Multiple Hydrogen‐Bond Cross‐Linking Solid–Solid Phase Change Materials for Batteries’ Thermal Management

ABSTRACT Solid–solid phase change materials usually suffer from the challenges of low thermal storage capacity and poor mechanical strength in thermal management applications. Additionally, solid–solid phase change materials are often prepared by a chemical cross‐linking strategy, leading to poor recyclability. This study highlights a straightforward and effective strategy to prepare multiple H‐bonding cross‐linking supramolecular solid–solid phase change materials integrating easy recyclability, high mechanical strength, and high latent heat characteristics for thermal management of lithium batteries.
