HOST:    Have you ever wondered why batteries catch fire?  On this week’s Energy Bite, Venkat Viswanathan, a professor at Carnegie Mellon University, has some answers.

VENKAT: The batteries in the news for catching fire are Lithium Ion batteries.  These batteries are in many of the electronic devices we use including laptop computers, electric vehicles, and hover boards.  Lithium ion batteries are safe when they are in environments with air temperatures ranging from 14 to 104 degrees Fahrenheit.  The problem occurs when the battery is in very cold or very hot environments outside of this range.

HOST:     How can these battery fires be avoided?

VENKAT:  First, think about temperature when you are using a device with a lithium ion battery.  Second, only purchase batteries with a failsafe mechanism from a high quality manufacturer, and use the recommended chargers for that battery. Don’t use batteries or chargers from “aftermarket” manufacturers producing lower quality inconsistent batteries. Third, consider using devices powered by nickel-metal hybrid batteries instead of lithium ion.
