Article Synopsis
- As the demand for powerful batteries increases, managing their heat becomes crucial for their performance and safety.
- Researchers found that composite electrodes made with multiwalled carbon nanotubes have significantly higher thermal conductivities—up to 141 W/mK in-plane—compared to traditional carbon black electrodes.
- The electrodes were created using a cost-effective filtration process and showed promising properties for high-performance applications, demonstrating their potential for improving thermal management in Li-ion and other high-density batteries.
We demonstrated experimentally that graphene-Cu-graphene heterogeneous films reveal strongly enhanced thermal conductivity as compared to the reference Cu and annealed Cu films. Chemical vapor deposition of a single atomic plane of graphene on both sides of 9 μm thick Cu films increases their thermal conductivity by up to 24% near room temperature. Interestingly, the observed improvement of thermal properties of graphene-Cu-graphene heterofilms results primarily from the changes in Cu morphology during graphene deposition rather than from graphene's action as an additional heat conducting channel.

We used graphene-like mechanical exfoliation of TiSe(2) crystals to prepare a set of films with different thicknesses. The transition temperature to the charge-density-wave state was determined via modification of Raman spectra of TiSe(2) films.
