The progress of the shirt circuit test (LTO-40AH)
The series of photos shows the progress of the short circuit test for the LTO-40Ah cell. At the beginning of the test, the temperature of the cells is same as the temperature of the surrounding, so that the cell is not visible at the IR photo.
Starting the tests, the temperature begins increasing and it is visible how the temperature rises from one side of the cell. The explanation is that the resistance of the terminals is not the same, and the terminal with a slightly higher resistance will cause the heating first.
During the test the temperature grow gradually from some 22°C to 48°C, up to some 80~90°C degrees.
Yes, the LTO chemistry is a fully safe battery technology even during a direct short circuit.
