Exploring the Effect of Carbon Microstructure on Lithium-Ion Battery Performance

Combining Raman spectroscopy and analytical imaging to assess graphite crystallinity.

With the upsurge in use of portable electronic devices such as tablets and mobile phones, through to the development of environmentally-friendly electronically powered vehicles, we are experiencing an unprecedented demand for batteries. Developing new, more efficient and more powerful batteries has never been more relevant.

In a previous application note, we discussed the importance of controlling the size of particles used in the manufacture of battery materials. Shape is also an important factor to consider and control, as irregularly-shaped particles not only reduce packing density, but can lead to the formation of a high viscosity electrode slurry.

In this application note, we consider the impact on battery performance of the microstructure of the carbon used to manufacture graphite electrodes, and how the Morphologi G3-ID can aid the development and manufacture of new, more efficient carbon-based battery electrodes.
