Corrosion
Copper Corrosion Product
Heavy corrosion product at a main damage site, useful as a mechanism-first example rather than a generic residue photograph.
Interpretation
Why this image matters
The report concluded that the primary corrosion product involved copper corrosion and that the major constituents were most likely due to battery-cell electrolyte rather than a process contaminant.
That gives the image stronger teaching value than a generic residue example because both the chemistry and the location support a mechanism-focused interpretation.
It is especially useful for showing that severe corrosion aftermath can partially mask the initiating event, yet still provide strong evidence about the governing process.

Best comparison value
- Teaching corrosion product at a functionally relevant conductive site
- Comparing meaningful corrosion evidence to incidental residue
- Discussing chemistry-plus-location interpretation in failure analysis
