Our PhD student, Rafael Tomey, presented his cutting-edge research at the EMRS 2024 Fall Meeting, held from September 16 to 19 at the University of Technology in Warsaw, Poland. The presented work is titled “On 100% Pure Silicon Nanowire (Si NW) Electrodes as High-Performance Anodes for Next-Generation Lithium-Ion Batteries.”

These Si NW electrodes, produced through a single-step gas-phase process, eliminate the need for traditional multi-step fabrication methods like slurry casting, leading to cost reductions and improved energy density (up to 420 Wh/kg). The pure Si NW anodes delivered near-theoretical capacities and demonstrated excellent rate performance and cycling stability, with 75% capacity retention after 200 cycles and 100% retention over 1800 cycles at lower lithiation capacity. This work highlights the potential of pure Si anodes to meet the demands of future energy-dense batteries, paving the way for Si-specific electrolytes to further enhance performance.
