Molecular Engineering of Poly(3‐Alkylthiophene)s with Enhanced Positive Temperature Coefficient Effects for Intrinsically Safe Lithium‐Ion Batteries

-based temperature-sensitive electrodes (LFP-P3ATs) effectively shut down the electrode reactions at 110 °C, showing reliable temperature-sensitive characteristics. These findings establish molecular design principles for next-generation smart battery materials with intrinsic thermal protection capabilities.
