High Efficiency Flexible Battery Based on Graphene-carbon Nanotube Hybrid Structure
Abstract
The following achievements have been make during tb.is project: ** A binder-free interface controlled CNTs based anode on Cu were synthesized-very high 1st cycle capacity(- 2500 mAh/g), at 1C (- 900 mAh/g) and at 3C rates (767 mAhlg), and high capacity retention at 1C rate for 50 cycles. ** Demonstrated a large scale flexible graphene electrode ** Fabricated an array structure of 30 CNTs-graphene on transparent and flexible polyethylene terephthalate (PET) film through a simple lamination process- structural integrity, low contact resistance, excellent C-rate capability and high Coulombic efficiency of over 99%. ** Multi-layered structure of Gr/Si-QDs anodes have been successfully fabricated - initial discharge capacity of2869 n1.Ah/g at 0.5 C and 895 mAh/g, 1 Cover 200 cycles. ** Graduated 2 Ph.D. students, 2 undergraduate students. Students received awards from intemational conferences: Awarded Graduate Excellence in Materials Science (GEMS) Award American Ceramic.
