The Future of EVs: As electric vehicle (EV) use increases worldwide, attention is turning to the crucial issue of battery safety. One major concern is the risk of thermal runaway—a dangerous chain reaction that can turn a single faulty battery cell into a serious fire hazard.
A Growing Challenge: While passenger EVs are mostly in the spotlight, electric buses present significant risks due to the number of passengers they carry. Managing thermal runaway is a top priority, but predicting when it will happen is nearly impossible. Whether during a drive, a crash, or a quiet charge at home, these events can arise unexpectedly.
Safety Incidents: Though incidents are rare, they do occur, sparking safety checks like the extensive examination of 400 buses in London after multiple battery fires in early 2024. This highlights the importance of developing more sophisticated safety measures for EVs.
Evolution of Battery Design: Engineers are continuously innovating to prevent thermal runaway from spreading. The integration of advanced materials has become pivotal. Current methods involve a variety of protective measures at both the cell and pack level, utilizing materials such as ceramics, foams, and aerogels. These materials must have low thermal conductivity and minimal weight to maintain efficiency.
Industrial Innovations: Companies like H.B. Fuller are at the forefront of developing safer battery materials. Their polyurethane foam encapsulants are designed to block thermal spread effectively. These materials undergo chemical changes under high heat to protect adjacent cells and prevent escalation.
The march towards safer and more efficient EVs continues, with cutting-edge materials and designs reshaping the future of mobility.
