A Novel, High-Capacity, Three-Dimensional Silicon Nanowire (SiNW) Anode for Lithium-Ion Batteries

Technology
Development of the next generation silicon nanomaterials-based anodes for high-performance and low-cost Lithium Ion Batteries, providing ten-fold capacity density relative to standard graphite anodes, and providing superior support for electric vehicles, storage devices and portable applications

Market needs:
Lithiation of silicon has one major problem -It is accompanied by a 400% volume increase and anode degradation! Also, issues of conductivity and limited diffusion exist

Key advantages:

  • Potential X10 energy density compared with current graphite anodes
  • Structurally stable after many cycles due to reduced stress
  • Open 3D structure enhances diffusion
  • Higher loading per area/volume
