While Rare, why do Batteries sometimes Catch Fire and Explode?

While rare, why do batteries sometimes catch fire and explode?
3D microtomography experiments at the Advanced Light Source enabled researchers to pinpoint which particles generated current densities as high as 25 milliamps per centimeter squared inside a resting battery after fast charging. In comparison, the current density required to charge the test battery in 10 minutes was 18 milliamps per centimeter squared. Credit: Nitash Balsara and Alec S. Ho/Berkeley Lab

How likely would an electric vehicle battery self-combust and explode? The chances of that happening are actually pretty slim: Some analysts say that gasoline vehicles are nearly 30 times more likely to catch fire than electric vehicles...

UCSD engineers have developed a breakthrough in electrolyte chemistry that enables lithium batteries to run at temperatures as low as -60C with excellent performance—in comparison, today’s lithium-ion batteries stop working at -20 degrees Celsius. The new electrolytes also enable electrochemical capacitors to run as low as -80C—their current low temperature limit is -40 degrees Celsius. While the technology enables extreme low temperature operation, high performance at room temperature is still maintained...
