When the temperature of the cell is 130℃.

Cell must not fire or explode in 30 minutes

 

 

The cell is charged following the standard charge method. After charging the cell is put in the oven. And then the oven temperature will be ramped at

5℃ per minute to 130℃ and held at 130℃. When the temperature of the

cell reach 130℃, the cell is maintained in the 130℃ oven for a maximum of 30 minutes or until a fire or explosion is obtained, whichever comes

first. Record the time that the cell temperature reaches 130℃ and the time when a fire or explosion occurs.
