Abstract Composite phase‐change materials (CPCMs), with their substantial latent heat storage and release capabilities at a consistent transition temperature, are extensively employed in diverse thermal‐energy‐storage applications. However, the risk of thermal runaway remains significant challenge owing to flammability potential leakage CPCMs. Attempts develop flame‐retardant PCMs using various fireproof polymers through physical methods exist. In this study, novel multifunctional solid–solid material is developed chemical modification process, incorporating polyethylene glycol 2000, boric acid, phosphorus pentoxide (P 2 O 5 ), expanded graphite, ammonium polyphosphate (APP), melamine (MA). This composite exhibits superior flame retardancy stability, making it highly suitable for enhancing safety battery modules. Experimental results demonstrate that PCAM2, containing 20 wt% MA 8 APP, maintains 97.75% mass retention 250 °C h achieves V‐0 rating (burning stops within 10 s) according UL‐94 standard. Moreover, module PCAM2 demonstrated thermal‐management than three other Even after ten cycles 2C discharge rate, maintained peak operating temperature below 60 °C. Notably, CPCM films exhibited propagation time, indicating control ability inhibit runway.

Enhancing Thermal Protection in Lithium Batteries with Power Bank-Inspired Multi-Network Aerogel and Thermally Induced Flexible Composite Phase Change Material

Nano-Micro Letters, Journal Year: 2025, Volume and Issue: 17(1)

Published: Feb. 26, 2025

Abstract Thermal runaway (TR) is considered a significant safety hazard for lithium batteries, and thermal protection materials are crucial in mitigating this risk. However, current generally suffer from poor mechanical properties, flammability, leakage, rigid crystallization, they struggle to continuously block excess heat transfer propagation once saturation occurs. This study proposes novel type of material: an aerogel coupled composite phase change material (CPCM). The consists gelatin/sodium alginate (Ge/SA) biomass as insulating component thermally induced flexible CPCM made thermoplastic polyester elastomer heat-absorbing component. Inspired by power bank, we the with through binder, so that can continue ‘charge store energy’ aerogel, effectively absorbing heat, delaying phenomenon, maximizing duration insulation. results demonstrate Ge/SA exhibits excellent insulation (with temperature difference approximately 120 °C across 1 cm thickness) flame retardancy (achieving V-0 retardant rating). high storage density (811.9 J g −1 ), good flexibility (bendable above 40 °C), stability. Furthermore, Ge/SA-CPCM shows even more outstanding performance, top surface remaining at 89 after 100 min exposure 230 °C. provides new direction development TR batteries.
