Not All Batteries Are Created Equal – A Failure Analysis Overview of Cylindrical Batteries

How many batteries do you have in your “battery drawer” at home? How many different sizes of alkaline batteries do you have? How many cylindrical lithium-ion batteries do you have scattered around your home? If the batteries did not have any labels on them, could you tell them apart? In a battery failure analysis, it is common for the battery wrappers to be removed or burned off. This presentation will discuss methods of characterizing batteries that have been involved in a failure to determine what type they are and possible failure origins.
