Multifunctional and Flexible Phase Change Composites for Dual-Mode Thermal Management of Lithium-Ion Batteries.

ABSTRACT: Phase change materials (PCMs) are highly renowned for their substantial latent heat capacity, enabling efficient thermal management in applications such as buildings, wearable devices, and lithium-ion batteries (LIBs). However, conventional PCMs suffer from mechanical rigidity, leakage, and low thermal conductivity. In this study, multifunctional, flexible, and leakage-proof phase change composites (PCCs) are developed to overcome these limitations and enable dual-mode thermal regulation for all-climate LIBs. The PCCs provide Joule heating (22.5 °C min^-1) under subzero conditions to prevent lithium plating and restore capacity. Simultaneously, they deliver passive cooling to optimise the operating temperature of LIBs, acrosspower output scenarios (2C and 3C). The performance is
