This http://www.almaden.ibm.com/institute/2009/resources/2009/presentations/JeffDahn-AlmadenInstitute2009.pdf IBM paper compares some different battery technologies. On page 7 there are some graphs detailing the "problem" of temperature rises. Note that at about 250 ÂșC, there is an exponential rise in temperature. This could be due to a feedback mechanism in internal leakage, but perhaps it's also a sign of CF? The rise is most pronounced when Ni is included in the mix.
