During Week 3, the focus is on the safety risks associated with lithium-ion batteries, particularly examining the underlying phenomena related to electrical, thermal, and mechanical abuse. The week highlighted how these batteries can experience failures due to overcharging, short-circuiting, and exposure to extreme temperatures, leading to hazardous situations such as fires or explosions. Various mitigation technologies were explored, including enhanced battery management systems and thermal management innovations, aimed at reducing risks during operation. Additionally, strategies for risk minimization were emphasized, stressing the importance of robust design, rigorous testing, and adherence to safety standards to ensure the safe use of lithium-ion batteries across diverse applications. These discussions are crucial for advancing battery technology while prioritizing user safety.
