Thermal runaway

<p>One of the challenges of working with batteries is that they are undergoing a continuous chemical reaction process. From charging to releasing energy back to the system. The reaction should happen under controlled conditions (temperature, current, etc.) There is a chance that a battery can "short-circuit" internally, leading to an increase in temperature, which leads to more current, etc. </p> <p>Sometimes (but not always), this happens when the battery is damaged: that's why you should not move your seat at an airplane if you lose your phone. </p> <p>However, deterioration of batteries can also lead to thermal runaways. </p> <p>In any case, the situation will be the same: a chain reaction that can't be stopped, and temperatures reaching several hundreds of degrees, enough to start a fire. </p> <p>There is a fair chance that <a class="wikilink" href="/measuring_outgassing_can_prevent_thermal_runaway_of_batteries/">measuring outgassing can prevent thermal runaway of batteries</a></p>
