Summary of the technology
A Novel, High-Capacity, Three-Dimensional Silicon Nanowire (SiNW) Anode for Lithium-Ion Batteries
Project ID : 3-2014-842
Details of the Technology Offer
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
