Discussion

Novel approach facilitates high thermal conductivity in phase change materials, enhancing thermal management efficiency.

The novel strategy results in PCCs with thermal conductivity of 8.7–44.7 W m−1 K−1, significantly improving thermal management efficiency.
Alignment of graphite sheets reduces thermal resistance, allowing for better thermal performance compared to traditional methods.
The experimental PCC device demonstrates a peak cooling power reduction of approximately 35%, indicating promising thermal storage capabilities.
These PCCs exhibit superior thermal effusivity and mechanical stability, making them suitable for diverse heat-related applications.

Wu et al. (2025) studied this question.
