Examination of the impact of electrolyte composition on high and low temperature performance of Ge/LCO full cells. Benchmarking vs graphite containing full-cells shows significant performance enhancement. Mechanistic insight into low temperature evolution of the Ge anodes was also provided.
Examination of the performance of colloidal WSe2 nanocrystals as anodes for lithium-ion batteries. Demonstrating the role of crystal phase and morphology in determining performance. Collaboration with UGhent
The study examines Cu15Si4 nanowires as a conductive scaffold/host for amorphous Si active material. The anode architecture allows for long term cycling stability by accommodating structural changes in the active Si.
Report examining the use of lignin derived carbon nanofibers as Li-ion battery anodes. The role of the biopolymer used in determining porosity and Li-ion storage capacity was details. Collaboration with Dr Maurice Collins.
Using a textured Cu foil for direct growth of Ge nanowires leads to significant performance enhancement compared to planar stainless steel current collectors. The areal capacity and cycling stability are dramatically enhanced and linked to increased stability of the active material during cycling.
Full cell testing of Ge nanowire anodes shows the impact of cell preconditioning, voltage windows and cathode capacity excess. The findings also demonstrate that half-cells may underestimate the rate performance of promising anode materials.
In her recent J. Phys. Chem. C paper @SarahfoleyJ showed that three different anode materials can be formed from the same starting material, sql-1-Cu-SNIFSIX. #battchat #batterytwitter
