Abstract:
To facilitate construction analysis, failure
analysis, and research in lithium–ion battery technology, a
high quality methodology for battery disassembly is needed.
This paper presents a methodology for battery disassembly
that considers key factors based on the nature and
purpose of post-disassembly analysis. The methodology
involves upfront consideration of analysis paths that will be
conducted on the exposed internal components to preserve
the state (operational or failed) of the battery. The disassembly
processes and exposures must not alter the battery
materials once they are removed from their hermetically
sealed containers. Because the process of battery disassembly
can involve exposure to potentially hazardous
compounds or lead to thermal run-away, a brief review
concerning the safety hazards of disassembly is also given.
