Safety
Thermal Propagation Test: Validated Safety at the Module Level
The thermal propagation test examines how a thermal event involving a single lithium-ion cell spreads within a battery module. To do this, a cell is deliberately triggered to enter "thermal runaway"—a state in which the cell releases its stored energy in an uncontrolled manner.
In a side-by-side comparison, the reference cell exhibits the full progression of thermal runaway. In contrast, our immersion-cooled Lili battery module confines this event to the affected cell: heat is immediately dissipated via the cooling medium, preventing neighboring cells from heating up to critical levels.
The result: The integrated pressure relief valve opens in a controlled manner to relieve pressure. There is no thermal propagation to other cells, no visible flame formation, and no module explosion.
Passing this test validates our module’s safety concept: immersion cooling and targeted pressure relief effectively manage thermal loads, prevent the spread of a cell-level event, and safeguard the integrity of the battery module.
