Influence of carbonate-based additives on the electrochemical performance of Si NW anodes cycled in an ionic liquid electrolyte.

Stokes, Killian; Kennedy, Tadhg; Kim, Guk-Tae; Geaney, Hugh; Storan, Dylan; Laffir, Fathima R.; Appetecchi, Giovanni Battista; Passerini, Stefano; Ryan, Kevin M. (2020)

Addition of electrolyte additives (ethylene or vinylene carbonate) is shown to dramatically improve the cycling stability and capacity retention (1600 mAh g-1) of Si nanowires (NWs) in a safe ionic liquid (IL) electrolyte ...
Copper silicide nanowires as hosts for amorphous Si deposition as a route to produce high capacity lithium-ion battery anodes

Stokes, Killian; Geaney, Hugh; Sheehan, Martin; Borsa, Dana; Ryan, Kevin M. (American Chemical Society, 2019)

Herein, copper silicide (Cu15Si4) nanowires (NWs) grown in high densities from a metallic Cu substrate are utilized as nanostructured hosts for amorphous silicon (aSi) deposition. The conductive Cu15Si4 NW scaffolds ...
A copper silicide nanofoam current collector for directly grown Si nanowire network and their application as lithium-ion anodes

Aminu, Ibrahim Saana; Geaney, Hugh; Imtiaz, Sumair; Adegoke, Temilade E.; Kapuria, Nilotpal; Collins, Gearoid A.; Ryan, Kevin M. (Wiley and Sons Ltd, 2020)

Silicon nanowires (Si NWs) have been identified as an excellent candidate material for the replacement of graphite in anodes, allowing for a significant boost in the capacity of lithium‐ion batteries (LIBs). Herein, ...
