Why Solid-State Batteries Resist Thermal Runaway — and Where They Can Still Fail
Solid-state batteries significantly mitigate thermal runaway by using non-flammable solid electrolytes, which suppress dendrites and remove fuel for chain reactions. However, residual risks from reactive electrodes and manufacturing defects mean they are not absolutely safe and require ongoing engineering.
