    Failure analysis

    CALCE labs have a wide range of failure analysis resources which are used to investigate internal battery materials. A review on battery failure analysis and a method for conducting battery disassembly can be found in CALCE’s publication Disassembly Methodology for Conducting Failure Analysis on Lithium-Ion Batteries.
