Graphite intercalation compounds may offer keys to prolonging battery life

The beginning of this project dates back to 2012-2013, when team leader Ayrat Dimiev was working at Rice University, Houston, TX, USA, with Professor James Tour.

Together with Natnael Behabtu, at that time a PhD student of Professor Matteo Pasquali, they discovered a phenomenon that could be observed in optical microscope during the stage transitions in graphite intercalation compounds.

It took Dr. Dimiev six years of further research, including additional experiments at Kazan Federal University, to fully comprehend the driving forces behind the observed phenomena.

The experiments were conducted with participation from PhD graduate Ksenia Shukhina.

An important breakthrough came from the use of a new unique equipment, manufactured by the Belarusian company SOL Instruments, that allowed ultrafast Raman mapping of the graphite surface during the stage transitions.

Graphite intercalation compounds (GICs) are formed by insertion of certain atomic and molecular species between the graphene layers of graphite.
