Structurally Defined Nanographenes for Efficient Energy Storage Devices | Hung-Ju Yen

Summary :
⁣This talk covers my recent work in the synthesis and structural design of functional nanographenes lithium ion batteries. We attempted a multi-step bottom-up organic synthesis of a series of 2D and 3D nanographenes with various functional groups attached to the edge of the graphene basil planes. The optimized electronic structure and facilitated electron transfer have led to energy storage ten times the capacity of graphite, especially at extremely high current density, suggesting that the optimal design of conjugated nanographenes is promising for next generation lithium ion batteries with superior energy storage efficiency and rate capability.
