Conducting Salts Govern Thermal Boundary Conductance across Solid Electrode/Organic Liquid Electrolyte Interfaces in Lithium-Ion Batteries.

ABSTRACT: Thermal boundary resistance at material interfaces poses a major challenge to effective heat dissipation in lithium-ion batteries, particularly at the interface between solid electrodes and organic liquid-based electrolytes. Despite its critical role in thermal management, the nanoscale mechanisms governing interfacial heat transfer in these systems remain poorly understood. Here, we employ all-atom molecular dynamics simulations to investigate heat transport across the interface between lithium cobalt oxide (LCO) electrodes and a liquid electrolyte mixture of ethylene carbonate and ethyl methyl carbonate (3:7 mass ratio) containing either LiPF₆ or LiTFSI salts at concentrations ranging from 0.05 to 2 M. Our results show that thermal boundary conductance is highly sensitive to b
