Paraclete Energy Inc. manufactures and sells nanoparticle custom surface modified silicon—SM-Silicon™—as well as  silicon nanoparticle composites with graphene, carbon, and polymer on the surface.

 

Paraclete Energy’s SM-Silicon™ offers 10x the capacity of graphite and 2.3x the capacity of silicon oxide (SiOx) while offering best-in-class cycle stability and pricing that can be less than graphite.  SM-Silicon™ is engineered to be added seamlessly to anode slurries used in current industry processes.

Silicon metal and silicon composites available in grams, kilograms, and tons.

  • nSiO – Silicon metal with oxide on the surface.
  • nSiH – Silicon metal with hydrogen on the surface.
  • nSi Raw silicon metal with substantially <0.5% impurities metals basis. This product is highly reactive to air.
  • nSi/C – Nanoparticle silicon metal with carbon on the surface.
  • nSi/Cg – Nanoparticle silicon metal with graphene on the surface.
  • nSi/Cg/P – Nanoparticle silicon metal with graphene and polymer on the surface.
  • SM-Silicon™ – Nanoparticle silicon metal with a proprietary Surface Modifier that acts as artificial SEI for cycle stability.
  • SM-Silicon/C™ – Nanoparticle silicon metal with a custom Surface Modifier optimized to the customer’s application, binder, electrolyte, and cathode system.
  • SM-Silicon/PL™ – Prelithiated nanoparticle silicon metal with a proprietary surface modifier that acts as a protective shell from air and moisture and as an artificial SEI.

* The composition would change by the specific surface modifier so identified for each respective product, (SM-Silicon™, SM-Silicon/C™, SM-Silicon/PL™, nSi/C, nSi/Cg, nSi/Cg/P, nSiO, nSiH) be it custom SM for our SM-Silicon™ or C, graphene, polymer or oxygen for the other R&D products.

SM-Silicon™ drums

SM-Silicon™

SM-Silicon™ is sold in 100g bottles, 10kg buckets or 100kg drums to companies in and suppliers to the battery industry for producing a premium product.

 

SM-Silicon/PL™

Pre-lithiated nanoparticle SM-Silicon/PL™ has a proprietary surface modifier that acts as a protective shell from air and moisture and has an artificial SEI. SM-Silicon/PL™ is scalable and commercially viable given it is stable and will thereby be safe to use in standard industry aqueous based processes used for making anode slurries.

nSi

Silicon Metal & Silicon Composites

Paraclete Energy sells silicon-based products and other composites typically sold in 100g R&D quantities but also available in 10kg buckets and 100kg drums, based on composites with carbon, graphene, and/or polymer.

Electric Vehicle charging

Professional Design, Optimization and Rapid Prototyping Services

Paraclete Energy will work with prospects and customers to design and then produce for their own testing proof-of-concept SM-Silicon™ based cells. This will include designing and optimizing the surface modification and the cell architecture that will be required to meet the specific high energy and/or high power or a combination of both objectives for a specific application, to include but not limited to $/kWh, Wh/kg, Wh/L, Ah and time/distance between recharge.
