Abstract: Li-ion battery electrodes are typically mixed with carbon black materials which have low thermal conductivity in high-power-density battery applications. In this study, multi-walled carbon nanotubes (MWCNTs) were added to Li-ion battery electrodes to improve thermal conductivity. A measured the thermal conductivity of the electrode samples at room temperature using the transient plane source (TPS) method. Results showed that the addition of MWCNTs enhanced the thermal conductivity of the electrodes by up to two orders of magnitude compared to the conventional mode of synthesis. The success of this research can be applied to the thermal management of commercial electrode-active products in the future.
