Lithium-Ion Cell ARC Thermal Runaway Test

This simulator places a single lithium-ion cell inside a virtual Accelerating Rate Calorimeter and drives it through a real three-stage Arrhenius kinetic cascade — SEI-layer decomposition, the dominant anode-electrolyte exotherm, and cathode/separator collapse — each stage consuming its own reactant fraction and releasing heat that feeds back into the cell's temperature. Tune state of charge, chamber heating rate and heat-rejection coefficient, or fire an internal-short pulse to simulate a nail-penetration trigger, and watch the cell's surface color and a live self-heating-rate trace carry it from a stable baseline through the T1 self-heating onset and T2 thermal-runaway trigger to a T3 peak, exactly the three landmark temperatures a real ARC report calls out.
