Core-shell Nanoarchitectures for Lithium-Ion Energy Storage Applications

  • Tomas M. Clancy (a1) and James F. Rohan (a1)


Multiphysics simulations (COMSOL) of core-shell nanoarchitectures show that they can operate at 3 times the C-rate of micron scale thin film materials while still accessing 90% of an additive free cathode oxide material. A high performance Ge anode DC sputtered onto a Cu nanotube current collector is characterised. Volume expansion of Ge is alleviated and mechanical stability is enhanced due to the Cu nanotubes current collector.
