The transport and thermal properties of glassy LiPO3/crystalline Al2O3 (ZrO2) composite electrolytes

Understanding the thermal properties of amorphous solids using machine-learning-based interatomic potentials

“…Window glasses are one familiar example: their thermal expansion, thermal-shock resistance and thermal conductivity are all intimately connected with their atomic-level structure [20][21][22], and thus with their vibrational properties. Another important example is given by glassy Li-ion batteries, where the electronic contribution to the thermal conductivity is often non-negligible, and the thermal stability of the material heavily influences device performance [23][24][25][26][27]. How heat is conducted and dissipated through an amorphous matrix is also of great relevance in the context of data storage, as the new generations of non-volatile memories based on phase-change processes deal with active volumes only a few nanometres switched by voltage-induced heat pulses [28,30,31]; we will re-visit this exciting class of materials below.…”
