About Us

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


Paraclete Energy manufactures nanoparticle 3,590 mAh/g silicon metal for the graphite and Li-ion battery industry. 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 ≈5% limit of silicon oxide.


SM-Silicon™ acts to compound the benefits to customers given now they can replace many times as much graphite with a prelithiated silicon metal that has over double the capacity of silicon oxide. Paraclete’s SM-Silicon™ can be priced from a dollar per kilowatt-hour perspective at less than graphite. The surface modifier is also what makes Paraclete’s silicon safe to handle in a battery manufacturing facility.


Paraclete Energy’s air and water stable prelithiated SM-Silicon/PL™ can be seamlessly integrated into customer’s standard aqueous slurry techniques and thereby enable much higher first cycle efficiency and much lower cost and time for production. The surface modifier not only acts as an artificial SEI but, with SM-Silicon/PL™, also acts as a protective shell from air and moisture.


Paraclete Energy also offers Rapid Prototyping Services for custom designing and making high-capacity SM-Silicon™-based batteries so that customers can test and prototype their next generation products. Paraclete’s SM-Silicon™, when combined with these services, enables customers’ next generation products and batteries to be prototyped and brought to market sooner.


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. Licensing is also available.
