For years, lithium-ion (Li-ion) batteries have been a favorite choice among engineers and designers to power consumer electronic devices. However, the act of charging and discharging a Li-ion battery produces changes in temperature, electrochemistry, and mechanics of its internal components. These dynamics also cause changes in interface pressure within the battery housing, and in extreme cases, result in dangerous thermal runaway reactions.
This webinar will cover a design story of an engineering team that utilize ultra-thin piezoresistive pressure sensing technologies to help characterize Li-ion battery dynamics. Not only did this core technology help them develop a safer battery design, but it also gave them the idea to create a sensor-driven application within the device to alert users to any unusual battery activity.
