Thermal runaway
Under certain conditions, some battery chemistries are at risk of thermal runaway, leading to cell rupture or combustion. As thermal runaway is determined not only by cell chemistry but also cell size, cell design and charge, only the worst-case values are reflected here.{{cite journal|last1=Doughty|first1=Dan|last2=Roth|first2=E.
