Measuring outgassing can prevent thermal runaway of batteries

<p>A battery, before undergoing <a class="wikilink" href="/thermal_runaway/">Thermal Runaway</a>, may release specific gases to the environment. There is a chance that by doing proper <a class="wikilink" href="/gas_sensing/">gas sensing</a> in the vicinity of a battery, it would be possible to detect a thermal runaway before it happens and act on it. </p> <p>As far as I know, the runaway happens very fast (in the range of the milliseconds) and that is why monitoring the temperature is not a good enough approach to preventing it (once the temperature raises, the runaway is in progress).</p>
