Who Is Paraclete Energy?

See the SM-Silicon/3590™ Video


Paraclete Energy, Inc. manufactures high-capacity, nanoparticle Surface-Modified SM-Silicon™. This Surface Modifier acts as an artificial SEI for cycle stability. SM-Silicon™ is priced like graphite in production quantities. Paraclete has sold tons of its SM-Silicon™.

Paraclete Energy Is the Answer to the Commercially Viable Silicon Supply Chain and Performance Issues of the Li-Ion Battery Industry

Paraclete has already sold tons of its SM-Silicon™ to the Li-ion battery industry. Paraclete Energy’s SM-Architecture™ enables its customers to optimize the characteristics and properties of high-capacity silicon metal that makes SM-Silicon™ both commercially viable and unique and therefore proprietary just to them. This capability creates a platform for continuous improvement of the negative electrode. Paraclete Energy’s high-capacity silicon-metal-based SM-Silicon™ thereby becomes the customer’s optimized product for their specific batteries’ proprietary formulation.

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

  • nSiO – Nanoparticle silicon metal with oxide on the surface.
  • nSiH – Nanoparticle 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 – A composite of nanoparticle silicon metal with graphene on the surface.
  • nSi/Cg/P – A composite of 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™ is sold in 100g bottles, 10kg buckets or 100kg drums to companies in and suppliers to the battery industry for producing a premium product.



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.


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.
