga help students understand how lithium-ion batteries work?
