LiFePO4 Cell Test Data - abuse and extreme conditions
The abuse test data show the results of hazardous situations and lithium cell extreme conditions: Overcharge by 1C and 2C current, overdischarge test by 0.5C current, cell damage – short Circuit, cell crush Test (50% of the cell), nail penetration test (3 mm), high temperature (150*C and 175*C), temperature performance, cycle life (0.5C).

These tests show that the LiFePO4 technology is really safe and can be used without worries about the danagers.
