SiNode technology was developed and patented by Dr. Harold H. Kung and his students at Northwestern University.  The technology utilizes a composite material of silicon nano-particles and graphene in a layered structure. In effect, the flexible graphene scaffolds of our composite materials eliminate the rapid degradation of performance associated with silicon-based anode materials. In addition, in-plane nano-engineered porosity is introduced to the graphene layers, allowing rapid ionic diffusion through the structure.

SiNode exhibits these unique attributes:

  • mechanically flexible
  • electronically conductive
  • abundant charge carrying capacity
  • excellent high-rate lithium-ion storage capabilities

Performance

Superior Energy Capacity

Capacity comparisonThe initial capacity of SiNode anodes is aproximately 3200 mAh/g almost 10x that of current graphite anodes (370 mAh/g).  High energy density SiNode anodes allow for both a smaller battery form factor and extended range of use.

Superior High Power Performance

From normal to extreme power needs, SiNode’s unique structure allows for safe and rapid charge movement.  This performance opens up the possibility of high efficiency EVs and smart phones that can charge in minutes. Considerable optimization remains and performance is expected to continue improving.

Scalability

In comparison to other competing anode technologies, SiNode has a unique advantage as a highly scalable and low cost solution for large-scale production. Much of the synthesis procedure for porous graphene scaffold and the resulting composite relies on solution-based chemistry (modified Hummers’ method). Readily available industrial equipment such as drying oven and centrifuges can be used to maximize efficiency during scaled production. No specialized or custom-made machinery is necessary for any step of the production process.

Furthermore, the unique characteristics of our anode provide a number of manufacturing advantages and could eliminate the need for certain components required by current Li-ion batteries.

  5. This is amazing, it seem your SiNode technology will fgive us battries with an energy density the same as gasoline!!
    Is it possible to use this in a Lithiun Air battery for even greater energy density?
    Please add regular reports to your web site that gives news of the commercialization of this technology.

  6. Awesome, excellent work! This together with more efficient el-motors will enable a lot of exciting applications.

    I 2nd Stephen W. Foyle’s question and thought about adding regular reports. :)
