Effect of thermal impact on the onset and propagation of thermal
For cylindrical or plate heaters, the standards only provide maximum heater power associated with the cell energy, and their values vary in a large range. This is very different from mature ignition and fire tests, which define a minimum or fixed heat flux received by the fuel rather than giving a vague value of some heater power [39]. The lack
