Room Temperature Resistive Hydrogen Sensor for Early Safety Warning of Li-Ion Batteries

Lithium-ion batteries (LIBs) have become one of the most competitive energy storage technologies. However, “thermal runaway” LIBs leads to serious safety issues. Early warning is a prerequisite for widely applications power battery and large-scale systems. As reported, hydrogen (H2) could be generated due reaction lithium metal polymers inside battery. The generation H2 some time earlier than runaway”. Therefore, rapid detection trace effective method early LIBs. Resistive sensors attracted attention in recent years. In addition, they placed LIB package initial detection. Here, we overview key advances resistive room temperature (RT) sensors, explore possible LIB. We explored underlying sensing mechanisms each type sensor. Additionally, highlight approaches develop large scale. Finally, present review presents brief conclusion perspectives about RT
