Abstract

Abstract

En 中文
• High-speed synchrotron radiography during Thermal Runaway of sodium-ion batteries. • Radial and axial projection enable complementary insights on TR mechanisms. • Nail penetration shows longer SIB cell TR durations compared to NMC LIB cells. • Fundamental SIB failure modes remain consistent across nail penetration speeds. • SIB safety critically depends on the configurations of integrated safety mechanisms.
