Can anyone point me to a LiCo capacity vs cycles graph?

    Here's a 2006 data sheet of a Sanyo UR18650F (likely close to what the Roadster used). Last page has a 500 cycle degradation graph. The link is not directly from manufacturer, but the datasheet looks legit.

    According to the material datasheet here, the UR18650F series is a pure lithium cobalt cell (more modern cells tend to have a mix of lithium manganese or some kind of nickel based mix like NCA and NMC):

    Edit, I dug a bit and found a newer 2012 datasheet for the same model number (although maybe updated a bit) direct from the manufacturer:
