Advanced Thermal Interface Materials: Insights into Low-Temperature Sintering and High Thermal Conductivity of MgO.

ABSTRACT: The escalating frequency of electric vehicle (EV) fires has underscored the critical importance of effective thermal-management in battery package (TMBP). A key challenge in current TMBP lies with the low thermal conductivity (TC, 3 W m^-1 K^-1) of commercial alumina-polymer composite (thermal interface materials, TIM). While magnesia (MgO) TIMs, which show high TC (8-10 W m^-1 K^-1, this study) and low cost, are emerging as an alternative heat-dissipation material (HDM), their full potential remains untapped. Here, the development of novel MgO (≥ 80 W m^-1 K^-1) and MgO TIMs is presented as next-generation HDMs, designed to outperform conventional alumina (20-30 W m^-1 K^-1) and alumina TIMs. Crucially, the fu
