About Us

Paraclete means: “to come alongside”. We work alongside battery manufacturers, anode material suppliers, OEMs and researchers to enable them to produce the highest-energy, longest-lasting batteries.


Paraclete Energy was formed in 2007 as a Delaware “C” Corporation to produce low-cost nanoparticle silicon inks for the production of low-cost solar cells and panels. These silicon inks were made with functional groups covalently bonded to the silicon surface to allow a much wider optical spectrum band gap for higher photonic sensitivity.


This ability to produce low-cost silicon nanoparticles at room temperature with nearly any organic or inorganic material covalently bonded to the surface of the silicon has been found to be very beneficial in overcoming the typical problems of working with nanoparticle silicon with Li-ion batteries. In 2012, given the value that Paraclete’s low-cost, high capacity silicon nanoparticles could provide the emerging Li-ion market, Paraclete Energy turned its full attention to the storage market.


Paraclete Energy and its talented team of engineers and scientists working out of its laboratory and manufacturing facility in Chelsea, Michigan, have been developing, improving and selling tons of its SM-Silicon™ and other nanoparticle silicon products around the world.


Paraclete’s customers range from Tier 1 battery companies and anode suppliers to OEMs from nearly every industry using rechargeable Li-ion batteries to national laboratories and universities around the world. Paraclete’s silicon is also the standard silicon for the US Department of Energy’s National Laboratories Next Generation Anodes.


Paraclete can manufacture tons of many types of nanoparticle silicon metal, our premier silicon product is SM-Silicon™. The SM stands for Surface Modified. This surface modifier functions as an artificial SEI that negates the negative effects of electrolyte interaction and thereby enables very high loadings of silicon well beyond the ≈8% limit of silicon oxide. The SM also acts to create a covalently bonded network between the binder and carbon and other systems within the anode, and thereby the electrode is more capable enduring the stress associated with 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. SM-Silicon™ can be less expensive than graphite from a $/kWh. SM-Silicon™ can also be manufactured at the anode/graphite supplier or at the battery manufacturer’s facility.


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.


SM-Silicon™ is not just the same silicon metal or low capacity SiOx available from a supplier that sells the same silicon to any anode or battery company – it’s the customer’s specific and proprietary SM-Silicon™ high-capacity, cycle-stable solution!


Paraclete’s SM-Architecture™ enables its customers to develop a high capacity anode platform for immediate and long-term continuous improvement. SM-Architecture™ includes the ability to covalently bond nearly any organic or inorganic chemistry to the silicon’s surface with reactive functional groups on the opposite end ready to covalently crosslink with the binder and carbon systems. This creates a covalently bonded network between the systems within the anode and thereby the electrode is more capable of enduring the stress typically associated with silicon.


This multifunctional surface modifier creates a stable, covalently bonded, artificial SEI layer that is ionically conductive but electrically insulating. This artificial SEI and the covalent bond between the silicon and the binder and carbon systems create a stable network for the commercial viability of high capacity SM-Silicon™.


Paraclete’s SM-Silicon™ is based on high capacity 3,590 mAh/g, 99.5% silicon metal and NOT 1,550 mAh/g SiOx. Like graphite, Paraclete’s SM-Silicon™ has a tap density of 0.8g/cm3 and an ICL of only 8% while being priced less than graphite from a $/kWh.


Paraclete Energy has assembled a uniquely qualified team with remarkable records of achievement both academically and within the industry. The Paraclete Energy team are experts at making silicon work for our customers—today! We do not make silicon batteries, we enable our customers’ existing and next-generation batteries to be better with our silicon. Paraclete Energy’s success is measured by our customer’s success—specifically, by how our silicon nanoparticle materials enable our customers’ batteries to be the best they can be and to be clearly better than their batteries were without Paraclete’s silicon nanoparticles. This is the objective of all of Paraclete Energy’s research and development.


Paraclete Energy’s SM-Silicon™ is engineered to be added seamlessly to anode slurries used in current industry processes. SM-Silicon™, manufactured with both process and composite patent protection, is compatible in either aqueous or non-aqueous slurry systems. Paraclete offers SM-Silicon™ in 100 g bottles to 5-gallon buckets containing 10 kg and 55-gallon drums containing 100 kg, and other packaging as is appropriate for its customers. SM-Silicon™ at production quantities can be less expensive than graphite from a $/kWh. Licensing is also available.
